I N T R O D U C T I O N
Thank you for purchasing the REI Advanced Spring Rater Program. This manual
explains the operation of the Advanced Spring 6 software package that is part of
your spring checker system.
The Advanced Spring 6 software runs under the Microsoft WINDOWS XP/Vista
operating systems. If you are new to these operating systems, refer to the
Microsoft manuals that were included with your computer. Go through the
tutorial and become familiar with window and mouse operations.
GETTING STARTED
This manual is written as a supplement to enhance your factory training, not
replace it. It is recommended that you read the entire manual before attempting
to operate the spring checker. Some things that may not be clear when first
encountered in the manual will be more fully explained later. As an aid, all
computer commands and options will appear as a different font: Computer
Command.
ICONS
Certain commands can be accomplished by clicking the icon on the tool bar below
the Menu Bar. Most commands can also be executed using hot key listed on the
hot key list or from the pull down menus
9

C R E A T I N G A T E S T
The create test wizard will walk you through creating a new test. Create test
can be launched through the TEST pull down menu, with the ctl + M hotkey
combination or the create test icon on the tool bar.
There are three areas that define a test. Pre stroke, test , and test points. Each area
can be edited after a test is created.
PRE STROKE
The pre stroke option will allow the operator to run the test specimen for a pre
selected number of cycles to a defined force.
The number entered in the RETURN POSITION box (Figure 1) will determine
where the ram will return to between each cycle.
10
Chapter
3
WARNING : the return position is a gap measurement, entering 0 would be
the platens touching.

Figure 1
TEST
The test window will set the test parameters. (Figure 2)
Figure 2
The following window (Figure 3) will set the force number used to calculate the
free length of the test piece. If zero is entered, the program will use the first non-
zero force measurement as a free height.
11

Figure 3
TEST POINTS
The test point window (Figure 4) sets the parameters that will determine the area
of the collection the program will use to calculate the spring rate. All data points
within the start and end points will be averaged to calculate rate.
Figure 4
12

If you select the point validation, (Figure 5) the program will report a pass/fail of
the returned data based on the validation points entered. You can select if the
validation should be applied to the compression, extension, average, or both
compression and extension.
Figure 5
The final window will prompt you to name the test. Each test must have a unique
name. You can create as many tests as you require.
13

Collecting data
To start a test click on the Test Icon in the toolbar, Test in the Hardware
menu, or the F11 hotkey.
The Spring Test window displays the test parameters for all created test. To create
a test, use the Create test wizard. A standard spring test will record data collected
dynamically at the interval selected for the complete test range. Click on the arrow
to the right of the select test window to view all created test.
The three areas of a test description can be edited from the tabs on this page. Pre-
stroke and test points can be enabled or disabled using the check boxes in the
window. (Figure 6)
Select Configuration – Defines the data card configuration that will be used for
this test. Unless you have created a new configuration this will always be Default.
Select the spring test to run – The pull down arrow to the right of this window
allows you to select a test from a list of test you have created. You can have as
many spring test created as you need. The parameters for the selected test are
displayed in the boxes below this window.
Peak force – the peak force at which the test will compress the spring, this is the
force where the machine will reverse from compression to extension.
15
Chapter
4

Test Speed – velocity in in/sec of the test.
Pause Time – dwell time at peak force.
Measurement Interval – displacement interval between data points.
Spring Height Force – The force the machine will use to define spring free height.
Start/End Point – These define the range the program will use to calculate spring
rate. These numbers may be changed after the test.
Figure 6
To continue the test, click the Start Test button.
From the spring test window (Figure 7) use the Measure Gap button when the
program does not have a gap measurement recorded (red light displayed). You will
need to measure the gap each time you start the program. You will be prompted
to enter a block height number if you are using a block between the platens when
measuring the stroke.
16

Insert a tool height number in the Tool Retainer Height box if you are testing the
spring with anything that adds to the free height of the spring. If a spring only is
being tested this will be set to zero.
Once the gap has been measured and your tool height entered set click Next.
Figure 7
1. The next window is a final warning that the test is about to start. The machine
will compress the spring to the peak force setting and return to home.
After the test is complete, the following window will give you a snapshot of the
collected data. (Figure 8) this window is saved and displayed under the Test report
tab. The force, displacement, and rate data at the bottom of the results page is
calculated based on the start and end points entered at the top of the page, this is
the test range. The point average rate number is an average of all rate data points
17

in the test range. The end point rate is an average of the rate at the start and end
point. Your start and end point numbers may be changed to view data from
different areas of the spring. This will not affect the saved data and this point data
may be viewed after the data is saved by using the point report. The start and end
points are the distances between the platforms unless you check Relative to Start
Point. If you enter a number not in the spring range (i.e. 3” displacement on a 2”
spring) the program will not complete the results section. From this window you
can click Finish to save the data file or save and repeat if you wish to run the same
test again or Batch test if this is the first of a batch of springs to be tested.
Batch Test
A batch test is designed to give users the ability to run a number of different
springs and save the data as one data file. After running the first spring replace the
spring in the machine and use the Batch Test Repeat button to re-run the same
test. After all the springs have been run, use the Finish button to save and name
the data file. The individual runs will be saved together in one data file and
identified by their respective run number in the batch.
18

Figure 8
Step Test
Unlike the standard dynamic collection test, the step test will collect data at user
defined displacement increments. The machine will stop and hold at each point
while the software makes the collection. This is a static collection unlike the
dynamic collect in other test types.
Point Test
Similar to the Step Test, the Point Test allows the user to define test points within
the range of the spring. This test is also a static collection where the sample settle
time can be entered.
Coil Bind can be evaluated during a Point Test when the option is selected. To
evaluate coil bind during a point test go to Hardware � Motor � Configure and
19

check the box under the Spring Test tab. When this is selected, the spring will be
compressed to the max force and coil bind will be determined. If the box is not
checked, the spring will not be tested to coil bind, the max force entered in the
test window will only be a maximum allowable force that the test is not to exceed.
Manual operation control
Clicking on the manual control icon will open the manual control panel. If
the gap has not been measured (red light on) you will need to measure the gap
before running any other test. From this window, the operator can manually
operate the rater to a displacement or force move. This window is useful to get a
force reading at a given displacement point. Gap Move will move the lower platen
to the desired gap spacing entered in the move target box. (Gap is the distance
between the spring platforms.) Absolute move will move the lower platen the
distance entered in the target box. Force move will compress the spring to the
force entered in the Force Target window. Relative move will move the lower
platform the distance entered in the Move Size window. You can click on the up
or down buttons to move the entered distance a number of times.

Analyzing your data
When the test is complete and you have named the file, the program will display
the trace of the last collected data file automatically. (Figure 10) File names are
displayed in the legend on the left side of the main screen. The program will
overlay all open data files. By checking or un-checking the boxes next to the file
name the operator is able to hide or show any open files. The compression,
extension, or average trace can also be displayed by checking the boxes in the
legend. The color of the file trace can be changed using the C hot key. Different
graph options are available in the Graph pull down menu or on the toolbar.
Graph properties can be modified in the Scale tab at the top of the graph, each
graph type is scaled independently. To close a displayed data file highlight the
data file and use the delete tool bar button or the delete button on your
keyboard, this only closes the file in the program, the file is still saved in the
original file location.
To aid the operator in analyzing the graph a movable curser and zoom window are
available. Click on the trace to place the curser and use the right and left arrow
keys to move the curser along the trace. The data from each data point will read
out on the status bar at the bottom of the screen. To zoom in on a section of the
graph place your curser at a point on the graph, hold down the left mouse button,
and drag a box around the area you wish to zoom, or use the zoom tool bar items
22
Chapter

Legend
To return to full view use the reset zoom button on the tool
bar. You can copy the graph to a document by clicking on the camera icon on the
toolbar, then click paste in a document.
Figure 10
By right clicking on the word Graph at the bottom of the legend, you can insert
more graphs. This allows another sheet to be opened with alternate data files.
Your data can also be viewed in numeric form by selecting the Report, Point
Report, and Statistical Report tab at the top of the graph. (Figure 11)
Data Report - The program will display the data for the file name that is
highlighted in the legend. The up and down arrows can be used to move between
files with the data window open. By using the Report box on the right of the
screen, you can define how the data is displayed. The numeric report can be
23

exported to a file or the clipboard in three different formats using the Export box
located under the Report box. Test report rates are an average of all data points in
the test range.
Point Report – The point repot can be used to find the force, displacement or rate
at any requested point or as a point referenced from the full length point of the
spring (if you enter 1” with the R box checked this point would be 1” from the
full length position). By default, the full-length point will automatically be the first
point in the report. If the R box is empty, that row will display data at that point in
force or displacement depending on the units you select.
Statistical Report – On this page you are able to compare all open data files. Use
the start and end point boxes to define the report area. Data for each spring will
be displayed as well as minimum, maximum, average, and standard deviation in
compression, extension, and average data. Like the data report page this page
displays a end point rate and a average rate.
24

Figure 11
The scaling tab can be used to define the scaling and orientation of the data on the
graph page. Auto scale will size the graph to fit the data trace. The span box will
define the minimum scaling of the graph when you are on auto scale. To use span
enter a scaling number in the span box (you must have auto scale checked) the
program will now keep your scaling at that span and place the trace on the middle
of the graph, if the trace is larger than the span the program will auto scale. Using
span on the rate axis will keep the trace in the middle of the graph no matter what
the rate. To set the scaling remove the check from auto scale and fill in your
scaling numbers. From this page, you can also define the number of lines per axis,
and invert the sign or axis for both the x and y.

MENUS
Each menu displays options and various tasks that can be completed within the
program. The following is a description of each menu, and what is found under
each menu heading. Please be aware that some sections are for advanced users
only and should not be used unless you are familiar with function of the option
and how it might affect the data.

New Template
Templates will save all open data files in one file. To make a new template, click
on New Template.
Open Template
This menu opens to the directory that stores all templates allowing the user to
select a preferred template.
Save Template
Allows the user to name the template when the save window appears. Templates
are saved to a separate directory and named by the user. This option can also be
used to save multiple traces on one graph.
Save Template As
Selecting this option will open the save template window. To save a new
template, give a name to your new template and click Save.
Open Spring Data
Use this selection to open and graph saved data files.
Print
All user defined print options are on this screen.
Graph Layout
The graph layout tab allows the user to size the graph, legend, and notes on the
paper to fit a custom format. (Figure 12) The numbers entered in the divider box
are the percentage of the page from top or left where each item will start. If the
notes were positioned at the bottom of the page and set on 90%, the note box
would start at 90% of the page as measured from the top of the page. The legend
and notes can be located on the left, right, top, and bottom of the page or hidden.
Moving an item will require a change in the page percent number to keep the
graph area the same. In most cases selecting the same print settings on different
28

machines will produce the same size graph on the paper, if you attempt to match
graph sizing on different printers it may be necessary to set the size number
different to create the same size graphs.
Show Logo- Check this box to include a logo on your printed graph. To select a
new logo click the button to the right of the status bar under the show logo box.
Select the bit map file you wish to use. The loaded logo file name will appear in
the status box. If you select stretch to fit, the program will fit the logo to the page
without changing the graph size. If this box is not checked, the program will
display the logo as the saved bitmap size.
Report Options
This page defines all parameters for the numeric reports that are printed. To print
only the graphs with no report remove all check marks on the Data Report section
of this page. To print only the reports without the graphs uncheck the print graph
box at the top of the page.
The graph and data can be printed on the same page by checking the Graph Size
box and adjusting the graph size to fit the data on the graph page. When printing
data and graph on the same page the lay out works best on portrait mode.
Report Fonts
This tab allows the user to change the font size, style, and color of different labels
and headings on the printed pages.

Grid, Cursor Styles, Fonts, and Trace Width can be modified from the graph page.
Trace Width will define the thickness of the data traces as shown on the monitor
and printed graph. (Figure 14)
Figure 14
Smoothing
Smoothing on this page only affects the look of the graph. This aids in comparing
different graphs, it does not affect the recorded spring rate number. REI
recommends a 25 smoothing on the rate channel. In most cases, all other channels
should have the smoothing set to zero.
33

Math Signals
Math signals are channels that are not collected but are created with a
mathematical operation using constants, math functions, and channels. Math
channels are treated the same as collected channels and may be graphed and used
in other math channels. The math syntax for creating math signals is listed at the
end of this manual in Chapter 7.
Field Defaults
Fields are the pages that have areas for the operator to fill in test and spring
information. The fields will be held with the test and displayed on the report tab.
The default page allows you to customize the fields to contain the information you
need.
Clicking on the edit test Defaults will open the window displayed below. (Figure
15) By clicking on a cell, you can change the name of a field or the number of
lines that will be reserved for that field. By using the INSERT key, new lines may
be added to expand the field page. To delete a line highlight the name by clicking
on it and use the DELETE key. The default boxes can be used for descriptions
that you want to appear with each saved data file as a default. Constants are
numbers that would be used with math channels. This window allows the user to
customize the data displayed on the report page.
34

Figure 15
Folders/Files
From this page, the user can define the default file name and default location of
the data files. By default the program will always return to the last used directory
when saving a data file. A user may select a new default location by clicking ‘Use a
predefined folder.’ The button to the right of the file name allows the operator to
select another file for the default directory. This page can also be used to define
the default file name (Spring Data by default) or have the program use the last
entered file name followed by a number that is automatically inserted as a default.
Snapshot
The graph snapshot option allows the user to customize the size of the captured
bitmap image when the snapshot function is used. The Snapshot Legend Width can
also be modified.

GRAPH
This menu allows you to select the graph format to display open data files. Select
the graph type you wish to use by clicking on the appropriate graph type or use
the hot keys. The following is a short description of each graph type. Options to
aid the user in viewing the data are explained in detail in the analyzing your data
section starting on page nine. Use the properties page in the Edit menu to find
options to change the layout of the graph.
Spring Rate vs Displacement
This graph depicts the spring rate by calculating the change in force divided by the
change in displacement between each recorded data point and plotting these
points against spring displacement. (Figure 16) The complete trace displays the
compression and extension data, the average is the average of the compression
and extension. Spring Rate vs Force is the same graph except the X-axis is
force.

37

Raw Force vs Raw Displacement
This graph shows the collected force values compared to displacement without
the internal filtering that is built into the program. (Figure 18) Other graphs are
filtered to eliminate electronic noise. Electronic noise may hurt the repeatability of
the data. You may view the raw numeric values by clicking the copy button in the
Edit pull down menu with this graph open, then open an MS Excel spreadsheet
and click on paste. No numeric data is available on the data page for raw data, the
raw numeric data must be viewed in Excel.

functions, unless specifically noted operate on all types of signals.
ABS ( expression )
Returns the absolute value of the ‘expression’.
SGN ( expression )
Returns the sign of the ‘expression’.
If expression is greater then 0, SGN returns 1.
If expression is equal then 0, SGN returns 0.
If expression is less then 0, SGN returns -1.
SIN ( expression )
SIN returns the sine value of ‘expression’. ‘expression’ is assumed to be in
radians.
COS ( expression )
COS return the cosine value of ‘expression’. ‘expression’ is assumed to be in
radians.
TAN ( expression )
TAN returns the tangent of ‘expression’, ‘expression’ is assumed to be in radians.
ASIN ( expression )
ASIN returns the sin-1 of ‘expression’.
40
Chapter
7

ACOS ( expression )
ACOS returns the cos-1 of ‘expression’.
ATAN ( expression )
ATAN returns the tan-1 of ‘expression’.
EXP ( expression )
EXP returns the values of ‘e’ to the ‘expression’ power, or e‘expression’.
LOG ( expression )
LOG returns the natural log of ‘expression’.
SQRT ( expression )
SQRT returns the square root of ‘expression’
DIFF ( expression )
DIFF differentiates ‘expression’ with respect to time. The sample rate of
expression is assumed to be that same of the data being used to evaluate
‘expression’.
INTG ( expression )
INTG integrates ‘expression’ with respect to time. The sample rate of expression
is assumed to be that same of the data being used to evaluate ‘expression’.
POSITIVE ( expression )
POSITIVE returns the value of ‘expression’ if it is greater then zero, otherwise
POSITIVE returns zero.
NEGATIVE ( expression )
NEGATIVE returns the value of ‘expression’ if it is less then zero, otherwise
NEGATIVE returns zero.
RAD ( expression )
RAD converts ‘expression’ from degrees into radians.
DEG ( expression )
DEG converts ‘expression’ from radians to degrees.
MIN ( expression1, expression2, expression3, … )
MIN evaluates each individual expression and then returns the minimum of all of
the expressions.
MAX (expression1, expression2, expression3, … )
MAX evaluates each individual expression and then returns the maximum of all of
the expressions.
41

AVE (expression1, expression2, expression3, … )
AVE evaluates each individual expression and then returns the average of all of
the expressions.
UNITS ( symbol , measurement )
UNITS ensures that ‘symbol’ is returned in ‘measurement’ units. For example, if
Displacement may be in inches or millimeters, UNITS(Displacement, {Mm})
would ensure the Displacement is in millimeters.
TOUNITS ( expression , measurement , targetmeasurement )
TOUNITS assumes ‘expression’ is in ‘measurement’ units and forces it to convert
to ‘targetmeasurement’ units.
SMOOTH ( expression , NUMBER )
SMOOTH evaluates expression and averages the values of ‘expression’ for each
of the ‘NUMBER’ data points before and after the each data point. For example
“SMOOTH(Displacement, 5)” would for each point of displacement it would
average the eleven data points to generate the value at that data point. (It uses
eleven because it takes 5 points from left, 5 points from the right and the data
point itself.)

Safety Considerations for
Maintenance Procedures
Disclaimer of Responsibility:
It is the responsibility of the personnel carrying out the maintenance procedures to ensure that sufficient
measures are taken to ensure that UNDER NO CIRCUMSTANCES can the test system move if any
maintenance work is being carried out.
Any site safety officers should also be on hand to check that measures are taken to prevent the movement
of the test system while maintenance is being carried out.
Roehrig Engineering, Inc. cannot be held responsible for any injury or death to personnel or for any
damage to equipment or to the building structure cause by the actuator falling while being removed from
the test system.
48

Machine Frame Components.
Refer to Parts List and Drawings for Machine Frame. Little or no maintenance is required for the
machine frame components. Most of these components, including the base frame, the bedplate, and the
columns are either fabrications or are machined and thus have no moving parts.
Cro shead
On some models the crosshead itself has clamp/unclamp bolts built into it as well as a clamp/unclamp
actuator. The crosshead also has an acme motor screw drive assembly, which may require periodic
maintenance.
Lock/Unlock – The crosshead is locked (clamped) in place through the use of two threaded bolts on
lever arms, which are attached to the electric actuator, which is free to move. As one bolt has right-hand
threads, and the other has left-hand threads, the actuator clamps the crosshead into position when the
electric actuator is fully RETRACTED. The crosshead is in the UNCLAMP position when the electric
actuator is in the fully EXTENDED position. NOTE that all motion of the Lock Unlock is
accomplished through the PLC Manual Screen, under Crosshead Control.
Crosshead-Raise/Lower
The Crosshead Raise/Lower motion is accomplished through the use of an acme screw assembly driven
by a reversing electric motor. The motor drives both acme screws synchronously through the use of a
timing belt, which will eventually require replacement if worn or aged. Please note that all motion control
for the Crosshead Raise/Lower is also accomplished through the PLC Manual Screen, under Crosshead
Control.
Recommended Spare Parts
Recommended spares have been broken down in distinct categories: Transducers, REI Custom
Parts/Assemblies, Fuse Chart, and Purchased Parts. Roehrig Engineering adheres to the policy that it is
not our intention to profit from spare parts, and provides this service to support previous sales. Items
such as Transducers, Fuses, and Purchased Parts can be obtained either through REI, with cost markups
to cover order processing charges, or can be obtained directly from the appropriate manufacturer. In the
event purchased items are obtained from REI, REI standard warranties apply. If spare parts are
49

purchased directly from manufacturers, warranty claims must be coordinated directly with the component
manufacturer.
Recommended Spare Parts is not intended to be an entire list of all potentially replaceable items, but
rather includes items that REI has identified as a component required for routine maintenance, a critical
component that deems the machine inoperable, or items that may have unusually long lead items.
