User Manual 



TRIGGER HYSTERESIS: select a value of 1%, 2%, 5% or 10% by pressing the ¤or the ˘ 

button, or by pressing ENTER. 

Hysteresis is the lagging, retardation or resistance that takes place when a force (e.g. inertia produced 

by velocity) acting upon a mass is changed. The trigger hysteresis setting is of particular value in 

dynamic vehicle testing (e.g., brake tests) due to this effect. 

For example, if a heavy vehicle with a low-powered engine is accelerated while traveling at a high 

velocity (e.g.100 km/h), acceleration tends to be relatively slow. As a result, the speed may fluctuate 

from 99 km/h, to 100 km/h, then back to 99 km/h, and so on. If the trigger is set to start the braking 

measurement at 100 km/h, the brake test would start while the vehicle is still accelerating, thus 

yielding an incorrect measurement. 

The Trigger hysteresis function provides a means of correcting for this effect by allowing an additive 

adjustment of the trigger value in the following selectable increments: 0%, 1%, 2%, 5% and 10%. In the 

above example, in which the Start trigger is set to 100 km/h, the following velocities would result: 100 

km/h (0%), 101 km/h (1%), 102km/h (2%), 105 km/h (5%) and 110 km/h (10%). The adjusted velocity 

value (the Trigger hysteresis value) must first be exceeded before the measurement can begin.

User Manual 




FIX: select ON to activate the FIX function. NOTE: For the FIX function to be operational, the LEAD 

function must be ON and a STEP value must be entered (see STEP, below) . 

As with the STEP function (described below), the FIX function is used to determine the interval at which 

each consecutive line of data is to be displayed. However, in addition to determining the interval 

between lines of data, FIX sets the first line of data to display as an actual acquired value, then rounds 

that value to the nearest whole number. This initial whole number is not displayed, but is used as the 

starting point at which the interval determined by the STEP value begins to generate each subsequent 

line of data. For example, if the STEP value for the distance channel is fixed at 10, a line of data will be 

displayed every 10 units (units correspond to prior channel settings), and each line will be a whole 

number. Therefore, if a brake test starts at 106 Km/h, the FIX function will set data lines at 100 km/h, 

then 90, 80, 70, and so on. 

DECIMAL: select the number of digits (from 0 to 3) to be printed to the right of the decimal point. 

DIGITS: use the pulldown menu to select the maximum whole number of characters (from 5 to 10) 

to be printed in one column. NOTE: the maximum number of characters per column is 40. Exceeding 

the maximum will cause the table to print incorrectly! 

STEP: enter a STEP value. The STEP value determines the interval at which each consecutive line 

of data is to be displayed. For example, if the STEP value for the distance channel is set to 10, a line 

of data will be displayed every 10 units (units correspond to prior channel settings). Therefore, if a 

brake test starts at 107.5 km/h, the next value will be 97.5, then 87.5 and so on. NOTE: the STEP 

function is applicable to lead channels ONLY; the LEAD setting must be set to ON in order to activate 

the STEP function.

DAS-2A Printer 

Replacing the printer paper roll 

A 

Quick and easy method: 

The appearance of red stripes on the printer paper indicates that 

approximately 50 cm remains on the installed roll. Replacing the 

paper at this time is a very simple process: 

1. Unscrew the two knurled screws at the lower face of the 

printer and pull the printer out from the DAS-2A housing. 

NOTE: It is normal to feel some resistance when doing this. 

2. Working from the inner side of the printer, cut the paper (the 

cut should be straight as shown in (Fig. A). DO NOT pull the 

paper through the printer face, and be sure to leave at least 

5 cm of paper behind the printer face. 

B 

3. Using adhesive tape, splice the end of a new paper roll to the 

5 cm section of paper that remains in the printer face (Fig. B). 

The end of the new paper roll should overlap the remainder of 

the old roll. Also, be certain that the ends of both paper rolls 

are straight and fully aligned when joining them together. 

4. Cut-off any excess adhesive tape that may jut out at the left 

and right of the paper (Fig. C). 

C 

5. Put the paper roll back into the printer (Fig. D) and slide the 

printer into the DAS-2A by applying light pressure. Then, 

re-tighten both of the knurled screws and supply power to the 

DAS-2A. 

6. Press the printer paper feed switch until the spliced section of 

paper feeds through the printer face. Remove and discard the 

spliced section. 

The DAS-2A printer is now ready for operation.

Versions 

Upon opening the Measurement settings tab, select DAS2 in the left column. 

This will provide access to the following: 

Firmware version - the version number of the firmware installed on the connected DAS-2A system. 

Add-in version - the version number of the CeCalWin-DAS Software presently in use. 

Compatibility to ver. - use the pulldown menu to match the CeCalWin-DAS Software version to the 

firmware version installed on the connected DAS-2A system. If the Software and Firmware share the same 

version number, or if the Firmware version is newer than the Software, select “Compatible with newest 

Firmware. If the CeCalWin-DAS Software is newer than the Firmware, select the compatibility option that 

corresponds to the older installed firmware version. 

NOTE: When the option is selected to make CeCalWin-DAS Software compatible with an earlier 

version of the firmware, any features or functions new to the latest version of the CeCalWin-DAS 

Software will become unavailable. Therefore, opting for compatibility with a previous firmware version 

makes the DAS-2 Add-in Software functionally equivalent to an older software version. For example, 

if the CeCalWin-DAS Software in use is version 1.20.00, but the Firmware version on the connected 

DAS-2A unit is 1.10.004 (as shown above), and the option is selected to make the CeCalWin-DAS 

Software compatible with the earlier version of the Firmware, the CeCalWin-DAS Software will 

provide only the features and functions available in the earlier version of the CeCalWin-DAS 

Software. The preferred option in this case is to update the firmware (see Appendix B: Updating 

the Firmware, p. 127, for complete details).

Common mask 

for job file names 

Features 

The Features section displays information about the hardware configuration of the connected DAS-2A. 

Common mask for Job file names 

The “Common mask for Job file names” function provides a way to automatically insert characters into 

individual job file names for the purpose of easy identification and organization. More specifically, job 

files that share common, or related characteristics, such as a date, a vehicle name, a test location 

and/or a numeric code, etc., can be assigned a common mask name that identifies each as being part 

of a related set of test files. 

Up to 6 identifying alphanumeric characters can be inserted into job file names by entering the desired 

characters into the “File name mask” field and clicking on the Set button. As described above, 2 numeric 

characters are automatically added to the end of the filename, in sequence, from 01 to 99. NOTE: 

It is best to limit common mask names to 2-3 characters. Using all 6 available characters will cause the 

original file name to be completely replaced by the common mask name. 

As an example, a File name for JOB1 (for more information about creating file names, see File name, 

page 114) could be configured as a brake test and labeled “brk”; a File name for JOB2 could be configured 

as a 0-60 test and labeled “060”, and so on. As jobs are run, CeCalWin-DAS automatically 

appends file names with a 2-digit numeric designator, which increases sequentially. For example, File 

names for the brake test configuration described above would appear as “brk01”, “brk02”, “brk03”, etc. 

ranging up to “brk99”. NOTE: Only the characters “A...Z”, “a...z”, “0...9” and the underscore “_” can be 

used to name files. 

Now, assume that "WIN" had been entered as the Common file mask to indicate a session of winter 

testing. This Common file mask can be added automatically to File names by adding one lower-case 

"x" (used as a placeholder character) for each character in the Common file mask, immediately before 

the File name. NOTE: the number of placeholder characters must be exactly equal to the number of 

characters in the Common file mask name. Therefore, by naming the file "xxxbrk", the File names will 

be designated automatically as "WINbrk01", "WINbrk02", etc., up to "WINbrk99". Common mask 

names can be repositioned within job file names by using the characters, "*" or "" as placeholders within 

the Common file mask name. For example, by entering "***WIN" or "WIN" as the common mask 

name, the file name will be formatted as "brkWIN01". Placeholder characters can be positioned anywhere 

within the job file name.

General settings 

Setting-up a job: General settings 

To view the General settings section, click on the "+" next to any JOB, then click on General to 

access and configure job parameters as desired. 

Available parameters include: 

• Rate (sampling rate) 

• Trigger hysteresis 

• Autosave 

• Start trigger 

• Stop trigger 


User Manual 


Rate - use the pulldown menu to select a sampling rate of either 100 ms or 50 ms. 

Trigger hysteresis* - use the pulldown menu to select a value of 1%, 2%, 5% or 10%. 

*Hysteresis is the lagging, retardation or resistance that takes place when a force (e.g. inertia produced 

by velocity) acting upon a mass is changed. The trigger hysteresis setting is of particular value in 

dynamic vehicle testing (e.g., brake tests) due to this effect. 

For example, if a heavy vehicle with a low-powered engine is accelerated while traveling at a high velocity 

(e.g.100 km/h), acceleration tends to be relatively slow. As a result, the speed may fluctuate from 99 

km/h, to 100 km/h, then back to 99 km/h, and so on. If the trigger is set to start the braking measurement 

at 100 km/h, the brake test would start while the vehicle is still accelerating, thus yielding an 

incorrect measurement. 

The Trigger hysteresis function provides a means of correcting for this effect by allowing an additive 

adjustment of the trigger value in the following selectable increments: 0%, 1%, 2%, 5% and 10%. In the 

above example, in which the Start trigger is set to 100 km/h, the following velocities would result: 100 

km/h (0%), 101 km/h (1%), 102km/h (2%), 105 km/h (5%) and 110 km/h (10%). The adjusted velocity 

value (the Trigger hysteresis value) must first be exceeded before the measurement can begin. 

Autosave - click the radio box to the left of the desired Autosave function. 


No - a dialog box appears at the conclusion of each test to ask if measurement data should be saved. 

Yes - measurement data is saved automatically at the conclusion of each test. 

Smart - this function makes it possible to automatically save only the data that you want to print 

at the conclusion of the test. See Setting-up a job: Print settings, page 110, for complete 

details about selecting data to be printed. 

No Save - measurement data is never saved. 


User Manual 


Start trigger and Stop trigger - Start and Stop Triggers are the conditions that can be specified 

to start and end measurements. All available channels of the DAS-2A can be used for triggering. This 

means that, in addition to standard pulse signals from sources such as a brake switch or light barrier, 

specific acquired values can be configured as trigger conditions as well. 

The Start and Stop triggers sections include identical parameter sets, which are described below. When 

creating a trigger equation, begin with the Function setting in the top row and work across the row from 

Signal, to Operation, to Value. More complex, multi-dimensional trigger conditions can be set-up by 

using the second and third lines to add additional AND/OR conditions to a trigger. 

Function - use the pulldown menus to select the desired function options. 

• Top row - selectable options in the top row are limited to ON or OFF.

Trigger settings: examples 

Example 1: basic start/stop configuration 

Example 1 is a simple start/stop configuration. The measurement will start automatically when the 

vehicle begins to move (i.e., when the velocity value is greater than zero) and will end automatically 

when the vehicle speed is greater than 100 km/h. 

Example 2: brake test configuration 

Example 2 is a simple 50-0 brake test. The measurement will start automatically when the vehicle 

speed is greater than or equal to 50 km/h AND the brake switch is activated. The measurement will 

end when speed value is less than or equal to 0 km/h.

User Manual 


Column - use the column settings to configure each of up to 5 columns to be printed. 

NOTE: When setting-up columns, be aware that both the DAS-2A integrated printer and the optional 

serial printer (Art. No. 11365) provide space for up to 40 characters per line. Spaces between columns 

and characters used to indicate line Status (see Status, p. 110) are included in the character count. 

Column - click on the name of column to be configured. 

Parameters for each column must be configured individually. 

Settings 

Channel - use the pulldown menu to select any one of the available channels. 

Visible - click the checkbox to include the selected channel on the printout. 

Lead - click the checkbox to mark the selected channel as a lead channel on the printout. Every column 

can be a leading channel. With several leading channels, you can handle v.s.t steps. 

Fix - click the checkbox to activate the FIX function. NOTE: For the FIX function to be operational, the 

LEAD function must be ON and a STEP value must be entered (see STEP, below). 

As with the STEP function (described below), the FIX function is used to determine the interval at which 

each consecutive line of data is to be displayed. However, in addition to determining the interval between 

lines of data, FIX sets the first line of data to display as an actual acquired value, then rounds that value 

to the nearest whole number. This initial whole number is not displayed, but is used as the starting point 

at which the interval determined by the STEP value begins to generate each subsequent line of data. For 

example, if the STEP value for the distance channel is fixed at 10, a line of data will be displayed every 10 

units (units correspond to prior channel settings), and each line will be a whole 

number. Therefore, if a brake test starts at 106 Km/h, the FIX function will set data lines at 100 km/h, then 

90, 80, 70, and so on. 

Reset - the reset function allows cumulative values to be re-set to zero as described below. 

Use the pulldown menu to select one of the following options: 

• OFF - the reset function is switched off. 

• By start - cumulative values (time, distance, etc.) are re-set to zero when a start 

trigger is activated. 

• By line - cumulative values are re-set to zero after each line is completed. 

Decimal - use the pulldown menu to select the number of digits (from 0 to 3) to be printed to the right of 

the decimal point. 

Digits - use the pulldown menu to select the maximum whole number of characters (from 5 to 10) to be 

printed in one column. NOTE: the maximum number of characters per column is 40. Exceeding the maximum 

will cause the table to print incorrectly! 

STEP: enter a STEP value. The STEP value determines the interval at which each consecutive line of 

data is to be displayed. For example, if the STEP value for the distance channel is set to 10, a line of data 

will be displayed every 10 units (units correspond to prior channel settings). Therefore, if a brake test starts 

at 107.5 km/h, the next value will be 97.5, then 87.5 and so on. NOTE: the STEP function is applicable 

to lead channels ONLY; the LEAD setting must be set to ON in order to activate the STEP function. 


User Manual 


Statistics 

Click the checkboxes to select the statistics to be included on the printout: 

Min - the minimum value acquired between the start and stop triggers. 

Max - the maximum value acquired between the start and stop triggers. 

Average - an average of all the values acquired between the start and stop triggers. 

Total min* - the minimum value acquired between system start and the stop trigger. 

Total max* -the maximum value acquired between system start and the stop trigger. 

Total average* - an average value acquired between system start and the stop trigger. 

*NOTE: Total statistics are based on raw data (*.d2f file). 

Extra value - this function provides for the display an extra step value, which can be defined freely. 

For example, if the Step value is set to print in steps, or increments, of 10 (10, 20, 30, ...) it is also 

possible to add a line to be printed at any desired value, such at 26. To enter an Extra value, simply 

click the “Extra value” checkbox and enter the desired numeric value in the field below it, which will

with a 2-digit file number, which increases sequentially. This process conforms to the DOS convention, 

which allows up to 8 characters in a name, plus an additional 3 characters that function as the file extension 

(*.TAB, .*.END, *.D2F.) 

The highest allowable file number is 99. If the maximum file number of 99 is reached, the message NO 

FREE JOB FILE Nr will be displayed and no additional files will be created. 

NOTE: Only the characters “A...Z”, “a...z”, “0...9” and the underscore “_” can be used to name files.
