SIREC D Display Recorder 7ND4000

C. Point Tag - A Point Tag is a name used to
identify the point on the display or recorded file and
may be up to ten characters long. The point tag
appears on the bar graphs and Digital displays. To
program a point tag perform the following:
1. Use the UP (↑) or DOWN (↓) Arrow Keys to
highlight “Point tag" on the above menu and press
ENTER. The display will show the existing Point
Tag if any as "�POINT TAG�“.
2. Use the Alphanumeric keypad to enter up to ten
characters for desired Point Tag then press
ENTER to return to the Point Setup Menu.
D. Input Scale - Low and high input scale is
used for configuring the Recorder for the actual
input provided by the transducer. Input and Output
Scales control the conversion to Engineering Units.
Actual span of the input scale is set @ 180mV, 1V,
or 10V. Only voltage inputs require setting low and
high input range values. The following steps guide
you in programming Input Scale:
NOTE
During point programming, input range voltages
are programmed in the same engineering
units as the voltage range selected,
i.e. mV or Volts.
1. Use the UP (↑) or DOWN (↓) Arrow Keys to
highlight "Input scale". Press ENTER and the display
reads "lo�XXXXXXXXXXXXX�” (13 places
possible).
2. Use the numeric keypad to enter the Low End
Scale Value, the default is zero. Press ENTER
when the desired Lo Scale value is displayed and
the display reads "hi�XXXXXXXXXXXXX�".
3. Use the numeric keypad to enter the High End
Scale value, the default is the full scale value of
the range selected. Press ENTER when the desired
Hi Scale value is displayed and the display
will return to the "Input scale" Menu item.

E. Programming Output Scale - All linear
current and voltage inputs must be assigned low
and high output scale endpoints. The output scale is
used to linearly map the input range (set with the
Input scale option) to an Output range set with the
Output Scale option.
For example, if a transducer has a 1 volt output
equivalent to 5000 PSI, use the 1V input range with
an Input Range setting of 0 to 1.00 V and program
the Output Range to be 0 to 5000. The actual
readings on the display will now be in PSI.
Programming steps for Output Scale follow:
1. Use the UP (↑) or DOWN (↓) Arrow Keys to
scroll through the menu items in the Point Setup
Menu and highlight "Output scale". Press ENTER
and the display reads "places? X".
2. Use the UP (↑) or DOWN (↓) Arrow Keys to
scroll through the menu items to set the number of
decimal places (up to a maximum of 4 - NOTE 5 =
E notation) and press ENTER. The display will
read "lo�XXXXXXXXXXXXX�” (13 places possible).
3. Use the numeric keypad to enter the low end
scale value, the default is zero. Press ENTER
when the desired Lo Scale value is displayed and
the display reads "hi�XXXXXXXXXXXXX�".
4. Use the numeric keypad to enter the high end
scale value, the default is the full scale value of
the range selected, which is a direct linear mapping
or a scaling of 1. Press ENTER when the desired
Hi Scale value is displayed and the display
will return to the "Output scale" Menu item.
F. Programming Currents - This requires the
RTD option. Currents are used to measure a
resistance input on the back of the Recorder. If a
resistance other than an RTD is plugged into an
input, Currents must be enabled. The current on the
RTD option is typically 2.00mA. The procedure to
enable or disable currents follows.
1. Enabling or Disabling Currents - Use the UP
(↑) or DOWN (↓) Arrow Keys to scroll through the
menu items in the Point Setup Menu and highlight
"Currents". Press ENTER and the display reads
either "currents=NO" or "currents=YES".
2. Use the YES or NO Key to change the display
to the desired state of Currents. When the desired
Currents state is displayed, press ENTER to invoke
and the display returns to "Currents" in the
Point Setup Menu.
