4. Press the MENU button to store your selection. The meter
momentarily shows "STRD", followed by "RD.S.O" (Reading
Scale and Offset).
USING READING SCALE AND OFFSET
("RD.S.O")
There are two methods to scale this meter to display readings in engineering
units. The first method is to scale with known loads. Do this by applying
known loads to a transducer connected to a meter, or by simulating the
output of the transducer with a voltage or current simulator. The second
method is to scale without known inputs. Do this by calculating input
values based on the transducer specifications and manually entering them
through the keyboard.
Scaling
with Known Loads (On-Line Calibration)
For maximum resolution, find the maximum signal that will be applied to
the meter input.
* For regular voltage input, refer to the main body of Table
4-1 on the following page.
* For millivolt or milliamp input, refer to the main body of
Table 4-2 on the following page.
Set the DIP switch positions as indicated at the top of either Table 4-1
or 4-2. The numbers 1 through 8 in the top row of either table represent
DIP switches 1 through 8 and the O, C or X directly below the number indicates
the correct position of each switch.
* "O" switch should be open or up.
* "C" switch should be closed or down.
* "X" switch is used to control excitation (refer to Table 2-3
to determine correct position of these switches)
Once DIP switches have been positioned correctly, apply power. Proceed
to the "RD.CF" (Reading Configuration) and set R2 equal to the
value in the right hand column of the card.

To scale with known inputs: apply known loads to a transducer connected
to a meter, or simulate the transducer output with a voltage or current
simulator. To scale with known inputs, follow these steps:
1. Apply a known load equal to approximately 0% of the transducer
range.
2. Press the MENU button until the meter shows "RD.S.O".
3. Press the /TARE
button. The meter shows "IN 1" (Input 1).
"IN 1"
(Input 1) is the unscaled display reading at minimum input.
4. Press the /TARE
button again. The meter shows the last stored value for Input 1.
5. Press the /TARE
button once more. The meter shows the actual signal being received.
6. Press the MENU button to store this value as "IN 1".
The meter shows "RD 1" (Read 1).
7. Press the /TARE
button. The meter shows the last stored value for Read 1.
8. Press the /NT/GRS
button to change the value of your digits.
9. Press the /TARE
button to scroll horizontally to the next digit.
10. Press the MENU button to store this value as "RD 1"
(Read 1). The meter shows "IN 2" (Input 2).
"IN 2"
(Input 2) is the unscaled display reading at maximum input.
11. Apply a known load equal to approximately 100% of the transducer
range.
12. Press the /TARE
button. The meter shows the last stored value for Input 2.
13. Press the /TARE
button once more. The meter shows the actual signal being received.
14. Press the MENU button to store Input 2 value. The meter
shows "RD 2" (Read 2).
"RD 2" (Read
2) is the desired display reading at Input 2.
15. Press the /TARE
button. The meter shows the last stored value for "RD 2" (Read
2).
16. Press the /NT/GRS
button to change the value of your digits.
17. Press the /TARE
button to scroll horizontally to the next digit.
18. Press the MENU button to store this value as "RD
2" (Read 2). The meter momentarily shows "STRD", followed by
"RD.CF". Meter scaling is now complete.
Scaling without Known Loads
To scale without known inputs, calculate input values based on transducer
specifications and manually enter them on the via the front-panel push-buttons.
The following example assumes load cells with these specifications:
Maximum Load: to 100.0 lbs
Output: 3.1 mV/V
Sensor Excitation: 10 V dc
Output: 31 mV (3.1 mV/V) x (10 V)
1. Determine the correct values for "IN 1" and "IN 2",
based on the load cell specifications. In most cases, "RD 1 & 2"
are equal to the minimum and maximum of the transducer output span. The
example assumes "RD 1 & 2" are equal to the range of the load ("RD
1" = 0 and "RD 2" = 100.0). Calculate "IN 1" and "IN
2" using the load cell output span and the following equation:
"IN" = (Sensor
Output) x (Natural Gain) x (Multiplier)

for most applications.

3. Determine

0 to 100 mV range and 10 uV resolution ("R.2=4").
| Example:
|
"IN

| |
"IN
2" = (31 mV) x (1000 cts/mV) x (1.000) = 3100 |
| |
"RD

| |
"RD
