8-6 Calibrating Analog Outputs and Inputs
Low and High Calibration
Use the following steps to calibrate the inputs:
Calibrating the Low Input
1. Connect the low temperature reference (or current source) to
the temperature input (see Figure 8-3 on the previous page).
2. If you have not already, enter the Calibration Menu by
pressing the [CAL] key.
3. Press [F2] to select “A/IN.”
4. The prompt will ask you to select Input 1 or Input 2. Press
[F1] to select Input 1 or [F2] to select Input 2.
5. Depending on your calibration reference, press [F1] to select
“LOW” or [F3] to select “4mA.”
6. If you selected “LOW,” enter the low temperature reference
value (in either °F or °C depending on the units selected), then
press [ENT].
7. Press [F1] to select STORE or [F2] to select ABORT. The
prompt returns you to the start of the A/IN menu.
Calibrating the High Input
1. Connect the high temperature reference (or current source) to
the temperature input for supply (see Figure 8-3).
2. Depending on your calibration reference, press [F2] to select
“HIGH” or [F4] to select “20mA.”
3. If you selected “HIGH,” enter the high temperature reference
value (in either °F or °C depending on the units selected), then
press [ENT].
4. Press [F1] to select STORE or [F2] to select ABORT. The
prompt returns you to the start of the A/IN menu.
Note: If you cannot adjust the low and high reading, repeat the
procedures. If you still cannot successfully calibrate,
contact the factory.
