Use the following procedure to calibrate the analog outputs if a meter
reading in the “
Analog Output Testing ” procedure differed by more than
one percent or after replacing the optional I/O expansion board.
Equipment Required:
Multimeter
1. Connect a meter to the channel to be adjusted and set to voltage or
current as appropriate.
Figure 7–11 shows the analog output pins and
Table 7–4 identifies the associated channels.
2. From the Main Menu, choose Service > Analog Out Cal .
The Analog Output Cal screen appears.
Note If Service Mode is not displayed, refer to “ Accessing the Service
Mode ” on page 7-4 , then return to the beginning of this step. ▲
3. At the Analog Output Cal menu, press to scroll to the desired
voltage channel or current channel corresponding to the rear panel
terminal pin where the meter is connected, then press
.
4. With the cursor at Calibrate Zero, press .
The Analog Output Cal line displays Zero.
Note When calibrating the analog output, always calibrate zero first and
then calibrate full-scale. ▲
5. Use until the meter reads the value shown in the Set
Output To line (0.0 V, or 0.0 or 4.0 mA), then press to save the
value.
