8-2 Calibrating Analog Outputs and Inputs
Analog Outputs
To calibrate the TransPort 4-20 or 0-20 mA output, you need to
connect a multimeter or ammeter to the analog output connector
shown in Figure 8-2 below (refer to page 2-3 for more
information for connecting the analog output).
Figure 8-2: Analog Output Connections
The calibration procedure consists of calibrating the analog
output zero and then calibrating the full scale as described in the
following steps. The resolution of the analog outputs is 5.0 µA
(.03% full scale).
1. Press the [CAL] key to access the Calibration Menu.
2. Press [F1] to select “A/OUT”.
3. Select Output 1 or Output 2.
Press [F1] for Output 1 or
Press [F2] for Output 2.
