7.8.5 Calibrate Analog Outputs

In this display, a quick test of the available analog outputs can be performed. In addition, an analog out-

put can be selected to enable the Live Zero feature.

7.8.5.1 Quick Test (Analog Outputs):

Carry out a Quick Test:

1. Open the rear housing part.

2. Set the current measurement for direct current (DC) on the multimeter.

3. Connect the multimeter to the analog output to be tested (Abb. 27, Seite 38).

4. Click Quick Test on the Analog Output to test.

5. Check on your multimeter whether the current changes every 3 seconds to the following values: 0,

Notice

After pressing the quick test button, the current signal is changed every 3 se-

conds, starting at 0 mA and ending at 20 mA.

Warning

Damage to the process control system

Incorrect currents at the analog outputs can damage the process control sy-

stem.

Disconnect all signal lines to the process control system before starting to test

the analog outputs (connections to the analog outputs / to terminal X101).
