5 Output control

Connecting pin #5 to GND (pin #3) forces the probe to analog output mode. If an analog output configuration has not been selected, default 0 ... 10 VDC and 4 ... 20 mA scalings are used.

If pin #5 is not connected, the analog or digital output selected when ordering or set later through configuration is used.

Gray
Note that the probe always remains in analog mode when pin #5 is connected to pin #3, and cannot be switched to digital output in this wiring option.
