Differential voltage measurement

All analog inputs AIN1 ... AIN8 can also be configured as differential voltage inputs. The wiring of a pyranometer with a 0…100 mV output is illustrated in Figure 12.

Figure 12 Wiring of differential voltage measurement (pyranometer)

In this example, the AIN 1 signal type in the Analog inputs menu has to be set to Diff volt. 0.311 V.

The pyranometer in this example is configured in Measurement table as follows:
