Figure 29: Measuring the output signal in VDC
1. Switch the measuring range of the multimeter to VDC.
2. Connect the multimeter to the signal lead and 0 V lead.
3. Connect the voltage supply (+12/24 V).
4. Connect 0 V (-0 V).

Figure 31: Measuring the output signal using a resistor
1. Connect the resistor to the signal lead and 0 V lead.
2. Switch the measuring range of the multimeter to VDC.
3. Connect the multimeter in parallel to the resistor.
When using a resistor of, for example, 100 W, the following values are displayed:
