Figure 21: 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:
