How to Measure Voltage

Voltage is measured in two ways—measuring the analog voltage output from a sensor and measuring the power voltage—each of which is explained in this section.

Measuring the analog voltage output from a sensor

Measuring the analog voltage output from a sensor

The output voltage device can be measured by inputting + and − from the target analog voltage output circuit directly into a voltage input measuring instrument.

Measuring the power voltage

Measuring the power voltage

The voltage can be measured by connecting probes to the + and − terminals of the target voltage.
