Voltage Measurement Definitions

Emonitor and the Enpac Ex support measurement definitions with units of
volts (AC or DC). You can collect several different types of voltage
measurements. This topic shows the typical measurement definition setup for
three voltage measurements.

Voltage is similar to other units in that you can collect magnitude, numeric,
spectrum, and time waveform voltage measurements.
