Using Power Quality Measurements
Background
For typical power measurements, one channel is
used to measure voltage using a differential probe
and the other channel is used to measure current
using a current probe.
In the example below, the power quality of an AC
power source is tested.
WARNING
Ensure safe working practices are adhered to when
working with live voltages. Failure to do so could
lead to electric shock or loss of life.
Connection
Differential probe: Line and Neutral.
Current probe: Line.
Setup
1. Deskew the current and voltage
probes.

2. With the power disconnected from the AC
power source, connect the differential voltage
probe to the Line and Neutral wires and the
current probe to the Line wire.
3. Connect the differential probe and current
probe to an input channel.
4. Configure the channel with the differential
probe to the following settings:
