Connecting clamp sensors to lines to be measured

Be sure to attach each clamp around only one conductor.
Correct measurement cannot be obtained if a clamp is
attached around more than one conductor.

Settings such as the current range, nominal input voltage, measurement
frequency, and event thresholds will be automatically configured based
on the selected connection mode.
(You will need to set the measurement line type, clamp sensor type, and external VT/CT ratio.)
Select from the five available patterns according to your objective. To investigate the cause of a
power supply issue, select the abnormal voltage detection pattern. To investigate power supply qual-
ity (i.e., to monitor a power system), select the basic power supply quality measurement pattern.
