Applying clamp sensors to lines to be measured

Always clamp the instrument around only one conductor.
Clamping the instrument around two or more of conductors
in a bundle prevents the instrument from measuring any
current regardless of whether the measurement target is a
single-phase or three-phase circuit.

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, current 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.
