Meter Screen 

The 

Meter

 screen shows numeric

 

readings for all selected phases.

Phasor Screen 

The 

Phasor

 screen shows voltage (long arrows with solid arrowheads), current 

amplitudes, and phase angles. This screen is used to verify proper test lead and current 

probe connections. You can use the V and A arrows on the upper right of the screen to 

change the scaling of voltage and current on the PHASOR diagram. 
You can easily correct an erroneous Recorder connection by going directly to 

Menu\1750 Setup\Phase Swap

 (

) and using the Recorder to internally invert a CT, 

swap a voltage or CT phase, or modify a scaling parameter, then return to the screen to 

verify that the correction has been made. There is no need to touch the cables. See “Phase 

Swap” later in the manual for additional information.
