2.1 Current Reversal Screen

This screen is one of the Voltage / Current Parameter Screens and is useful to indicate if current in any phase

is reversed or not. If current in any phase gets reversed, then corresponding phase will be indicated on this

screen.

This screen shows that currents in

L1 and L3 are reversed.

This screen shows that currents

in all three phase are correct.

This screen shows that the meter

has no current input.

2.2 Phase Rotation Error Screen

This screen is one of the Voltage / Current Parameter Screens and shows phase rotation information for the

phase sequence R-Y-B (L1-L2-L3).

This screen indicates that

Phase Sequence is

incorrect.

This screen indicates that

Phase Sequence is correct.

This screen indicates that all

three phases (voltages) are

absent.

User must check this screen in order to get correct readings when meter is connected.

This screen indicates that

either one or two of the

three phases (voltages)

are absent.
