6.4.4 AC Input Circuits
This test can be performed by applying known values of voltage and current to the AC input
circuits and verifying that the values applied coincide with the values displayed on the LCD
screen.
The testing circuit is shown in Figure 6.4.4.1. A three-phase voltage source and a single-phase
current source are required.

If the setting is Primary (Display value = 1), change the setting in the "Setting (change)"
sub-menu. Remember to reset it to the initial setting after the test is finished.
