6.4.4 AC Input Circuits
This test can be performed by applying the checking voltages and currents to the AC input
circuits and verifying that the values applied coincide with the values displayed on the LCD
screen.
The testing circuit for Model 100 series is shown in Figure 6.4.2. A single-phase voltage source
and two single-phase current sources are required. (Test Model 200 series by same testing
method of Model 100 series.)

Check that the metering data is set to be expressed as secondary values (Display value = 2) on
the "Metering" screen.

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.
Open the "Metering" screen in the "Status" sub-menu.

Apply the rated AC voltages and currents and check that the displayed values are within
5%
of the input values.
