112V for 1 minute.

118V for 1 minute.

115V for 1 minute.

The test will be repeated on three phase systems to include all three phases if the coupling is set
to all.

The

key (backspace) will terminate the test at any time.

PHASE DIFFERENCE

This test applies to three phase systems only. The phase angle for the selected phase will
change relative to phase A in the following sequence:

If phase B is selected:

236

for 1 minute.

240

°

for 1 minute.

If phase C is selected:

VOLTAGE MODULATION

This test will vary the output voltage by

±

2.5V rms over a period of one second. The test will last

for 2 minutes. The

key (backspace) will terminate the test at any time.

FREQUENCY MODULATION

This test will vary the output frequency by

±

4Hz over a period of one minute. The test will last

for 4 minutes. The

key (backspace) will terminate the test at any time.

WAVEFORM DISTORTION

This test will generate a 5% THD voltage distortion on the output voltage waveform. The
distortion is caused by using a clipped sinewave. The test will last for 1 minute. The

key

(backspace) will terminate the test at any time.
