FREQUENCY
This test will change the output frequency in the following sequence:
• 393Hz for 1 minute.
• 407Hz for 1 minute.
• 400Hz for 1 minute.
The ← key (backspace) will terminate the test at any time.
VOLT UNBALANCE
This test will change the output voltage for the selected phase only in the following sequence:
• 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.
• 244° for 1 minute.
• 240° for 1 minute.
If phase C is selected:
• 116° for 1 minute.
• 124° for 1 minute.
• 120° for 1 minute
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 sine wave. The test will last for 1 minute. The ← key
(backspace) will terminate the test at any time.
