Table 9-2: Normal Voltage and Frequency Maximum
This test will set the voltage and frequency to levels defined by Table 9-1. The
test will last for 30 minutes. The test will be repeated for the Group 2 and 3
using the Voltage setting from Table 9-2 and the frequency from Table 9-1. The
← key (backspace) will terminate the test at any time.
VOLT FREQ MAX
This test will set the voltage and frequency to levels defined by Table 9-2. The
test will last for 30 minutes. The test will be repeated for the EURO standard
using the Voltage setting from Table 9-1 and the frequency from Table 9-2.
The CLR Key in local operation will terminate the test at any time. Group
execute trigger will terminate the test remotely. The unselected phases will
remain at 115 volts. The ← key (backspace) will terminate the test at any
time.
VOLT UNBALANCE

Frequency 400 400 360/ 650 360/800
Table 9-3: Normal Voltage Unbalance
This test will change the output voltage for each phase from 115 volts to 115V
+ offset. Refer to Table 9-3 for the offset value and the Frequency. The test will
last 30 minutes. The test will be repeated for a second Frequency if applicable.
The test can be terminated at any time.
The ← key will terminate the test at any time.
