The test will last for 30minutes. The test will be repeated for the Group 2 and 3 using the Voltage setting from Table 9-2and the frequency from Table 9-1. The ← key (backspace) will terminate the test at any time.VOLT FREQ MAXThis test will set the voltage and frequency to levels defined by Table 9-2. The test will last for 30minutes. The test will be repeated for the EURO standard using the Voltage setting fromTable 9-1 and the frequency from Table 9-2. The CLR Key in local operation will terminate the testat any time. Group execute trigger will terminate the test remotely. The unselected phases willremain at 115 volts. The ← key (backspace) will terminate the test at any time.VOLT UNBALANCEStandard/Group RTCA Group1 Group2 Group3Voltage offset 6 6 6 9Frequency 400 400 360/650 360/800Table 9-3: Normal Voltage UnbalanceThis test will change the output voltage for each phase from 115 volts to 115V + offset. Refer toTable 9-3 for the offset value and the Frequency. The test will last 30 minutes. The test will berepeated for a second Frequency if applicable. The test can be terminated at any time.The ← key will terminate the test at any time.WAVEFORM DISTORTIONThis test will generate a 5% THD voltage distortion on the output voltage waveform. Thedistortion is generated by using a clipped sine wave. The test will last for 30 minutes. The ←key (backspace) will terminate the test at any time.VOLTAGE MODULATIONThis test requires a numeric value entry equal to the modulation rate in Hz. This entry valuemust be between 1 Hz and 200 Hz. The amplitude modulation is calculated based on themodulation rate as defined in Figure 9-4. This test will last for 2 minutes.
