6.4.7 Option -413 Calibration
If the IEC61000-4-13 auxiliary generator option is installed, the following calibration procedure
applies. Refer to for the locations of the adjustment pots on the Aux. Waveform Generator (CI
CAU tion when
P/N 7004-719-1).
TION: This will require the top cover to be removed. Always use cau
removing the top panel to not touch the LV supply. This procedure should
be performed by qualified personnel only
1. Select AC mode, 300V range, 0.0 Vac, 50 Hz. Do not apply a load. Close output relay.
2. Select
INTER HARMONICS the MENU 2 screen. The following values will be displayed:
