Adjust output of the Sine Wave Generator to 19.00VRMS or to maximum that
generator provides. To meet required accuracy the Voltage should be bigger than
5.00VRMS. Control the output voltage with the standard Wideband Voltmeter. Write
down the RMS Leakage current that the 620L meter indicates.
Change the output frequency of the Sine Wave Generator to 100 Hz and adjust the
output voltage to the same value.
Adjust the VR1 on the 620L to have the Leakage current as close as possible to the
value recorded above.
