7.5 Current Calibration
The virtual load must be connected between the high potential terminal
CAUTION
and the ammeter input terminal to prevent a safety hazard.
7.5.1 ACA Current Calibration
(30uA and 300uA are for 19021, 19021-4 only)
■
Connect a 4.42pF capacitance load (60Hz equivalent impedance is 600M ) with a
20k
shunt resistance between the HV OUTPUT and the low potential terminal
(RTN/LOW) of the channel to be calibrated. Connect the handheld meter to the
Shunt resistor to measure the AC voltage.
