(16) Press [STOP][START] to read the ammeter value, ex. 4.85mA.
(17) Press [INC.] or [DEC.] until shows 4.85mA and then press [ENTER] for saving.
(18) Press [STOP] to stop DCA 5.0mA range full scale calibration.

ARC Calibration
4.4.1 Connection Diagram
1. ARC calibration is very special, the high voltage terminal are in
outside. Be careful with it as it may cause hazard.
2. Please contact your local agent for more detailed descriptions.
4.4.2 AC ARC Calibration (AC MODE)
■
Connect one terminal of dummy load resistor 250k
Ω
, 5 Watt or higher to high voltage
output terminal and get closer to low potential terminal of the HiPot tester gradually.
However, do not connect the HiPot tester to another terminal of resistor and generate
sparking between these two.
(1) Press [UP] or [DOWN] to select AC ARC calibration.
(2) Press [SETUP] [READING] to enter ARC reading setting.
(3) Press [INC.] or [DEC.] until shows the reading is (OUTPUT/READING)*1.414,
((1.25kV/250k
Ω
)*1.414)=7.7mA.
