Dc Current Calibration - QuadTech Guardian 5000 Instruction Manual

4.3.6 DC Current Calibration

Connect a load resistor (10 Mohms) between the Hipot H.V. OUTPUT of the Guardian 5000
and the High terminal of the DC ammeter. Connect the Low terminal of the DC ammeter to
the LOW DRIVER terminal (black) of the Guardian 5000.
