The voltage applied to the item to be tested is measured in peak units independent of the position selected at the selector switch. In order to avoid damage to the capacitors to be tested, the DC output voltage is limited to 50kV.
The current ranges show a RMS value in the range of 30 and 1mA for the current flowing through the device being tested. In the AC mode this is true RMS value. In the case of DC this is a pulsating direct current if a resistor is being tested and a periodic charge current if a capacitor is in the test position.
In the 100µA range the leakage current of a capacitor can be measured. It must be noted that the DC voltage applied is pulsed (half wave rectification). Therefore the indicated current is a result of two currents, the leakage current and the charge current. Depending on the capacitance value and the level of the leakage current, the effect of the latter can be ignored.
Depending on the charge current and the leakage current present, the voltage on the capacitor is more or less affected by a ripple. The current shown is the average leakage current, depending on the ripple experienced.
