measurement units at the right side of the display
(mA or A). When only the figure "1" displayed, it
indicates overrange situation and the higher range
has to be selected.
6. Turn off the power of the measured circuit and
discharge all the high voltage capacitors. Remove
the test leads and recover the measured circuit.
