5. Turn on the power of the measured circuit, and then read the display. Be sure to note the
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.
