To measure current (set up the Meter as shown in
Figure 7):
1. Turn off power to the circuit. Discharge all high voltage
capacitors.
2. Set the rotary switch to the µA, mA or A range.
3. Press the yellow key to select DCA or ACA measuring
mode.
4. Connect the black test lead to the COM terminal and
the red test leads to the mA terminal for a maximum of
400mA. For a maximum of 10A, move the red test lead
to the A terminal.
5. Break the circuit path to be tested.Touch the black
probe to the more negative side of the break; touch the
red probe to the more positive side of the break.
(Reversing the leads will give a negative reading, but
will not damage the Meter.)
6. Turn on power to the circuit; then read the display. Be
sure to note the measurement units at the right side of
the display (µA, mA or A). When only the figure "OL"
displayed, it indicates overrange situation and the
higher range has to be selected.
7. Turn off power to the circuit and discharge all high
voltage capacitors. Remove the Meter and restore the
circuit to normal operation.
