4 Using the Digital Multimeter
With no signal present, set the rotary switch to the desired
measurement function. Ensure proper insertion of the test leads so
they correspond with the type of measurement you wish to perform.
When connecting the test leads to the circuit or device, connect the
COM test lead (black) before connecting the live lead (red). When
removing the test leads, remove the live lead first.
WARNING
To avoid electric shock, injury, or damage to the meter, disconnect
circuit power and discharge all high-voltage capacitors before
testing resistance, continuity, diodes, or capacitance.
CAUTION:
Always connect the test leads to the meter’s inputs first before
connecting the DUT to avoid potential shock hazard.
1. DC and AC Voltage Measurements
The meter’s DC voltage ranges, , are 200 mV, 2 V, 20 V, 200 V,
and 1000 V. The AC voltages ranges, , are 2 V, 20 V, 200 V, and
750 V. Turn the rotary switch to the corresponding symbol for the
