value and symbol.
RESISTANCE [Ω] MEASUREMENT
WARNING: To avoid electric shock, disconnect power to the unit under test and
discharge all capacitors before taking any resistance measurements. Remove the
batteries and unplug the line cords.
1. Set the function switch to the Ω position.
2. Insert the black test lead plug into the negative (COM) socket and the red test lead
plug into the positive Ω jack.
3. Press the MODE button until "Ω" appears in the display.
4. Touch the test probe tips across the circuit or part under test. It is best to
disconnect one side of the part under test so the rest of the circuit will not interfere
with the resistance reading.
5. Read the resistance in the display. The display will indicate the proper decimal point,
value and symbol.

CONTINUITY CHECK

WARNING: To avoid electric shock, never measure continuity on circuits or wires
that have voltage on them.
1. Set the range switch to the x))) position.
2. Insert the black lead plug into the COM socket and the red test lead plug into the
positive x))) socket.
3. Press the MODE button until "x)))" appears in the display.
4. Touch the test probe tips to the circuit or wire you wish to check.
5. If the resistance is less than 35Ω, the audible signal will sound. The display will also
show the actual resistance in ohms.

DIODE TEST

WARNING: To avoid electric shock, do not test any diode that has voltage on it.
1. Set the function switch to the
2. Insert the black test lead plug into the COM socket and the red test lead plug into
the socket.
3. Press the MODE button until "
4. Touch the test probe tips to the diode or semiconductor junction you wish to test.
Note the meter reading.
5. Reverse the probe polarity by switching probe position. Note this reading.
