1. Insert the black test lead banana plug into the negative (COM) jack.
2. For current measurements up to 2000µA AC, set the function switch
to the µA position and insert the red test lead banana plug into the
µA jack.
3. For current measurements up to 200mA AC, set the function switch
to the mA range and insert the red test lead banana plug into the
200mA jack.
4. For current measurements up to 10A AC, set the function switch to
the A position and insert the red test lead banana plug into the 10A
jack.
5. Press the "MODE" button until "AC" appears in the display.
6. Remove power from the circuit under test, then open up the circuit
at the point where you wish to measure current.
7. Touch the black test probe tip to the negative side of the circuit. And
touch the red test probe tip to the positive side of the circuit.
8. Apply power to the circuit.
9. Read the current in the display. The display will indicate the proper
decimal point, value and symbol.
Resistance Measurements
WARNING:
To avoid electric shock, disconnect power to the
unit under test and discharge all capacitors before taking any
resistance measurements.
1. Set the function switch to the Ω position.
2. Insert the black test lead banana plug into the negative (COM) jack
and the red test lead banana plug into the positive Ω jack.
3. 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.
4. 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 function switch to the
2. Insert the black lead banana plug into the negative (-) jack (COM) and
the red test lead banana plug into the positive (+) jack (Ω).
3. Press the "MODE" button until the
4. Touch the test probe tips to the circuit or wire you wish to check.
5. If the resistance is less than approximately 30Ω, the audible signal
will sound. The display will also show the actual resistance.
Diode Test
WARNING:
To avoid electric shock, do not test any diode that
has voltage on it.
1. Set the function switch to
2. Press the MODE button until the
3. Insert the black test lead banana plug into the negative (-) jack
(COM) and the red test lead banana plug into the positive (+) jack (Ω).
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.
6. The diode or junction can be evaluated as follows:
A. If one reading shows a value and the other reading shows OL, the
diode is good.
B. If both readings show OL, the device is open.
C. If both readings are very small or 0, the device is shorted.
NOTE: The value indicated in the display during the diode check is the
forward voltage.
