RESISTANCE MEASUREMENTS
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 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.
CONTINUITY CHECK
WARNING: To avoid electric shock, never measure continuity on circuits or wires that have
voltage on them.

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
position.
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.
Touch the test probe tips to the circuit or wire you wish to check.
4.
If the resistance is less than approximately 50
Ω
, 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
position.
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 “1”,
the diode is good.
B. If both readings show “1”, 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.
FREQUENCY MEASUREMENT
1. Set the function switch to the 20KHz position.
2. Insert the black test lead banana plug into the negative (-) jack
(COM) and the red test lead banana plug into the positive (+)
jack (F).
3. Touch the test probe tips to the circuit under test.
4. Read the frequency in the display. The digital reading will
indicate the proper decimal point, value.
CAPACITANCE MEASUREMENTS
WARNING:
To avoid electric shock, disconnect power to the unit
under test and discharge all capacitors before taking any
capacitance measurements. Remove the batteries and unplug
the line cords.
1. Set the function switch to the CAP position.
2. Insert the black test lead banana plug into the negative (-) jack
(COM) and the red test lead banana plug into the positive (+) jack
(CAP).
3.
Touch the test leads to the capacitor to be tested. The
display will indicate the proper decimal point, value.
TEMPERATURE MEASUREMENTS
WARNING:
To avoid electric shock, disconnect both test probes
from any source of voltage before making a temperature
measurement.
1. If you wish to measure temperature in
o
F, set the function switch to
the
o
F range. If you wish to measure temperature in
o
C, set the
function switch to the
o
C range.
2. Insert the Temperature Probe into the negative (-) jack (COM) and
the positive (+) jack (Temperature), making sure to observe the
position.
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. Touch the test probe tips to the circuit or wire you wish to check.
4. If the resistance is less than approximately 50Ω, an audible signal will sound. The display will
also show the actual resistance.
