Operating Instructions
AC/DC Current Measurements
1. Set the rotary function switch to the
1000ADC, 600ADC, 1000AAC, or
600AAC range. If the range needed
is not known, select the higher range
rst then move to the lower range if
necessary.
2. Pressthetriggertotheopenjawand
fully enclose one conductor.
3. TheLCDwilldisplaythereading.
AC/DC Voltage Measurements
1. Insert the black test lead into the negative COM terminal and the red
testleadintothepositiveVterminal.
2. SettherotaryfunctionswitchtotheVposition,andselecteitherAC
or DC with the MODE button.
3. SelectHz%orACVwiththeHz% button.
4. Connect the test leads in parallel to the circuit under test.
5. TheLCDwilldisplaythereading.
Resistance Measurements
1. Insert the black test lead into the negative COM terminal and the red
testleadintothepositiveVterminal.
2. Set the rotary function switch to the Ω position.
3. Touch the test probe tips across the circuit or component under test.
It is best to disconnect one side of the device under test so the rest
of the circuit will not interfere with the reading.

Diode and Continuity Measurements
1. Insert the black test lead into the negative COM terminal and the red
testleadintothepositiveVdiodeterminal.
2. Turn the rotary function switch to the Ω position. Press the MODE
button until the Diode Test indicator appears on the display.
3. Touch the test probes to the diode under test. Forward voltage will
indicate0.4Vto0.7V.Reversevoltagewillbeindicatedby"OL".

indicatedby"OL"inbothpolarities.Forcontinuitytests,ifthe
resistance is <40Ω, a tone will sound.
Capacitance Measurements
1. 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.
2. Set the rotary function switch to the CAP position.
3. Insert the black test lead into the negative COM terminal and the red
testleadintothepositiveVterminal.
4. Touch the test leads to the capacitor under test.
5. TheLCDwilldisplaythereading.

2. SelectACVwiththeMODE button and press the Hz/% button to
indicate "Hz" in the display.
3. Insert the black test lead into the negative COM terminal and the red
testleadintothepositiveVterminal.

Temperature Measurements
1. To avoid electric shock, disconnect both test probes from any source
of voltage before making a temperature measurement.
2. Set the function switch to TEMP. Press the MODE button to change
between °C and °F.
3. Insert the Temperature Probe into the negative COM and the
positiveVterminals,makingsuretoobservethecorrectpolarity.
4. Touch the Temperature Probe head to the area to be measured. Keep
the probe touching the part under test until the reading stabilizes
(about 30 seconds).
5. TheLCDwilldisplaythereading.
Note: To avoid electric shock, be sure the thermocouple has been removed
before changing to another function.
Non-Contact AC Voltage Measurements
1. SettherotaryfunctionswitchtotheVposition.
2. Touch the probe tip to the hot conductor or insert into the hot side of
the electrical outlet. If AC voltage is present, the detector will light up.
3. The conductors in electrical cord sets are often twisted. For best
results, rub the probe tip along a length of the cord to assure placing
thetipincloseproximitytotheliveconductor.
4. The detector is designed with high sensitivity. Static electricity or
other sources of energy may randomly trip the sensor.
