AC/DC VOLTAGE MEASUREMENTS
CAUTION: Do not measure AC/ DC voltages if a motor
on the circuit is being switched ON or OFF. Large voltage
surges may occur that can damage the meter.

Insert the black test lead into the negative COM terminal
and the red test lead into the positive V terminal.
Set the function switch to VAC or VDC position.
Connect the test leads in parallel to the circuit under
test.
Read the voltage measurement on the LCD display.
AC/DC CURRENT MEASUREMENTS

Insert the black test lead into the negative COM
terminal and the red test lead into the positive µA/mA
terminal.
For current measurements up to 2000µA DC/AC, set
the function switch to the mA position
Press the MODE button to indicate “DC” / “AC” on the
display.
Remove power from the circuit under test, then open
up the circuit at the point where you wish to measure
current.
Touch the black test probe tip to the negative side of
the circuit.
Touch the red test probe tip to the positive side of the
circuit.
Apply power to the circuit.
Read the current in the display
RESISTANCE 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 into the negative COM terminal
and the red test lead into the positive Ω terminal.
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
8
CONTINUITY CHECK
WARNING: To avoid electric shock, never measure
continuity on circuits or wires that have voltage on them.

position.
2. Insert the black test lead into the negative COM terminal
and the red test lead into the positive Ω terminal.
3.
on the display
4. Touch the test probe tips to the circuit or wire you wish to
check.
5. If the resistance is less than approximately 150Ω, the
audible signal will sound. If the circuit is open, the display
will indicate “OL”.
DIODE TEST
1. Set the function switch to the
position.
2. Press the MODE button to Touch the test probes to the
diode indicate
on the display. under test.
Forward voltage will typically indicate 0.400 to 0.700V.
Reverse voltage will indicate “OL”. Shorted devices will
indicate near 0V and an open device will indicate “OL” in
both polarities
MAX Hold button

not change as readings change
9
2.Press the MAX hold button again to return to normal
operation.
Hold Button
The Data Hold function allows the meter to “freeze” a
measurement for later reference
1. Press the “DATA HOLD” button to “freeze” the display, the
“HOLD” indicator will appear.
2. Press the “DATA HOLD” button to return to normal
operation.
AUTO POWER OFF
The auto off feature will turn the meter off after 15 minutes.
REPLACING THE BATTERY
1. Remove the bottom cover and secure the screw.
2. Replace old battery with fresh Two 1.5V AAA & 9V type
battery.
3. Replace the bottom cover and secure the screw.
REPLACING THE FUSES
WARNING: To avoid electric shock, disconnect the test
leads from any source of voltage before removing the fuse
cover.
1. Disconnect the test leads from the meter.
2. Remove the protective rubber holster.
3. Remove the battery cover (two “B” screws) and the

battery.
Remove the four “A” screws securing the rear cover.
Lift the center circuit board straight up from the
connectors to gain access to the fuse holders.
Gently remove the old fuse and install the new fuse into
the holder.
Always use a fuse of the proper size and value
(0.2A/250V fast blow for the 200mA range).
Align the center board with the connectors and gently
press into place.
Replace and secure the rear cover, battery and battery
cover.

generator and
Amplifier
Note: Make sure the battery power is sufficient. Insufficient
battery power will lead to dimmed LEDs and incorrect
results.
Cable/Wire tracing
1.
Connect the tone generator to the cable
a) For cables terminated at one end, connect the red
alligator clip to a wire and the black alligator clip to
equipment ground
b) For unterminated cables, connect the red alligator
clip to one wire and the black alligator clip to
another wire.
c) For cables with modular connectors, plug the
RJ11 connectors directly into the matching cable
connectors.
2. Set the Tone Switch on(the Tone switch on down
11
positon).
On the amplifier probe, press and hold the side on/off
button.
4. Hold the insulated probe tip against the wire in
question to pick up the signal generated by the tone
generator.
5. Rotate the volume/sensitivity control on the top of the
probe for the appropriate level and sensitivity to
identify and trace the wire.
6. The tone will be the loudest on the wires connected to
the tone generator.
Note: A headphone jack is located on the bottom of the
probe.
3.
Identifying telephone cable Tip and Ring – Using
Alligator Clips
1. Switch the tone generator to the OFF position(the
Tone,Sel,Cont switch on up position)
2. Connect the red test lead to one line and the black
lead to the other line.
3. The LED color indicates the connection to the RED
test lead as:
GREEN = Ring side, RED = Tip side.
Identifying telephone cable Tip and Ring – Using the
RJ-11 Connectors
1. Switch the tone generator to the OFF position(the
Tone,Sel,Cont switch on up position)
2. Connect the RJ-11 connector mating cable connector.
3. The LED color indicates the condition of the telephone
jack wiring.
GREEN = Jack wired properly, RED = Jack wired with
reversed polarity.
12
Identifying telephone cable Line Condition
1. Switch the tone generator to the OFF position(the
Tone,Sel,Cont switch on up position)
2. Connect the red test lead to the RING side and the
black test lead to the TIP side.
3. The LED will indicate line condition by:
GREEN = CLEAR , OFF = BUSY, Flickering YELLOW
= RINGING
4. Switch the tone generator’s Cont switch to down
position to terminate the call.
Continuity testing
NOTE: To avoid electric shock ,before testing for
continuity,check line polarity to ensure that the line
is not powered.
1. Connect the test leads to the wire pair .
2. Switch the Cont Switch to down position.
3. The LED will glow bright GREEN for a low resistance
or continuity. The LED will glow less brightly as the
resistance increases and will extinguish at
approximately 10,000ohms.
Tone selection
The output of the tone generator can be set to continuous
or wobble. Use the Sel Switch on the Tone-generator to
change the tone of output to “continuity”(down position)or
“wobble”(up position)
Low battery indicator
When a low battery condition is detected.Low battey LED
13
will light up.
Battery replacement
1. The tone generator and Amplifier Probe require
one standard/Alkaline 9 Volt battery for operation.
2. slide back the battery cover to replace new battery.
Caution:
1.When the test over, keep the all Switches to off
position(up position).
2. Leaving the battery in the tester for long periods of time
without use could drain power from the battery
