Operation
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.
1. Insert the black test lead into the negative COM terminal
and the red test lead into the positive V terminal.
2. Set the function switch to VAC or VDC position.
3. Connect the test leads in parallel to the circuit under
test.
4. Read the voltage measurement on the LCD display.

8
AC/DC CURRENT MEASUREMENTS
1. Set the function switch to the µA/mA position.
2. Insert the black test lead into the negative COM
terminal and the red test lead into the positive µA/mA
terminal.
3. For current measurements up to 2000µA DC/AC, set
the function switch to the mA position
4. Press the MODE button to indicate “DC” / “AC” on the
display.
5. Remove power from the circuit under test, then open
up the circuit at the point where you wish to measure
current.
6. 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.
7. Apply power to the circuit.
8. 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 Ωposition.
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

9
test so the rest of the circuit will not interfere with the
resistance reading.
4. Read the resistance in the display
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 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

REPLACING THE FUSES
WARNING: To avoid electric shock, disconnect the test
leads from any source of voltage before removing the fuse
cover.

11
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.
4. Remove the four “A” screws securing the rear cover.
5. Lift the center circuit board straight up from the
connectors to gain access to the fuse holders.
6. Gently remove the old fuse and install the new fuse into
the holder.
7. Always use a fuse of the proper size and value
(0.2A/250V fast blow for the 200mA range).
8. Align the center board with the connectors and gently
press into place.
9. Replace and secure the rear cover, battery and battery
cover.
Multi-Network Modular Cable Tester Operation
Note: Make sure the battery power is sufficient. Insufficient
battery power will lead to dimmed LEDs and incorrect
results.
10 Base-T Test
1. Plug one end of the tested cable into the transmitting RJ45
jack on the master unit marked with a ' 回' and the other
end of the cable into the remaining receiving RJ45 jack.
2. Slide power switch on. The upper row of LEDs will start to
scan in sequence if the Auto/Manual button is set on
"Auto" mode. The LED for pin 1 will light up if the button is
in "Manual" mode.
3. Switch back and forth from Auto or Manual scanning mode
by pressing the Auto/Manual button on the side of the

12
master-testing unit.
4. Once both ends of the cable are plugged in properly, the
second row of LEDs will illuminate according to the
corresponding LEDs in the top row.
5. Read the results of the LED display for the pin
configuration status of the tested cable. If you fail to read
the results the first time inAuto mode, you may wait for the
second LED scan, or simply switch to Manual mode for pin
by pin testing. In Manual mode, pressing the square "Test"
button will advance testing to the next pin.
RJ11 Modular Cable Test
Please follow directions for the UTP/STP Cable Test anduse
the operations manual for the correct LED pin out display
Coaxial Cable Test
1.Plug the two attached BNC adapter cables on both RJ45
jacks. Then connect the tested cable to each end of the
BNC adapter cables
2. For the remaining testing procedures, please refer to
10Base-T Test steps 2 to 5.
Note:
1. The center pin of BNC should be read on LED 2.
2. As Coaxial cable has only two wires, we suggest you read
the result of the LED scan using Manual mode.
Remote Test
1. Plug one end of the tested cable to the transmitting RJ45
jack on the master unit marked with a ' ' and plug the other
end into the remote terminator. If the tested cable is
installed in a patch panel or wall plate, you may use the
included patch cable to solve the connector gender
problem.

13
2. Now, set the Auto/Manual switch to Auto mode for
one-persontesting.
3. Read the test results from the LED display on remote
terminator.
Note: The LED display on the remote unit will scan in
sequencecorresponding to the transmitting end of the
master unit.
