LAN CABLE TESTER
Introduction
●The Lan cable tester is a newly designed tool that can
easily test the correct pin configuration of the
RJ45/RJ11 modular cables, 10/100 base-T cable and
Token Ring cable etc.
●By comparing one transmitting end and the
corresponding receiving end, the Lan cable tester
also can test installed cable far away by using the
remote receiving unit.
●The LCT provides the variety for wiring check, such
as cable continuity, open status, short status and
miss- wired.
Features
●Designed for RJ45/RJ11 modular cables, 10/100
base-T cable and Token Ring cable etc.
●The Lan cable tester can verify cable continuity, open,
short circuit and miss-wired.
●The remote receiving unit is available for installed
cables far away either on the wall plates or on the
patch panels.
●Auto and manual scan function.
●Ground wire test.
●Display: LED indication for wire status.
●EN 61010-1 EN 61326-1

Operation
Loopback test
●Plug one end of the testing cable into the RJ45 jack of
sourcing end (OUT) on the master unit and another
end of the testing cable into the RJ45 jack of receiving
end (IN) on the master unit.
●Press the "ON/OFF" button, the master unit will start a
sequential scanning process if the master unit is in
"auto-scanning" mode.
●Press the "ON/OFF" button, the pin1 LED lamps of
the LED indicators will be alight if the master unit is in
"manual-scanning" mode.
Note: When the 9V battery power is low, the testing
results may not be correct. Please replace with a new
9V battery.
●You can choose an auto-scanning mode or a manual-
scanning mode by pressing the "A /M " button.
Remote test
●Plug one end of the testing cable into the RJ45 jack of
sourcing end (OUT) on the master unit and another
end of the testing cable into the RJ45 jack of the
remote receiving unit, then make tests.
●Read the testing results from the LED
indicator on the remote receiving unit.

Button Functions
(1) Function rotary switch
The rotary switch selects the function.
(2) LCD
4000-count LCD with LOW BATTERY indication.
(3) Select Button
For AC/DC function selection.
In the resistance + continuity + diode function, press
the Select button to select resistance, continuity or
diode function.
(4) Range Button
Press the Range button to select the manual range
mode. In manual range mode, each time press
Range button (less than one second), the range
increments and new value is displayed. To exit the
manual range mode and return to auto mode, press
the RANGE button (More than one second).
(5) HOLD Button
Press the HOLD button (HOLD annunciator turns on)
makes the meter stop updating the LCD display. This
mode can be nested in most of the special modes.
Enabling HOLD function in automatic mode makes
the meter switch to manual mode, but the full scale
range remains the same. Hold function can be
cancelled by changing the measurement mode,
pressing range, or push HOLD again.
(6) COM Terminal
This is the ground input terminal. Use the BLACK test
lead to connect.
(7) "+" Terminal
This is positive input terminal for voltage / ohm
measurement. Use the RED test lead to connect.

10
Measurement
(1)Voltage measurement
Insert the BLACK test lead to COM and the RED test
lead to the "+" terminal.
Switch to V function for ACV or DCV
selection. Get the reading directly from the LCD.

11
(2)Resistance Measurement
Switch to OHM range and make sure there is no
power in the circuit being measured. Insert the
BLACK test lead to the COM and the RED test lead
to the "+" terminal.
Connect the test leads to the circuit or device under
test and get the reading directly from the LCD.
(3)Continuity Check
Continuity check shares the same configuration with
400.0Ω manual resistance measurement mode, but
with buzzer output to indicate continuity. The buzzer
generates a 2kHz sound whenever the digit number
less than 25Ω.
Because the cycle time of measurement is only
50ms, the least significant digit will not display.

12
(4)Diode Measurement
Diode measurement mode shares the same
configuration with 4000V manual voltage
measurement mode.
If the test circuit is open or the voltage drop between
the two ports of the device (diode) under test are
larger than 2V, the LCD will show "OL".
The buzzer generates a 2kHz sound whenever the
digit number is less than 0.25V. Because the cycle
time of measurement is only 50ms, the least
significant digit will not display.

Maintenance
(1) Battery replacement
●Lan cable tester :
When press the "ON/
OFF" button to start a
test, if the LED
module of pin-out
indicator is too dark
and can't work
normally, please
replace with a new 9V
battery.
●Multimeter : Replace
two AAA batteries
with the " B" symbol appears at the upper left
hand corner of the LCD.
(2) Cleaning and Storage:
WARNING
To avoid electrical shock or damage to the meter, do
not get water inside the case.
Periodically wipe the case with a damp cloth and
detergent.
Do not use abrasives or solvents.
If the meter is not used for over 60 days, remove the
battery for storage.
