1．Overall description
MT-7025 is a multifunction cable tester. It is a tester that combines
wire tracking, wire finding, cable mapping, and telephone line
polarity test. It can find the target wire in numerous messy wires,
and one doesn’t need to unplug the network cable or turn off the
switching equipment when finding wires. Signal transmission
distance over 2 kilometers. It can be applied on
telecommunications network installation and maintenance.
Compact sizes for carrying convenience, multifunction and easy to
operated, it is a competent tester.

5．Safety instructions
Don’t connect any patch cord when testing telecom cable.
To avoid any possible damage to the meter, please don’t
Always turn the power switch of transmitter off when not in
Please change battery when low battery indication shows up
To avoid battery leakage liquid and damage the meter,
Never test the cable that has over AC 14V or DC10V
to avoid possible electric shock or personal injury and avoid
possible damage the meter or equipment.
Never test a cable without insulation for avoid
possible electric shock or personal injury and to avoid
possible damage the meter or equipment.
Please don’t test on live circuit more than 5 minutes.
open the housing of meter by non- specialized person.
use for power saving.
to ensure correct test result.
please take off battery when not in use for long times.

Power and function switch
TEST: For cable mapping and open/short test.
SCAN: Transmit tone signal for cable finding.
OFF: Power off
Function change button
Power and function switch in “TEST” position:
Press function change button shortly to change scan speed
from either slow or rapid.
Press function change button and hold for 2 seconds, when
“VERIFY” LED change from flash to light up then you can
process the telecom cable open/short test.
Alligator connector clip to 2 wires terminal, it can judge the
resistance is hi or low according to brightness of the number
“1” LED, more bright means low resistance, otherwise, the
5
resistance is high.
Power and function switch in “SCAN” position:
Press function change button shortly for frequency change
from either single or dual frequency signal for cable finding.
Press function change button and hold for 2 seconds, when
“VERIFY” LED lights up then you can take DC level polarity
test. Red Alligator connector clip positive wire and black
connect clip negative wire then “VERIFY” LED turns red, If
reversed the connection then “VERIFY” LED will turn to
green.
Cable mapping indicator
When performing cable mapping or connect to telecom
switching equipment for connection status detection,
number “1” to “8” LED will light up in order. The LED “G”
indicates the shielded conductor is connection or no
connection.

8．How to test
*** Cable map
For testing UTP/STP/SFTP cat.5 cat.5e cat.6 cables and cat.3
telecom cables, connect both side of RJ-45 or RJ-11/12 patch
cord by plug into transmitter and receiver, slide “Power and
function switch” to “TEST” position, the “VERIFY “LED flash,
then star to process cable mapping, press “Function changed
button” to change the scan speed. Cable map and cable
status indication; please refer to below “wire map” for more
detail
Straight: 1~8/S conductors of UTP/STP patch cord are all
connected, both transmitter and receiver 1~8/G LED light up
in order at synchronous. LED “G” indicate shield connection or
no connection.
Crossover: 1~8/S conducts of UTP/STP patch cord are all
connected, both transmitter and receiver 1~8/G LED light up
in order, sequence of receiver 1~8/G indicators light up are not
follow transmitter 1~8/G indicators.
No connection: Part of 1~8/S conductor of UTP/STP patch
cord are not connected, both transmitter and receiver 1~8/G
related LED won’t light up; the other LEDs will light up in order.
Short: 1~8/S conductors of UTP/STP patch cord are all
connected, the transmitter 1~8/G LED light up in order, but
related LED of receiver 1~8/G won’t light up if it is short, the
other will light up in order.
CAT.3 telecom cable map
6P6C: LED 2~7 must light up and the other LED are off.
6P4C: LED 3~6 must light up and the other LED are off.
6P2C: LED 4~5 must light up and the other LED are off.
For CAT.3 telecom cable status indication: crossover、no
connection or short，please refer to WIRE MAP function
instruction.
