1 Introduction

The TM-902/TM-903 Multimedia Cable
Tester (TM-901N LAN Cable Tester)is a
hand-held test instrument that lets you verify
and troubleshoot the Lan cable of twisted
pair.

2 Safety Precaution

CAUTION

Be extremely careful for the
following conditions while measuring

 Do not operate the meter under the

environment with explosive gas (material),
combustible gas (material) steam or filled
with dust.

 In order to avoid reading incorrect data,

please replace the battery immediately
when the symbol “ ” appears on the
LCD.

 In order to avoid the damage caused by

contamination or static electricity, do not
touch the circuit board before you take
any adequate action.

 Operating Environment: Indoors use. This

instrument has been designed for being

1

TM-901N/TM-902/TM-903

used in an environment of pollution
degree 2.

 Operation Altitude: Up to 2000M.
 EMC: EN61326-1(2006),

IEC 61000-4-2(2008,
IEC 61000-4-3(2006) + (2007).

3 The verifier does the following:

 Detects opens, shorts, miswires and split

pairs on twisted pair cabling.

 Displays graph wiremap , opens, shorts,

miswires, split pairs, and the remote ID
number all on one screen.

 Identify remote ID number only one pair.
 Measures length.
 Using multiple remote ID up to 8 locators.
 Low battery detector “ ”.
 Auto backlight.
 Auto power off.

6 Testing Twisted Pair Cabling

1. Connect the meter and remote ID locator
to the cabling as shown in Figures.

2. Press the key to power on.

(TM-902/903)

3. Press key to measures wiremap and

Remote ID Locators detect.

4. Display show some testing option as

shown in Figures.

7 Twisted Pair Test Results

The following figures show typical test results
for twisted pair cabling. Any error occurs will
show symbol on LCD.

Opens

Figure shows an open pair wire 4 and 5.

6

TM-901N/TM-902/TM-903

Shorts

Figure shows tow short between wires 3, 4
and 5, another 1 and 8.

※ When shorted occur, the verifier maybe

not show open and miswires.

Miswires

Figure shows that wires 3 and 4 are crossed.
The pin numbers order to indicate the fault.

7

TM-901N/TM-902/TM-903

Split Pair

The following figure shows a split pair on 3, 6
and 4, 5. The split pair flashes to indicate the
fault. LCD will show “SPLIT” indicate.
In a split pair, continuity from end to end is
correct, but is made with wires from different
pairs. Split pairs cause excessive crosstalk
that interferes with network operation.

※ The spilt pair detects of cable must be at

least 5 meters (15ft) in length.

※ If one of open, short or miswires occurs,

the spilt pair detects won’t work.
