There are four functions to be chosen on main menu.
1. WireMap --- Wiring diagram measurement to check end-to
-end con-tinuity of cables M, L, Rand locate errors.(when verify
network cable breaking point, should wire map locally can
identify the breakpoint, don't connect with remote).
2. Pair &Length---Pair and measure length to verify cable
length,open circuit, distance and pairing .
3. Coax/Tel---Coaxial cable and telephone line measurement .
4. SETUP---Calibrate.
Caution:
When testing cable for wiremap with remote,do not
connect over 60V.
Your excellent helper in calile test!

Test Result 1: Short circuit (SHORT)
If there is any short circuit in the cable or terminal, the
display will read as shown to the right (e.g. shows short
circuit between 1and 2).
The tester is incapable of identifying the exact location of the short
circuit.Press the “W[4] ”key to restart testing or press the *:
key to return to the main menu. Always correct short circuit errors
first before beginning further measurements.
Test Result 2:
If the far-end of the cable to be checked does not insert into the
far-end matcher (ID), or the local (L) in local test, the display
will read as shown (right).
NO ADAPTER :
Press the “[Val "key to restart testing or press the “”key to
return to the main menu.
Test Result 3: Normal wiring diagram (WIREMAP) display
The wiring diagram (WIREMAP) will be displayed as shown (right),
ifitis found that the far-end matcher (ID) or the local port (L) on the
far-end of the cable are checked. “R” means remote unit, while “M”
means main tester. (eg:NF-8108)

Wiring diagram (WIREMAP) test function:
After entering the wiring diagram (WIREMAP) test function,
the tester shall carry out wiring diagram (WIREMAP) test and
displays as follows while checking is being undertaken:
—JESTING
18345678. ..
Test Result 4: Wiring diagram (WIREMAP) display when
there is an open circuit at the far-end of the cable.
WIRE MAP: FAIL
R:12X45X78
(ERRREEN]
M:12345678
“R:" line "3" and "6" pins location display "x", this indicates an
open circuit in far-end plug "3" and "6” pins, and that the open
circuit is located nearby the far-end plug.(The open circuit should
be located within 10% of the cable length if it is measured from
the far-end plug)
Note:
As the network cable is made of pair cores, if there is open
circuit, it will show the faults in pairs, just as in the image at the
bottom of page 4, which means an open circuit exists in either
number “3” or number “6” pin, or in both.

Test Result 5:
The wiring diagram (WIREMAP) will display when there is an
open circuit at the near-end of the cable.
It will display the wiring diagram (WIREMAP) as shown (right) if
there is an open circuit at the near-end plug of the cable.
WIRE MAP: FAIL
R:12345678
LLL
M:12X45678
“M:” The “3” pin location displays “X”, which indicates an open
circuit at the near- end plug -“3” pin, and that the open circuit
is located close to the near-end plug. (The open circuit should
be located within 10% of cable length if it is measured from
the near-end plug.)
Test Result 6: Open circuit in the middle of the cable
If there is an open circuit in the middle of the cable, it will
display the wiring diagram (WIREMAP) as shown:
WIRE MAP FAIL |
R:12345678 |
M:123456/8
"|I” The “3” pin location displays “X”, which indicates an open
circuit in the middle of the “3” pin cable.
The open circuit should be located within 10%-90% of cable
length if it is measured from the near-end plug.
For further locating an open circuit, the function* "of
the tester could be used as detailed in the section below.
The display will be as shown (right), indicating that the
measurement is being undertaken
Note: In view of different technical parameters in various
brand cables, the user should apply the tester dynamic
calibration function before length measurement.

Test Result 7: Normal Pair &Length (PAIR &LENGTH) Display
If pair and length measurement is conducted in normal
conditions, it will display as shown.
FAIR 12 100 OM
PRIR 36 108 3M
PAIR 45 1060 2M
FRIK 78 99 BM
When testing cable length, just connect one end of the cable
with the main tester. There is no need for the remote unit.
Press the “[Yl[Al "key to restart testing or press the “[PAIR3L]”
key to return to the main menu.
Test Result 8: Abnormal pair and length (PAIR &LENGTH) display
If there is unpaired lines in the pair and length measurement,
it will display the paired lines first.
PARIR 12 100.0M
PAIR 3b 100. 3M
PAIR 45 1008 2M
78 y
The last line- 78 ¥(right), indicates there is no pairisin lines
7and 8.
It will display the length of unpaired line numbers as shown:
Pil 7 186. 0M
PIN BB9 3M X
A
It will display “X” to indicate an open circuit if the length is less
than 90% of the other line pair length and the open circuit is
located around 89.3m from the tester. (The open circuit line
number could be rechecked by WIREMAP function.)
Note: Cannot check the wiremap of coax cable and telephone
cable directly as it will require an RJ11 cable adaptor and BNC
cable adaptor.

Calibration and Setup
After entering into calibration and setup function, the tester
shall display as shown .
----SETUP----
=2UNIT METER
CAL BRAT |ON
BUIT
Aquick way to enter into dynamic calibration is to hold the
“[PAIR&L]” key while starting the tester.
For an accurate measurement of cable length, the calibration
operation should be completed as follows:
CALIBRATION?
NO YES
After entering into the dynamic calibration function, the display
will be shown on the tester.
Insert the same type of cable of agiven length into port “M”.
You do not need to connect the receiver.
Your excellent helper in cable test!
Press the [Alkey (yes) to undertake measurement and display
the measured length .
PIERSE HBJUST?
20.0M
-OK +
Press and hold the [Al and [Wl key (-/+) to display the length to be
adjusted to the actual given length and then press the“ [PAIR3L]”
key to reserve calibration factor and exit calibration function.
If the cable length being measured is too short (<10m) the
display will remind you to change to alonger cable for
calibration.
Press the [W] key (no) to exit the calibration function. Press
the [al key (yes) to repeat the measurement.
Note: If the tester is restarted after it turns off, it will recover
the standard calibration factor of class UTP5 cable as set up
in manufacturing.

Maintenance
The only field service required for maintaining proper operation is
the periodic replacement of the batteries.
A. Battery Replacement
AWARNING
Before opening the case, remove the test leads from the circuit
and shut off the unit. Failure to observe these warnings can
result in severe injury or death.
B. Cleaning
Periodically wipe with adamp cloth and mild detergent; do not use
abrasives or solvents.
C. Service
Should you need for any reason to return the tester for repair or
