2. Safetyand operational precautions
2.1 Warnings
Ø Never connect the test equipment to an active network.
Ø Service is allowedto be carried out onlybyan authorised person!
Ø Use onlystandard or optional test accessories supplied byMetrel!
Ø Use onlyconnector types equivalent to those built in to avoid damage to the
instrument components.
Ø If the test equipment is used in amanner not specified in thisUsers Manual,
the protection provided bythe equipment maybe impaired!
2.2 Batteryreplacement
Note
• Insert cells correctly, otherwise the instrument will not operate and the batteries
could be discharged.
• If the instrument is not to be used for a long period of time, remove all batteries from
the batterycompartment.
• Batterycompartment is protected with a fuse to prevent abnormal use ofbattery.
• External charger is not intended for supplying the instrument without batteries.
Warnings
Ø Do not charge alkaline batteries.
Ø Use onlychargers delivered from Metrel or distributor of the test equipment to
avoid possible fire orelectric shock.
Ø In case of blown fuse consult your distributor.
2.3 Service and recalibration
It is essential that test instrument is regularlycalibrated in order technical specification
listed in this Instruction Manual to be guaranted. We recommend the calibration to be
carried out once per 2 years.
Metrel encloses to everynewinstrument an original calibration certificate.
For recalibration and repairs under or out of warrantytime please contact your
distributor for further information.

Additional error sources that must be considered when measuring length:
UncertainityofNVP (nominal propagation speed)
Pulse attenuation at high frequencies effects the accuracyat long distances(over

10. Fast test
The Fast Test function enables fast and convenient checking ofthe installation. Its main
advantage is that the test can be performed byone person, without using the Remotes.
Most likelyconnectivity faults like bad contacted connector and shorts between wires
can be found with Fast Test. The cable length is also reported, together with the
distance to eventual problems.
We recommend to use this test for fast connectivitychecks during bulding ofthe
installation.
For thorough cable connectivitytests the Complete Test should be used.
For thorough cable qualitytests the Length&Reflections function should be used.
Typical Cable Scannerconnectionsin Fast Test
Test procedure
1. Select Fast Test with rotaryswitch.
2. Checkthe selected cable type and pin configuration (refer to chapter 8 for more
information), Connect the cable under test to the instrument and press .
If the test passed succesfullyfollowing items
are displayed:
- the sign
- the cable length
- correctlyconnected wires

If one or more faults are detected following
items are displayed:
- the and signs
- correctlyconnected pairs
- length ifavailable (depends on the kind of
the fault)
test failed, wires 5,1,2,3,6,7 correctlyconnected
The related wires, type and distance to fault
(ifavailable) can be viewed byusing and
keys. During displaying faults the sign
is displayed.
test failed, shorted wires 4 and 8 at 2.2m
If the test passed succesfullyon the cable
pairs defined in selected Cable Type but
other connections were found that are not in
accordance with the defined cable type
following items are displayed:
- the and signs
- the cable length
- correctlyconnected pairs
test conditionallypassed, unselected connected
wires detected
The redundant wire and pairs connections
can be viewed byusing and keys.
During displaying them the sign is
displayed.
test conditionallypassed(shorted wires 4and 8 at
2.2m.The wires arenotdetermined in the selected
cable type)
test conditionallypassed (Pair 4 is connected. The
pair is not determined inthe selected cable type)
Note:
The Fast Test is considered to be performed on cables opened at the far end. Ifthe
cable is terminated bya hub the termination is detected and displayed asa fault.
If a Remote is connected at the far cable end Remote is displayed and the test is not
performed.
Fast Test is not applicable when BNC output is selected.
Broken wires (inside the length tolerances) close to the the far end can't be detected
with this test.
Length can't be measured on terminated cables.

11. Complete test
Complete test checks the installation against all possible connectivityfaults. Beside the
complete connectivitytest the cable identification and cable lenght are performed.
Remote units must be connected to the far cable end while performing Complete Tests.
We recommend to use this test after the installation is built and before certifying it.
For thorough cable qualitytests the Length & Reflections function should be used.
Typical Cable Scanner connections in Complete Test
Test procedure
1. Select Complete Test with rotaryswitch.
2. Checkthe selected cable type and pin configuration (refer to chapter 8 for more
information). One ofthe Remote Units must be connected at the far cable end.
Connect the cable under test to the instrument and press .
If the test passed succesfullyfollowing items
are displayed:
- the sign
- the identification number
- correctlyconnected wires

With the keyit can be switched between length and identification number (if
available).
If one or more faults are detected following
items are displayed:
- the and signs
- correctlyconnected pairs
- the identification number ifavailable

If the test passed succesfullybut additional
connections were detected that are not
defined in the set Cable Type following
items are displayed:
- the and signs
- the identification number ifavailable
- pairs connected according to the set type
test conditionallypassed, unselected connected
wires 1,2,3,6detected

The redundant wire and pairs connections
can be viewed byusing and keys.
During displaying them the sign is
displayed.
test conditionallypassed (pair 2 is connected. The
pair is not determined inthe selected cable type)
Note:
If no Remote Unit is connected at the far cable end ?Remote is displayed.
Remotes #1 - #5 are applicable on all cable types.
Remotes #6 - #15 are applicable onlyon cables where all 4 pairs are used.
Complete Test is not applicable when BNC output is selected.

12. Length and reflections
This function enables accurate cable length and qualitymeasurements. Up to 3 largest
reflections caused bycable damages, impedance mismatchesor other reasons are also
detected.
There are manyapplications where the Length & Reflection test can be used
- checking newcables against possible damages
- checking cable lengths
- determining location ofcable problems (broken, shorted, damaged cable)
- checking connection and junction points quality
The in built Time Domain Reflektometer provides the distance and amplitude
information of
reflected pulses. That helps to determine the reason ofcable problem.
Typical Cable Scannerconnectionsin Length & Reflections Test
Amplitude information
The amplitude ofthe reflected pulses is available as a subresult providing important
information about the cause ofproblem (exessive attenuation, shorted or open end,
improper termination, unproper connector assembling etc) – see pictures below.
100% equals the amplitude ofthe pulse at the output connector into a 100ΩUTP Cat 5
cable.
Pulse length, reflections
Due to cable attenuation along the cable the reflected pulse weakens when the distance
increases.
Three pulse lenghts are used to compensate for the cable attenuation.
Special algorithms are used to evaluate the 3 largest reflections regardless ofthe pulse
energyand to differ between length and reflections.
