INTRODUCTION
The TIS 880 tester Is a small hand-held
cable tester, which enable network
professionals to quickly and easily verify
the integrity of straight-through, twisted
pair cables and coaxial cables. In addition,
the TIS 880 can test the ID number of the
ID test terminal connected to the remote
end of the cable under test so that this
cable can be verified.
Features
1. Tests UTP (Unshielded Twisted Pair),
STP (Shielded Twisted Pair) cable and
coaxial cable.
2
2. Checks continuity and configuration of
wiring with RJ45 plugs.
3. Tests for open circuits, shorts, miswires,
reversals, and split pairs.
4. Shield detection tests a cable's shield
integrity.
5. Debug mode quickly identifies which
cable pairs have a specific wiring fault.
6. Main unit and Remote unit allow one
person to test T568A, T568B,
10Base-T, and Token Ring cables.
7. Main unit is powered by two 1.5V
batteries and remote unit does not need
battery.
8. Low battery indication

Removing the Remote Unit:
Before remote test, you must remove the
Remote Unit from the Main Unit. To do it,
hold the Main Unit with a hand, use another
hand to hold the Remote Unit and slide it
upwards or downwards.
Slide the Remote
Unit upwards or
downwards.

TYPICAL FAULTS
For straight-through cable or cross-over
cable tests, the tester has two operating
modes: Test mode and Debug mode.
In Test mode, a flashing pair LED indicates
that this wire pair has a fault, meanwhile a
fault indicator LED lights up to indicate
which fault was detected. Multiple flashing
pair LEDs indicate multiple pairs and/or
multiple faults. In this situation, you should
use Debug mode to diagnose the faults in
more detail. Correct the faults until the
cable is verified be to be correct by using
the tester.
A short circuit condition exists.

Note:
For some types of cables, so called
" OPEN " is not an abnormal condition.
Therefore the tester does not an " OPEN "
indicator LED. Open is displayed as an
unlit pair or shield LED when the tester
shows the test result. The user should
determine if a wire is present and
continuous or OPEN by comparing the
illuminated pair and/or shield LEDs with
the expected number of wires (of the cable)
that should be good.
During test, if the " LOW BATT " LED lights
up, the batteries in the Main Unit are low.
To avoid possible wrong test result, replace
the batteries immediately.
NOTICE PRIOR TO USE
1. Before using the tester, disconnect the
conductor) and ring (negative conductor)
of two twisted pairs are interchanged.
