If Something Seems Wrong
with the Tester
The display remains at
8888
after power on.
The self test has failed. The batteries may be weak or
the tester has water inside. Try changing the batteries
or drying the tester.
The tester reads less than 10 feet (3 meters)
regardless of the length of the cable.
The connection to the cable is broken. Check your
connection to the cable for dirt or insulation. Also, test
the clip leads by shorting them and listening for the
beeper. You can also visually check the center
connection of the BNC for damage.
The tester does not respond to any key presses.
The batteries could be dead or inserted incorrectly, or
the contacts are dirty or broken. Please ensure that
nothing is connected to the input connector before
opening the battery door, and then check the battery
installation. Remove the batteries and check the
contacts for dirt or damage. Please observe correct
polarity when inserting the batteries.
Maintenance
Warning
To avoid possible fire, electric shock or
personal injury:
Do not open the case. You cannot repair or replace
parts in the case. If you open the case, you can
cause damage to the circuits in the tester.
Use only service centers that are approved by Fluke
Networks.
Before you do any maintenance procedure,
disconnect the test clips from the cable or circuit.
Do not use the tester if it is wet. Do not apply
heat to the tester to make it dry more quickly.
Batteries contain hazardous chemicals that can
explode or cause burns. If these chemicals touch
you, immediately clean the area with water and
get medical aid.
Caution
To prevent damage to the tester caused by
battery leakage, remove the batteries if you
will not use the tester for a long period.
Note
Opening the housing will void the warranty.
If the Tester Gets Wet
Moisture will not harm the tester. However, moisture
can provide a leakage path that may conduct
hazardous voltages to you.
If moisture gets inside the tester, let the tester dry at
normal room temperature for 24 hours.
