TROUBLESHOOTING
Do not attempt to repair the digital depth
gauge yourself. There are no user
serviceable parts inside, and special tools
and techniques are required for reassembly
to ensure the waterproof integrity of the
housing.
Repairs should be performed only by
authorized technicians.
Many requests for repair received by Teleflex
involve units that do not actually need repair.
These units are returned “no problem found”. If
you have a problem with your digital depth
gauge, consult the following troubleshooting
guide before calling Customer Support or
sending your unit in for repair.
1. Nothing happens when I turn the unit on.
Check the power cable connection at both ends.
Be sure that the cable is connected correctly to a
reliable power source—red lead to positive, black
lead to negative or ground. Ensure that the power
available is between 10 and 16 VDC. If the unit is
wired through a fuse panel, ensure that the panel
is powered. Often accessory fuse panels are
controlled by a separate switch or the ignition
switch. Also, often a fuse can appear to be good
when in fact is not. Check the fuse with a tester
or replace it with a fuse known to be good.
