PROBLEM PROBABLE FAULT LOCATION
NaviTrack® II locks up
during use. Turn the unit off, and then back on. Remove the batteries if the unit will not turn off. If batteries are
low, replace them.
While tracing, lines are
“jumping” all over the
screen in the mapping
display. This indicates that the NaviTrack® II is not picking up the signal or there is interference.
Make sure that the transmitter is well connected and grounded. Point the NaviTrack® II at either
lead to be sure that there is a complete circuit.
Try a higher frequency, or connecting to a different point in the line, or switching to inductive
mode.
Try to determine the source of any noise and eliminate it. (Bonded grounding, etc.)
While locating a sonde,
lines are “jumping” all
over the screen. Check the batteries in the sonde to see that they are working.
Sonde may be too far away; try starting with it closer in if possible, or do an area search.
Verify signal by placing lower antenna close to sonde.
NOTE – Sondes have difficulty emitting signals through cast iron and ductile iron lines.
Distance between sonde
and either Pole is not
equal. Sonde may be tilted or there may be a cast iron to plastic transition.
Unit acts erratic, won’t
power down. Batteries may be low. Replace with fresh batteries and turn on.
Display appears
completely dark, or
completely light when it
is turned on. Power the unit off and then back on.
Adjust the LCD screen contrast.
There is no sound. Adjust the sound level in the sound menu.
NaviTrack® II will not pick
up the signal. Check that the correct mode and frequency is set. Examine circuit for possible improvements.
Relocate transmitter, change grounding, frequency, etc.
NaviTrack® II will not turn
on. Check orientation of batteries.
Check that the batteries are charged.
Check to see that the battery contacts are OK.
Unit may have blown a fuse. (Factory service is required.)
