PROBLEM
SR-20 locks up during
use.
SR-20 will not pick up
the signal.
While tracing, lines are
"jumping" all over the
screen in the mapping
display.
While locating a Sonde,
lines are "jumping" all
over the screen.
Distance between Sonde
and either Pole is not
equal.
Unit acts erratic, won't
power down.
Display appears
completely dark, or
completely light when
it is turned on.
There is no sound.
SR-20 will not power on.

PROBABLE FAULT LOCATION
Power the unit off, and then back on. Remove the batteries if the unit will not switch off.
If batteries are low, replace them.
Check that the correct mode and frequency is set. Examine circuit for possible improvements.
Relocate transmitter, change grounding, frequency, etc.; modify Proximity Threshold (page 22)
and/or Signal Focus Control settings (page 22).
This indicates that the SR-20 is not picking up the signal or there is interference.
Make sure that the transmitter is well connected and grounded. Point the SR-20 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.)
Check SR-20 batteries are fresh and fully charged.
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.
Increase Proximity Threshold and try lower settings of Signal Focus Control to improve "focus" on
weaker signals.
Sonde may be tilted or there may be a cast-iron-to-plastic transition.
Batteries may be low. Replace with fresh batteries and power on.
Power the unit off and then back on.
Adjust the LCD screen contrast.
Adjust the sound level in the sound menu. Verify Proximity Signal is greater than zero.
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.)
