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 trans-
mitter, change grounding, frequency, etc.; modify Proximity Threshold (page 24) and/or Signal Focus Control
settings (page 24).
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).
