6. Troubleshooting
If a transducer fails to read, the following steps should be taken
1. Check the coil resistance. Nominal coil resistance is 180
Ω
±
10 plus cable resistance
(22 gage copper = approximately 20
Ω
per 1000 feet).
a) If the resistance is high or infinite, a cut cable must be suspected.
b) If the resistance is low or near zero, a short must be suspected.
c) If resistances are within nominal and no readings are obtainable on any transducer, the readout is
suspect
and the factory should be consulted.
d) If all resistances are within nominal and no readings are obtainable on any transducer, the readout is
suspect and the factory should be consulted.
2. If cuts or shorts are located, the cable may be splices in accordance with recommended procedures.
