F.4 Troubleshooting
Below are some commonly experienced problems along with possible remedial action. Contact
the factory if any problem remains unresolved or additional help is required.
Symptom: A particular channel on the multiplexer appears to be malfunctioning:
 Check sensor connections on the terminal board. Clean if corrosion exists.
 Try moving the sensor wired to the suspect channel to another channel to verify the
malfunctioning of the channel (as opposed to the sensor).
Symptom: No channels are working:
 Inspect circuit board for shorts, opens, or other damage.
 Is moisture present on circuit board? If so, install desiccant to absorb.
Symptom: Channel selection appears to be random:
 Has corrosion built up on the circuit board? Clean if necessary.
 Is there a source of electrical noise nearby? Move multiplexer or noise source if possible.
