TROUBLESHOOTING
Table 3 is intended to serve as an aid in locating the
cause of a malfunction.
The transmitter is not designed to be repaired in the
field. If a problem should develop, first check for proper
wiring, calibration and sensor sensitivity. If it is
determined that the problem is caused by an electrical
malfunction in the transmitter, the unit must be returned
to the factory for repair.
