If you suspect a malfunction, refer to Table 4-1 to verify that
transmitter hardware and process connections are in good working
order. Under each of the seven major symptoms, you will find specific
suggestions for solving the problem. Always deal with the most likely
and easiest-to-check conditions first.
TROUBLESHOOTING
This section offers tips for troubleshooting several kinds of potential
malfunctions. To determine a malfunction, use pin-like probes to break
through the protective coating to make measurements on a circuit
board.

parts can affect product performance and the output signal
used to control a process, and may render the instrument
dangerous. Direct any questions concerning these
