RXMT = 1335.6 Ohms
Transmit Test Results = $40 ... PASS
d. Observe the RXMT values. They should be above 1300 ohms with
the transducer disconnected.
e. Re-connect the transducer to the electronic housing by connecting the
transducer cable.
f. Type
PT4
. A message similar to the following should appear.

g. Observe the RXMT values. They should be approximately 109 ohms
with the transducer connected.
5-4.4 Sensor Test
This test checks the internal ADFM sensors (temperature and depth).
a. Start BBTALK . Press the
End
key to wake the ADFM.
b. Type
CP
to clear the fault log.
