Changing the Probe
1. Loosen the nut.
2. Remove the transmitter head from the old probe.
3. On the new probe, make sure that the protection plug is removed and the
upper surface of the Process Seal is clean. Also make sure that the
spring-loaded pin at the center of the Process Seal is properly inserted.
4. Mount the transmitter head on the new probe.
5. Fasten the nut again.
6. If the new probe is not of the same type as the old one, update the
transmitter configuration by setting the Probe Type parameter to the
appropriate value:
HART Fast Key sequence [1, 3, 2, 3],
or
RCT Setup/Tank Config.
7. Measure the probe length and enter the measured value:
HART Fast Key sequence [1, 3, 2, 2],
or
RCT Setup/Tank Config.
8. Verify that the transmitter is calibrated.
NOTE
Flexible and Rigid probes require different radar electronics and can not be
used with the same transmitter head.
