Probe type
The transmitter is designed to optimize measurement performance for each probe type.
The transmitter automatically makes an initial calibration based on the type of probe that
is used.
This parameter is pre-configured at factory and only needs to be set if the probe is
changed to another type, or if you have installed a spare transmitter.
Select the type of probe that is mounted to the transmitter. Select User Defined probe if
your probe can not be found in the list or if you have done modifications to a standard
probe.
Probe length
The probe length is the distance between the Upper Reference Point and the end of the
probe. If a weight is used at the end of the probe it shall be included.
For flexible single lead probes anchored with chuck, the Probe Length should be
configured as the distance from the Upper Reference Point to the top of the chuck.
This parameter is pre-configured at factory. The probe length must be changed if the
probe is shortened, or if you have ordered a spare transmitter head.
