When a centering disk is added to a rod probe, a new probe length must be measured and configured
in the transmitter. Failure to adjust the probe length and the probe termination configurations may
lead to inaccurate readings close to the end of probe or/and may require the user to increase the
blocking distance low. When using a centering disk with a rod probe, the probe length is defined as
the distance from the flange (reference plane) to the top of the disk as shown in Figure 3-20: Probe
length definition for rod probes using a centering disk. When using a wire probe, the probe length is
independent of whether a centering disk is present or not as the probe length is defined as the distance
from the flange (reference plane) to the top of the end weight.
