6.3 Shortening of the probe
6.3.1 How to shorten the rod and determine its length L
The rod can be shortened to adapt the probe to different tank heights�
Ensure that the probe length is never below the minimum permissible probe
length of 10 cm (L
min
)! The unit does not support probe lengths below 10
cm� If shorter probes are used, measurement errors can occur�
Proceed as follows:
► Screw the rod to the unit�
► Mark the desired length (L) on the rod� The
reference point is the lower edge of the process
connection�
► Remove the rod from the unit�
► Shorten the rod at the mark�
► Remove all burrs and sharp edges�
► Screw the rod to the unit again and tighten it�
Recommended tightening torque: 4 Nm�
► Precisely measure the probe length L, note the
value� It must be entered during parameter setting
of the unit (→ 10.2)�

6.3.2 Shortening of the coaxial pipe
The coaxial pipe and the rod must be of the same end length:
