6.3 Shortening of the probe
6.3.1 How to shorten the rod and to 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 100 mm (L
min
)! The unit does not support probe lengths
below 100 mm� If shorter probes are used, measurement errors can occur�
Proceed as follows:
►
Screw the probe 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 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�
6.3.2 Shortening of the coaxial pipe
The coaxial pipe and the rod must be of the same end length:
