6.3 Shortening of the probe
The probe can be shortened to adapt to different tank heights� In that case, not
only the probe but also the coaxial pipe needs to be shortened�
6.3.1 How to shorten the probe and to determine its length
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�
►
Screw the probe to the unit�
►
Mark the desired length (L) on the probe� The
reference point is the lower edge of the process
connection�
►
Remove the probe from the unit�
►
Shorten the probe at the mark�
►
Remove all burrs and sharp edges�
►
Screw the probe 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
