7.3 Shortening of the probe, determination of the probe length

7.3.1 Shortening of the rod

The rod can be shortened to adapt the probe to different tank heights�

Ensure that the probe length is not below the minimum permissible probe length of 150 mm (L min

)� The unit does not support probe lengths below
