• The fixing must be either reliably grounded or reliably insulated. If it is not possible to
mount the probe weight with a reliably insulated connection, it can be secured using an
isolated eyelet, which is available as an accessory.
• In the case of a grounded fixing the search for a positive end-of-probe signal must be
activated. Otherwise an automatic probe length correction is impossible.
