R Reference point of measurement
D Distance
L Level
E Empty calibration (= zero point)
F Full calibration (= span)
If the ε value is lower than 7 in the case of rope probes, measurement is not possible
r
in the area of the tensioning weight. The empty calibration E should not exceed LN -
250 mm (LN - 10 in) in these cases.
1. Setup → Device tag
