Maximum measured error
Typical statements for reference conditions:
DIN EN 61298-2, percentage of the span.
Output: digital
sum of non-linearity, measurig range:
non-repeatability – up to 10 m: ±3 mm
and hysteresis – > 10 m: ± 0.03 %
for PA coated rope
measuring range:
– up to 5 m: ±5 mm
– > 5 m: ± 0.1 %
Offset / Zero ±4 mm
If the reference conditions are not met, the offset/zero arising from the mounting situation may be
up to ±12 mm. This additional offset/zero can be compensated for by entering a correction
(function "offset" (057)) during commissioning.
Differing from this , the following measuring error is present in the vicinity of the probe end:

Note!
Please reenter the blocking distance in the function group "extended calibr." (05) function
"upper block.dist" (059) when installing the device in a high nozzle: upper blocking distance (UB)
= nozzle height (H) + 50 mm.
