Calibration using online setting
NOTICE!
Interference in function
Changing the transducer output signal may result in
personal injury and equipment damage if the system is
ready for operation.
Ź Persons must keep away from the system's
hazardous zones.
In online setting the system is not shut down. The start and
end values are set online.
Maximum setting range for each calibration
procedure:
Start value: ±25% of present stroke
End value: ±25% of present output value
If the desired value cannot be attained in the first
calibration procedure (max. setting range exceeded), the
calibration procedure must be started again.
