¶
In order to check the correct functioning of the
potentiometer, pull out the gauge and check that
during the stroke the value does not get blocked.
!
You need to check the values of the potentiometers
when you insert the measures and the machine
shows unacceptable values and when the problem
persists even after the calibration.
Diagnosis distance potentiometer (4)
Defect
The value remains blocked
at scale end or between 0
and 40.
The value remains blocked
between 40 and 4095.
The value starts from
ex.1500 and blocks at the
end of the scale.
!
After having replaced the potentiometer or after
having detected that the fastening screw is loose,
before proceeding with calibration, follow the
instructions reported here.

potentiometer disconnects from the shaft, the
machine will no longer read any measure because
the carriage of the potentiometer remains at the
end of the stroke. So, follow the instructions for
"positioning diameter potentiometer".

By pressing the <DIAMETER> key and the + key,
the L00P function activates, making it possible to
perform a resistance test: the machine will perform
a launch every 60 sec and, should a difference above
5 g be detected compared to first measurement
cycle, it will lock in automatic highlighting the
wording Err0.
