Faults
Causes
Measures
No display
Leaking of the hydraulic force
measuring unit or pressure
gauge
Visual check whether the
transmission medium has
leaked (glycerine/water
mixture)
Consult the manufacturer
Deviation of the zero point
display
Overload, load offset, defecti-
ve force introduction
Consult the manufacturer
Output signal constant
when changing force
Mechanical overload, defecti-
ve force introduction
Consult the manufacturer
Signal span varies
EMC interference sources in
the environment; for example,
frequency converter
Shield instrument; cable
shield; remove source of
interference
Signal span drops/too small Mechanical overload, leaking
of the hydraulic force measu-
ring unit
Consult the manufacturer
Pointer jerks with force
increase
Stick-Slip effect (internal
pressure too low)
Consult the manufacturer
