7.1
Diagnosis and Rectification of Faults
The following chart lists typical causes of faults and meth-
ods of rectification. Please contact your Kistler distributor if
you cannot rectify a fault.
Fault Cause
Rectification
Signal cable interrupted
Check measurement setup (connec-
tions and cables).
Charge amplifier faulty
Check charge amplifier for fault as
described in the instruction manual
Charge amplifier not in Measure
mode
Check charge amplifier for fault as
described in the instruction manual
No measurement signal at the
output of the charge amplifier
Press Force Sensor faulty
Have repaired in the manufacturer's
factory. See Section 7.2 for proce-
dure
Quasistatic measurements
not possible (pronounced
signal drift)
Insulation resistance of measuring
chain poor
Adopt a step-by-step approach to
diagnose the cause of the fault;
check drift with the sensor input on
the measuring instrument open or
shielded; Check insulation resistance
of the individual components with the
insulation tester Type 5493. Clean
connector
Charge amplifier reaches limit
during measurement
Force to be measured too large
for the chosen measuring range.
Select a larger measuring range on
the charge amplifier.
Input stage of the measuring in-
strument malfunctioning.
Replace MOS-FET or operational am-
plifier of the input stage of the meas-
uring instrument.
