5.0 Troubleshooting
guide
5.1 Electrical
faults
When the battery symbol is permanently illuminated on the display, a reliable reading
can no longer be guaranteed. The gripping force meter must be recharged. It is possible
to use the meter while recharging, however this lengthens recharging time.
The display and
sign begin to flash when the gripping force meter is exposed to a
load of greater than 100% of the maximum value. Overloading up to 120% of the maxi-
mum is of no consequence to the meter. If the gripping force falls below 100% again,
the meter returns to normal display mode again.
By overloading greater than 120%, the reading value is no longer
displayed. The
sign continues to flash. A critical overload limit
has been reached which, under certain circumstances, may lead to
lasting distortion of the measuring bolts. This causes displacement
of the zero-point.
If the zero-point has been displaced more than once by previous
overloading, a further overload of less than 120% may lead to the
display being shut off. Again this is shown by the flashing
sign
The gripping force meter automatically carries out an adjustment of the zero-point when
it is switched on. If the zero-point has been displaced by more than 20% of the maxi-
mum measuring range value the display flashes. This indicates previous mechanical
overloading of the gripping force meter and lasting distortion of the measuring bolt. In
this case, the meter should be returned to FORKARDT for testing and repair.
5.2 Mechanical
damage
The SKM 1200 and SKM 1500 gripping force meters are robustly constructed. Should
the unit, however, have been damaged in any way, it should be returned for testing and
repair.
Worn or lost tension and compression bolts may be re-ordered from FORKARDT as fol-
lows:
SKM 1200
set of tension and compression bolts
Ident-No. 300224003
SKM 1500
set of tension and compression bolts
Ident-No. 300229003
