12.TROUBLE SHOOTING

(Calibration error)
Load cell output is negative.
Check that load cell is mounted in the correct direction; check that load is being applied to the load
cell in the correct direction; check that the +SIG and -SIG lines are propely connected. Do Span
Calibration again.
(Calibration error)
Load cell output is beyond span adjustment range of the F701-C.
Check how load is applied to load cell; check load cell has sufficient output (mV/V) to reach span
range. Do Span Calibration again.
(Calibration error)
The load is not stable enough for correct Calibration.
Adjust the stable period and stable range of Motion Detection so “
” display lights during
Calibration. Do Calibration again.
STAB
The span adjustable range of the F701-C is 0.3 ~ 3.2 (mV/V).
Since display to the Capacity is guaranteed in Span Calibration, calibration
cannot be performed if the load cell output is under 0.3 (mV/V) (
) or
exceeds 3.2 (mV/V) (
) when the Capacity is reached.
