(Calibration error)
Inditial dead load 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.
If still displayed, connect a resistor between -EXC and -SIG load cell connections. This
should shift the zero point. Do Zero Calibration again.
(Calibration error)
The Balance Weight Value is larger than the Capacity.
Re-enter the Balance Weight Value equal to or less than the Capacity.
Do Span Calibration again.
The relationship between Capacity and Balance Weight Value
Balance Weight Value must be between 50% to 100% of Capacity in order to do Span Calibration
correctly.
(Calibration error)
The set Balance Weight Value is “00000”. Set adequate value to Balance Weight Value.
(Calibration error)
T
he load cell output dose not reach the span adjustment range of the F701-C.
Check how load is applied to load cell; check load cell has sufficient outpul (mV/V) to reach span
range. Do Span Calibration again.
Or, when an equivalent calibration is done by resolution that exceeds 1/10000, it is assumed the one
not reaching within the range of the span adjustment.
