Calibration
error 2
The amount of initial tare elimination exceeds the zero adjustment range of
F701+.
Confirm that there is no unnecessary load applied to the load cell.
If an error is displayed while a normal load is applied, connect a resistance
between +EXC and -SIG terminals of the load cell. After shifting the zero
point, zero calibration will need to be re-performed.
Refer to the table below for the relationship between the resistance for
connection and input signal.
Calibration
error 3
The amount of initial tare elimination is on the minus (negative) side. Confirm
that load is applied to the load cell in a correct direction and that the wiring for
load cell +SIG and -SIG are not reversed.
If an error is displayed even with correct load applied and proper wiring,
connect a resistance between -EXC and -SIG terminals of the load cell. After
shifting the zero point, zero calibration will need to be re-performed.
Refer to the table below for the relationship between the resistance for
connection and input signal.
Calibration
error 4
Balance weight value or span calibration value is set higher than capacity. Re-
set balance weight value or capacity, and re-perform span calibration.
In order to perform span calibration correctly, it is recommended to perform it
so that the balance weight value falls between 50% of the capacity and the
capacity.
Calibration
error 5
Balance weight value or span calibration value is set as "00000".
Re-set balance weight value to an appropriate value.
