7.4. Calibration Errors
When an error occurs during calibration, the error number is displayed.
If calibration is finished without releasing the error, the setting values will be restored to
the state before calibration.

capacity / minimum division) exceeds
the specified value.
Voltage at zero calibration exceeds in
the positive direction.
Voltage at zero calibration exceeds in
the negative direction.
The value of the calibration weight
exceeds the weighing capacity.
The value of the calibration weight is
less than the minimum division.
The load cell sensitivity is not sufficient.
The load cell output voltage is too high
when the load of the weighing capacity
is placed.
Voltage at span calibration is less than
voltage at the zero point.

Remedy
Make the minimum division
greater or make the
weighing capacity smaller.
The specified value
depends on the instrument
or specifications.
Check the load cell rating
and connection.
When nothing is wrong with
the rating and connection,
adjust the load cell output
as described in the next
section.
When the load cell or A/D
converter may be the cause
of error, confirm it by using
the check mode.
Use an appropriate
calibration weight and
calibrate again.
Use a load cell with higher
sensitivity
or
make
minimum division greater.
Use a load cell with a
greater rating or make the
weighing capacity smaller.
Check
the
load
connection.
