ad?e
The data can not be acquired from
A/D converter.
Repair is required.
eepe
Correct data cannot be read from
EEPROM.
Perform initialization.
If the initialization does not clear the
error, repair is required.
Cale
Calibration data error.
Perform calibration.
C e

Calibration error.
Refer to “
”.
dt?e
A set value is out of range.
Check set values and correct if
necessary.

C?e2
Voltage at zero point calibration
exceeds in the positive direction.
Confirm the rating and connection of
the load cell.
C?e3
Voltage at zero point calibration
exceeds in the negative direction.
C?e4
The value of the calibration weight
exceeds the rated capacity.
Use a proper calibration weight.
C?e5
The value of the calibration weight
is less than the minimum division.
C?e6
The load cell sensitivity is
insufficient.
Confirm the load cell connection.
Use a proper calibration weight.
C?e7
Voltage at span calibration is less
than voltage at the zero point.
Confirm the load cell connection.
C?e8
The load cell output voltage is too
high when loaded to capacity.
Use a load cell with a greater rated
capacity or set a smaller rated
capacity value.
