APPENDIX B: ERROR CODES

Error code
The minimum graduation is other than 1, 2,
"C Err 0"
5, 10, 20, and 50.
Resolution (weighing capacity divided by
"C Err 1"
minimum graduation) is more than 16000.
The voltage of the zero calibration point is
"C Err 2"
overloaded in the positive direction.
The voltage of the zero calibrated point is
"C Err 3"
overloaded in the negative direction.
The calibration weight is more than the
"C Err 4"
weighing capacity.
The calibration weight is less than the
"C Err 5"
minimum division.
"C Err 6"
Sensitivity of the load cell is insufficient.
The output voltage of the load cell is too
"C Err 8"
high with the span capacity loaded
Gravity acceleration rate setting is not
"C Err 9"
correct. (out of the range).
The voltage of the span calibration point is
"C Err 7"
negative with respect to the zero point.
Failed to zero when the power was turned
"ERR St"
on.
Zero was out of the zero valid range when
"Err PZr"
the power was turned on.

Load cell output compensation

Attach a resistor to a place as shown in the picture below to compensate the load cell output.
Use a resistor with as high resistance and low temperature coefficient as possible.
Causes
B-1
Solutions
Confirm setting of the minimum graduation, CALF-03.
Confirm the relations between the weighing capacity
(CALF-04), and minimum division ( CALF-03).
Confirm the rating and connection of the load cell and
see if the load cell is damaged. When the load cell is
connected properly and is not defective, the load cell
output can be corrected by attaching a resistor as
shown below, {Load cell output compensation}.
When it is likely that the load cell or A/D converter is
defective, use the check mode in {9-1. System
check—"Chc Ad"} to verify the problem.
Calibrate with proper calibration weights.
When "C Err 6" or "C Err8" is displayed after CALF-03
(Minimum division setting) and CALF-04 (Capacity
setting) have been set, try to do the following settings
for solution.
•
Reset CALF-03 (minimum division).
•
Reset CALF-04 (capacity).
•
Set CALF-20 (Span input voltage) to "3.200000 ".
•
Set CALF-21 (Weight against Span input voltage)
to the capacity weight.
See {APPENDIX D: Gravity acceleration map} and
set the value again.
Confirm the connection of the load cell.
Confirm the connection of the load cell and around
the load cell.
