5-4 CALIBRATION ERRORS

Err

messages

Causes Solutions

CErr 0

The minimum graduation is other than 1, 2, 5,

10, 20, and 50.

Confirm setting of the minimum graduation, CALF-03.

CErr 1

Resolution (weighing capacity/minimum

graduation) is more than 16000.

Confirm the relations between the weighing capacity, CALF-04, and

minimum graduation, CALF-03.

CErr 2

The voltage of the zero calibration point is

overloaded in the positive direction.

CErr 3

The voltage of the zero calibrated point is

overloaded in the negative direction.

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 10-1 to verify the problem.

CErr 4

The calibration weight is more than the weighing

capacity.

CErr 5

The calibration weight is less than the minimum

graduation

Calibrate with the proper calibration weights.

CErr 6 Sensitivity of the load cell is insufficient.

CErr 8

The output voltage of the load cell is too high

with the span capacity loaded,

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.

• Reset CALF-04.

• Set CALF-16 to “3.200000 “.

• Set CALF-17 to the capacity weight.

CErr 7

The voltage of the span calibration point is

negative with respect to the zero point.

Confirm the connection of the load cell.

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.

5-5 INITIALIZATION OF ALL THE DATA

This is to initialize all the data of the EEPROM and RAM. Therefore, the calibration data and general function data are

also initialized. For the details, see 10-2.
