7. Calibration

7.1. General Description

In the calibration mode, the operation to relate the output voltage from a load cell to the

mass value and other operations directly related to weighing are performed.

Calibration with an

actual load

Calibration is performed using a calibration weight.

• Zero calibration: Adjusts the indicator so that the

measured value will be zero when no

load is applied to the load cell.

• Span calibration: Enter the calibration weight value and

place the calibration weight on the load

cell.

When the indicator enters the mode of calibration with an

actual load, the tare weight and the zero value will be

automatically cleared.

Calibration-related

function

Setting basic constant values of the indicator such as the

minimum division and weighing capacity and other data

directly related to weighing is performed.

Setting the parameters for digital span calibration is also

performed.

Digital span

Calibration is performed without an actual load, by keying in

the load cell output voltage (mV/V).

• Input voltage at zero: Key in the load cell output at zero.

• Input voltage at span: Key in the load cell output at span.

(Load cell output at full capacity – load cell output at zero)

• Calibration weight value at span:

Key in the calibration weight value

corresponding to the input voltage at

span.

(The input voltage at span is related to the mass value.)

All data initialization

Clears all the data in the EEPROM and battery backup

RAM.

NOTE: All the data set in the calibration mode is stored in the EEPROM and is

maintained regardless of battery condition.
