8. CALIBRATION

Calibration

Calibration using the calibration weight

Calibration test

To check the weighing accuracy, using the calibration weight, and output the result. (Calibration test does not perform calibration.)

Caution

Calibration adjusts the balance for accurate weighing.

Besides periodic calibration and before each use, perform calibration when:

•the balance is installed for the first time.

•the balance has been moved.

•the ambient conditions have changed.

Do not allow vibration or drafts to affect the balance during calibration.

To output the data for GLP using the RS-232C interface, set “GLP output ( info )” of “Data output ( dout )”. For details, refer to “10. FUNCTION TABLE”. Time and date are added to the GLP report. If the time or date is not correct, adjust them. For details, refer to “10-9 Clock and Calendar Function”.

Calibration test is available only when “GLP output ( info )” of “Data output ( dout )” is set to “1” or “2”,

The calibration and calibration test data can be stored in memory. To store them, set “Data memory ( data )” to “3”. For details, refer to “14. DATA MEMORY”.

Caution on using an external calibration weight

The accuracy of the weight can influence the accuracy of weighing. Select an appropriate weight as listed below. A calibration weight (conforming to OIML, Class E2 or equivalent) is provided with the balance as a standard accessory.
