7. CALIBRATION

7-1 Calibration Mode

The FZ-i WP series and the FX-i WP series balance has the following two modes.

Calibration using the internal mass (One-touch calibration, only for the FZ-i WP series)
Calibration using an external weight
Calibration test using an external weight (Calibration test does not perform calibration.)

Terms

The following terms are defined as follows:
External weight

= A weight that you have. Referred to as a calibration weight when used for calibration.

Calibration weight = A weight used for calibration
Target weight

= An external weight used for calibration test

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 environment has changed.

Do not allow vibration or drafts to affect the balance during calibration.
To output the data for GLP using the RS-232C serial interface, set “GLP output ( info )” of “Data

output ( dout )”. For details, refer to “9. FUNCTION TABLE”.

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

Caution on using an external weight

The accuracy of an external weight will influence the accuracy of weighing. Select an appropriate

weight as listed below:
