CALIBRATION
8.1. Calibration Mode
The balance has the following modes.

Calibration using the internal mass (One-touch calibration, only for the FZ- i / FZ- i WP / FZ-GD 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 GLP / GMP compliant using the RS-232C serial interface, set “GLP output
(
info
)” of “Data output (
dout
)”. For details, refer to “10. FUNCTION TABLE”.

Calibration test is available only when “GLP output (
info
)” of “Data output (
dout
)” is set to “
1
” or “
2
”.

When calibrating, use the accessory breeze break. (All models of the FZ-
i
series, FZ-
i
WP series
and FZ-GD series, and the 120/200/300 of the FX- i series, FX- i WP series and FX-GD series
(including the 500 for the the FX-
i
series))
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:
