7. CALIBRATION
7-1 Calibration Mode
Calibration / Calibration test
(Calibration test does not perform calibration.)
Calibration Using the Internal mass (One-touch calibration, only for the FZ-CT series)
Calibration using an external weight
Calibration test using the internal mass (Only for the FZ-CT series.)
Calibration test using an external weight
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
= A weight used for calibration test
Caution
When calibrating, be sure to install the provided large breeze break.
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 report 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:
Model Usable calibration weight Adjustable range
FZ-1200CT / FX-1200CT 250 g, 200 g , 100 g, 50 g, 20 g
FZ-700CT/ FX-700CT 150 g, 100 g , 50 g, 20 g
FZ-500CT/ FX-500CT 100 g , 50 g, 20 g
-0.0150 g to +0.0150 g
The calibration weight in bold type: factory setting
The calibration weight value can be adjusted within the range above.
Display
This indicator means “the balance is measuring calibration data”.
Do not allow vibration or drafts to affect the balance while this
indicator is displayed.
