Internal Calibration
Calibration is accomplished with the internal calibration mass. Internal Calibration can be performed at
any time, provided the balance has warmed up to operating temperature and is level.
With the Balance turned ON and no load on the pan, touch Internal Calibration. Alternatively, press the
Cal key on the balance.
The Balance begins to calibrate. And no load on the pan, touch Internal Calibration.
The display shows the status, then returns to the current application.
To cancel at any time, press Save.
5.2.3
Automatic Calibration
When Automatic Calibration is set ON, the balance performs a self-calibration:
• when it senses a temperature change of 1.5°C
•
or every 11 hours
AutoCal will automatically calibrate the Balance (using the internal mass) each time there is a change in
temperature significant enough to affect accuracy or every 11 hours.
An information screen will appear when an Automatic Calibration is about to start. Three option buttons
will be displayed:
Now
– Press to perform the calibration directly.
5 min – Press to perform the calibration after 5 minutes.
Deactivate – Press to deactivate the Automatic Calibration function.
