Internal Calibration (AutoCal
™)
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
AutoCal™ Internal Calibration
, and then touch
Calibration
.
The Balance begins to calibrate.
Alternately, touch the shortcut
Calibration
Icon from any Application home screen
to initiate an Internal Calibration.
Note:
For Non-Approved models, when AutoCal Internal Calibration is turned off, it changes to span calibration.
For Approved models, when AutoCal Internal Calibration is turned off, it is hidden.
The display shows the status, then returns to the current application.

5.3.3
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.
