selected in the Configuration menu (see chapter 10.3.4 "Calibration functions").
Then proceed as follows:
• Switch to „WEIGHING“ with the Change key
• Press «
T » until „CALIBRATION“ is shown.
• Calibration is finished after a certain period of time
22.1.4 Automatic calibration
For automatic calibration with the built-in calibration weight „SET CALIBRATION MODE AUTO“ must be se-
lected in the Configuration menu (see chapter 10.3.4 "Calibration functions").
The balance now calibrates itself automatically every 24 hours and/or after each temperature change of 3
degrees Celsius, depending on the definition in the Configuration menu „SET CALIBRATION MODE AUTO“.
The time of the automatic calibration is as determined in the Configuration menu under „SET CALIBRATION
AUTOCAL. -TIME n h“. (e.g. 6 h for 06.00 o'clock in the morning)

NOTE
For automatic calibration by time and by time/temp. the date and time of the balance must first be cor-
rectly set (see chapter 10.3.7 "Date and time.").
Calibration can also be effected manually at any time when auto-calibration is activated.
Automatic calibration then takes place only if no weight has been placed on the pan for at least five min-
utes.
It is recommended that the time for auto-calibration be set outside the normal business hours (for exam-
ple, in the early morning).
