12.3.3 Internal calibration
For internal calibration with the built-in calibration weight “SET CALIBRATION MODE INTERNAL” must be
selected in the Configuration menu. (see chapter 6.3.5 "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
12.3.4 Automatic calibration
For automatic calibration with the built-in calibration weight “SET CALIBRATION MODE AUTO” must be
selected in the Configuration menu. (see chapter 6.3.5 "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
correctly set (see chapter 6.3.8 "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 minutes. It is recommended that the time for auto-calibration
be set outside the normal
business hours (for example, in the early morning).
12.4 Automatic Repeatability Test (ART)
During the Automatic Repeatability Test, the internal weight is measured 10 times, and the standard
deviation is calculated from this and logged.
