6.10.3 Internal calibration
(only ARJ/PRJ models)
For an internal calibration with the built-in calibration weight, “SET CALIBRATION MODE
INTERNAL” must be selected in the configuration menu (see Chapter 8.6 “Calibration
functions”).
Then proceed as follows:
• Switch to “WEIGHING” using the “ ” key
• Press “CAL” until “CALIBRATION” appears.
• The calibration is finished after a certain period of time.
6.10.4 Automatic calibration
(onl
y ARJ/PRJ models)
For automatic calibration with the built-in calibration weight, “SET CALIBRATION MODE
AUTO” must be selected in the configuration menu (see Chapter 8.6 “Calibration
functions”).
The balance now calibrates itself automatically every 24 hours and/or after each
temperature change of 3 degrees Celsius, depending on how “SET CALIBRATION
AUTOCAL” has been defined in the configuration menu.
The timing 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 set correctly (see Chapter 8.9 “Date and time”).
The calibration can also be initiated manually at any time, even when auto-calibration is
activated.
The automatic calibration then takes place only if no weight is placed on the pan for at
least five minutes.
It is recommended that the time for the auto-calibration be set at a time outside the normal
business hours (for example, in the early morning).
