16.1.3 Internal calibration
For an internal calibration with the built-in calibration weight “SET CALIBRATION MODE INTERNAL” must
be selected in the configuration menu (see Chapter 9.5 “Calibration functions”).
Then proceed as follows:
• Switch to “BALANCING” with the «
MODE
»-key
• Press
«0/T»
until “CALIBRATION” is shown.
• The calibration is finished after a certain period of time.
16.1.4 Automatic calibration
For an automatic calibration with the built-in calibration weight “SET CALIBRATION MODE AUTO” must be
selected in the configuration menu (see Chapter 9.5 “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 AUTOCAL”.The
time of the automatic calibration is as determined in the configuration menu under “SET CALIBRATION AU-
TOCAL. -TIME n h” (e.g. 6 h for 06.00 o'clock in the morning).
16.2 Software update
Our balances are instruments which are being continuously advanced and improved. For this reason, it is
possible to update to the latest version of the instrument software via the internet.
In order to update your software, you need to download the Download Tool from the website and install it
onto a PC with Windows.
The software for the balance can also be downloaded from the Downloads area on the website. This can
then be loaded into the instrument with the aid of the download tool.
16.3 Cleaning
The balance must be treated carefully and cleaned regularly. It is a precision instrument.

NOTE
For the automatic calibration by time and by time/temp. the date and time of the balance must first be cor-
rectly set (see Chapter 9.8 “Date and time”).
The calibration can also be effected manually any time while 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).
DANGER
For maintenance work, the balance must be separated from the power supply (remove power adaptor
plug from socket). Also ensure that the balance cannot be reconnected to the power supply during the
work by a third party.
Take care during cleaning that no liquid penetrates into the balance. If liquid is spilt on the balance, the
latter must immediately be disconnected from the electricity supply and must only be used again after it
has first been checked by a Service Engineer.
The connections of the balance ans the power adaptor must not come into contact with liquids.
