Calibration is effected in the configuration menu. Depending on the balance model, this may be done exter-
nally, internally or automatically (see chapter 8.3.5 "Calibration functions" and see chapter 14.3 "Calibra-
tion").
With the aid of the “Intelligent Calibration Mode” the balance can itself determine the size of the calibration
weight, which enables an exact calibration with different size weights (in 10 g, 50 g, 100 g and 500 g steps,
depending on implementation).

Dual Range and Floating Range balances
With the Dual Range balances, weighing is always first carried out in the fine range, which is 10 times more
precise. When the fine range is exceeded the balance switches automatically into the coarse range.
The Floating Range balances have a fine range (10 times more precise), which moves over the entire weight
range. By pressing the tare key «
T
» the fine range can be called up as often as required over the entire weight
range.
7.9
Standardized balance
The standardized balances are provided with the EC/OIML certification or meet the local standardisation reg-
ulations.
The balance range and certain functions of the weighing output differ from the standard program in the case
of the standardized balances – in accordance with the EC/OIML provisions.
7.10 Switching on the balance
• Press «
ON/OFF
» to switch on the balance.
The balance carries out a diagnostic test in order to check the most important functions. After completion
of the start-up process (approximately ten seconds) “Zero” appears in the display.
The balance is ready for operation and is in the Weighing mode.
7.11 Auto-Standby Mode
The balance is equipped with an Auto-Standby mode, which can be activated or deactivated in the config-
uration menu.
If the Auto-Standby mode is activated, the balance automatically switches to Standby some time after the
last weighing or key operation (current-saving function).
The delay before switching to Standby is defined in the configuration menu (see chapter 8.3.6 "Weighing
mode").
• Press any button or put on a weight in order to switch the balance from the Standby mode back to the
Weighing mode again.
The balance must be calibrated on initial installation and after every relocation.
If you work in accordance with “Good Laboratory Practice GLP” observe the prescribed intervals between
calibrations (adjustments).
NOTE
If a circle appears in the main-display of a standardized balance, the indicated value is unstandardised.
In balances of class (1) the circle also stands for the warm-up phase.
Your Customer Service will be happy to assist you at any time if you have any questions on the stand-
ardization of the balance or on working with standardized balances.
