2 1 Getting to know the B balance line 1.1 AB Introducing the B balance line Several types of construction – uniform operation The B balance line ranges from high-resolution analytical balances (AB balances) with a readability of 0.1 mg via precision balances (PB balances) up to industrial balances (SB balances) with a readability from 0.1 g to 1 g. The weighing ranges extend from 51 g to 32 kg. The operation of all these balances is identical.

4 1.3 The keys of the B balances (overview) B balances have two operator control levels: the weighing mode and the menu. The keys have different meanings, depending on the operator control level and how long a key is pressed. Weighing mode (operation) Press and hold Press briefly • Switch on On → 0/T← Off • Switch off • Tare • Switch F • Change settings • Call function A function must be activated in the menu, otherwise "F nonE" appears in the display.
2 Startup 2.1 Unpacking / standard equipment All B balances are supplied in an environmentally harmless package.
6 2.3 Setting up The optimum location The correct location makes an important contribution to the accuracy of the weighing results of high-resolution analytical and precision balances. Hence, ensure a • stable, vibration-free position as horizontal as possible. Avoid • direct sunlight, • excessive temperature fluctuations, • drafts. The best position is on a stable bench in a corner protected against drafts as far as possible from doors, windows, radiators or the ventilation slots of air conditioners.
1 2 3 Leveling B balances have a level control and adjustable leveling feet to compensate for slight irregularities in the weighing bench surface. The balance is exactly horizontal when the air bubble 1 is in the middle. Procedure Turn the two leveling feet 2 and 3 as shown in the diagram or described in the table so that air bubble 1 is in the middle.
8 2.4 Adjusting (calibration) To obtain accurate weighing results, the balance must be matched to the acceleration due to gravity at its location. Cal/Menu CAL Adjusting is necessary • before the balance is used for the first time, ------ • at regular intervals during weighing operations, • after a change in location. 2000.00 Procedure ------ To obtain accurate results, before adjusting the balance must be switched on for 20–30 minutes so that the operating temperature will be reached.

If the container is removed from the balance, the tare weight will be shown as a negative value. The tare weight remains stored until -12+01 g → 0/T← is again pressed or the balance is switched off.
4 4.1 Menu Overview You can use the menu to activate functions (F) and change the balance settings. With certified balances/scales, the unit selection can be blocked following installation if required by national legislation. A detailed description of the menu options is given in sections 4.2. Entry into menu Press and hold Cal/Menu until "MENU" appears in the display. Release key, the 1st menu option "rESEt" appears. Select menu options Press briefly.

The more unstable the weighing sample, the longer the selected weighing time. Requirement "F dYn A" for automatic start or "F dYn M" for manual start must be activated in the menu (section 4). Factory setting is a weighing time of 3 seconds (t = 3"). Tare container → 0/T← ➞ Tare: key. 0.00 g 0.00 gk 257.
