1 Getting to know B-S balances 1.1 AB-S (0.1 mg) Introducing the B-S line of balances Several types of construction – uniform operation • The B-S balance line ranges from high-resolution analytical balances (AB-S) with a readability of 0.1 mg through to precision balances (PB-S) with a readability of 0.001 g to 0.1 g. The weighing ranges extend from 51 g to 8.1 kg. • The operation of all theses balances is identical.

1.3 Overview of key functions The balances have two operator control levels: the weighing mode and the menu. The function of each individual key depends on the operator control level and how long the key is pressed. Weighing mode Key functions in weighing mode 0.
2 Startup 2.1 Unpacking / standard equipment All B-S balances are supplied in environmentally compatible packaging.
2.3 Setting up, leveling, preparations for weighing below the balance, connecting to power supply 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.
Leveling B-S balances have a spirit level and two adjustable leveling feet to compensate for slight irregularities in the surface of the weighing bench. The balance is exactly horizontal when the air bubble is in the middle of the level glass.
2.4 Cal/Menu Adjusting (calibration) To obtain accurate weighing results, the balance must be adjusted to match the gravitational acceleration at its location. CAL à Adjusting is necessary • before the balance is used for the first time • at regular intervals during weighing service • after a change of location.

4 4.1 Menu Overview and operation In the menu you can change weighing units (only possible with certified balances if permitted by national weights and measures legislation) and, if the balance is fitted with the optional RS232C interface, carry out the settings for this interface. A description of the individual menu options is given in section 4.2.
Using the menu Opening the menu Cal/Menu 0.01 g In weighing mode, press and hold down the «Cal/Menu» key until “MENU” appears in the display. Release the key: the 1st menu option is displayed. Notes: The menu option “Reset” is only displayed if the balance is equipped with the optional RS232C interface, otherwise “Unit 1” appears as first menu option.
4.2 Description of menu options 4.2.1 Reset or recording of balance settings (1st menu option “RESET”) Note: This menu option is only available if the balance is equipped with the optional RS232C interface! Reset balance settings Cal/Menu rESEt ➞ Select “Reset”, press and hold down the «Cal/Menu» key until the message “r donE” confirms that all menu settings have been reset. The balance then reverts to weighing mode and works with the following factory settings: r donE 0.
4.2.2 Weighing unit 1 (2nd menu option “UNIT 1”) Depending on requirements, the balance can operate with the following units: “ Unit 1 g Unit 1 kg “ “ Unit 1 cl Unit 1 g Unit g kg mg ct lb oz ozt GN dwt mo m H tl S tl t tl cl Conversion factor gram kilogram milligram carat pound ounce troy ounce grain pennyweight momme Mesghal Hong Kong taels Singapore taels Taiwan taels tical 1 kg 1 mg 1 ct 1 lb 1 oz 1 ozt 1 GN 1 dwt 1 mo 1m 1 H tl 1 S tl 1 t tl 1 cl = = = ≈ ≈ ≈ ≈ ≈ ≈ ≈ ≈ ≈ ≈ ≈ 1000 g 0.

At this menu option you can select the peripheral device connected to the optional RS232C interface (factory setting: a printer is connected). The balance automatically saves the appropriate settings (4.2.5– 4.2.9) for every peripheral device. Printer Connected to a printer (factory setting: bd 2400, 7b–E, HS oFF).
“ bd 2400 bd 4800 “ “ Baud rate (7th menu option) Note: This menu option is only available if the balance is equipped with the optional interface and you have selected the setting “Printer” or “Host” at the 4th menu option (Peripheral unit)! The baud rate (data transfer rate) determines the speed of transmission via the serial interface. The unit is the baud (bd) = 1 bit/second. The following settings are available: 600 bd, 1200 bd, 2400 bd, 4800 bd, 9600 bd and 19200 bd. bd 19200 “ 4.2.
