1 Getting to know B-S balances 1.1 Introducing the B-S line of balances Several types of construction – uniform operation AB-S (0.1 mg / 0.01 mg) • The B-S balance line ranges from high-resolution analytical balances (AB-S) with a readability of 0.1 mg / 0.01 mg through to precision balances (PB-S) with a readability of 0.001 g to 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.

2.3 Installing the draft shield Draft shield “0.
2.4 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.
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.
Adjusting (calibration) To obtain accurate weighing results, the balance must be adjusted to match the gravitational acceleration at its location. Adjusting is necessary • before the balance is used for the first time • at regular intervals during weighing service • after a change of location Procedure To obtain accurate results, the balance must be connected to the power supply for 30 minutes (AB-S analytical balances 60 minutes) in order to reach operating temperature before adjusting.

3.4 METTLER TOLEDO DeltaRange balances # 812.7 g 0.00 g METTLER TOLEDO DeltaRange balances have a movable fine range with 10 times smaller display increments over their entire weighing range. In this fine range an additional decimal place always appears in the display. The balance operates in the fine range • after switching on • after every taring operation If the fine range is exceeded, the balance display automatically switches to coarser display increments.

6.3 MT-SICS Interface commands and functions Many of the balances and scales used have to be capable of integration in a complex computer or data acquisition system. To enable you to integrate balances in your system in a simple manner and utilize their capabilities to the full, most balance functions are also available as appropriate commands via the data interface.
The MT-SICS commands listed below is a selected list of available commands. For additional commands and further information please refer to the Reference Manual “MT-SICS Basic-S balances 11780447” downloadable from the Internet under www.mt.com/AB-S. S – Send stable weight value Command S SI – Send value immediately Command SI ST – Send stable weight after pressing ± (transfer) key Command ST Inquiry of actual status of the ST function.
