• Before inserting the power adaptor, make sure that the operating voltage stated on the power adaptor agrees with the mains voltage. If not, please refer to Precisa Customer Service. • If the power adaptor or its cable is damaged, the balance must immediately be disconnected from the electricity supply (pull out the power adaptor).
Page 10
The balance may be operated after it has first been re-checked by a Precisa Service technician. • The operating instructions must be read by each operator of the balance and must be available at the workplace at all times.
2 Your balance ■ Your balance Construction and functions 2.1.1 Construction of the balance The balance consists of the balance body (1), the scale-pan holder (4) and the pan (5), which depending on the model may be square (fig. 2.1, right) or round (fig. 2.1, left). Depending on the model (see Chapter 2.3 “Data and parameters”) the balance additionally has a small (fig.

■ 2 Your balance The versatile weighing programs allow you to use the balances of the XT-Series not only for simple weighings but also in a simple manner for carrying out various weighing applications such as, for example, percentage- or component counting weighings and document the measurements obtained accurately and unequivocally.

■ 2 Your balance Application, conformity, labelling 2.2.1 Correct use of the balance The balance may only be used for the weighing of solid-materials and of liquids filled into secure containers and for animal weighing and density determinations. The maximum allowable load of the balance must never be exceeded, otherwise the balance may be damaged.
Balance labels Data and parameters The balances of Series XT are divided into five main-groups A, C, D, G and M. The letter in the name corresponds to the design specifica- tion (e.g. A = analytical balance, M = MilIigramme balance) the num- ber before it corresponding in each case to the maximum allowable load (in grammes).
• Calibration with built-in calibration weight (SCS) • Allowable ambient conditions – Temperature: 5°C … 40°C – Relative humidity: 25%... 85%, non-condensing If you have any questions on the technical data or require detailed technical information on your balance, please contact your Precisa Technical Representative.
(see Chapter 12 “Transport, storage and disposal”). • Read through these operating instructions, even if you already have experience with Precisa-balances, before you work with the balance and pay attention to the Safety recommendations (see Chapter 1 “Safety”).

NOTE A screwdriver is required for assembly. All parts must fit together easily. Do not apply force. Precisa Customer Service will be pleased to help you with any problems. Choice of a suitable location The balance location must be chosen in such a way as to guarantee perfect functioning of your balance, so that the allowable ambient conditions (see Chapter 2.3.1 “Technical data”) are maintained and,...
If the operating voltage is not the same as the mains voltage, the power adaptor must on no account be connected to the mains supply. Contact the Precisa-Customer Service. Levelling the balance To function properly, the balance must be precisely horizontal.
3 Starting up ■ NOTE In order to get exact measurements, the balance must again be ca- refully levelled after each relocation. Calibration of the balance Since the Earth's gravity is not the same everywhere, each balance must – in accordance with the underlying physical weighing principle –...
In balances of class (1) the circle also stands for the warm-up phase. Your Precisa Customer Service will be happy to assist you at any time if you have any questions on the standardization of the balan- ce or on working with standardized balances of the XT-Series.

14 Further information ■ 14.2.4 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 5.6 “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”.
■ 14 Further information 14.3.1 Density determination “Solid on bottom mode” A temperature-controlled reference-liquid (water) is poured into a bowl, placed on the scale pan and tared. The solid is then placed into the liquid and weighed. Subsequently, the solid is suspended so that it is still completely immersed in the water, but no longer touches the base.
