USER MANUAL 11____________________________________________________________________________________________________________________9. General operation principles1. After each location change user should level the balance and perform internal calibration.2. Weighed sample should be placed in the centre of the pan.3. Weighing result should be read when the indicator " " lights, which signalises stabilisation of a result.4. The balance allows tarring in the whole measuring range. To tare the balance pressT key (on the leftor on the right). Tarring does not extend measuring range, but only subtracts tare value from mass valueof a sample placed on the pan. To make the control of pan load easier and to avoid crossingmeasurement range, the balance has a load indicator calibrated 0÷100% Max.5. In direct sale use (d=e), make sure that0 zero indicator is displayed before sample is placed on thepan. If not, press0 key and wait until the balance is zeroed and zero indicator appears. In otherbalances the key does not operate.6. When the balance is not used but should be ready to work immediately, it can be switched off by pressingI/ key. The backlight of balance reading system is then switched off and the balance enters into"standby" mode, in which the balance maintains internal temperature and ability to start working withmaximum accuracy. Standby mode is signalled by the OFF indicator. To switch the balance on press I/key.7. The balance cannot be used to weigh ferromagnetic materials due to decrease of weighing accuracy.8. Balance mechanism is a precise device sensitive to mechanical shocks and strokes.Do not overload the balance more than 20% of maximum capacity.Do not press the pan with a hand.For transportation take off the pan (move it gently and lift it up) and pan support (lift it up)and protect from any damages.
