10 OPERATION MANUAL__________________________________________________________________________________________________________________9. General rules1. It is advised to check scale indication accuracy before and after series ofmeasurement using any load with known weight. To check the scale with legalverification uses a calibration weight with valid calibration certificate. In casepermissible error is exceeded it is advised to contact the nearest service tocalibrate the scale.2. Weighed sample should be placed in the centre of the pan.3. The scale is equipped with a tare equal to its range. To tare the scale press→T← key (left or right). Storing a tare value does not extend measuring range,but only subtracts it from a load placed on a pan. To make weight controleasier and to avoid range overdrawing, the scale is equipped with a loadindicator (graduated in percentages).4. Weighing result should be read when the indicator " " lights, whichsignalizes stabilization of a result.5. When the scale is not used but it is necessary to be ready to workimmediately, it can be switched off by pressing I/ key. The scale readingsystem is then switched off to "standby" mode. To switch the scale on pressI/ key. The scale is immediately ready to operate maximum accuracy (afterself tests).6. Before each measurement make sure that zero indicator is displayed. If zeroindicator does not displayed or “----“ communicate appears, press →0← keyand wait until zero indication and zero indicator appears7. The mechanism of scale is a precision devices and susceptible on congestions,impacts and mechanical shakes.Do not overload the scale more then 20% of maximum load (Max).Do not press a pan by hand.Scale should be protected during the transport.
