9. General operation principles
1. In order to confirm correctness of the scale during its operation, before starting and after finishing
every valid measurement series it is recommended to check weighing accuracy putting calibration
weight or other object of exactly known mass on the scale. In the case when allowable measurement
error of the scale is exceeded, it is recommended to perform calibration with external weight or
contact authorised service centre.
2. Weighed mass should be placed in the middle of the pan.
3. The scale allows taring in the whole measuring range. To tare the scale press
->T<- key. Taring does not extend measuring range, but only subtracts tare value from mass value of
a sample placed on the pan. To make the control of a load on the pan easier and to avoid exceeding
measurement range, the scales have load indicator calibrated 0÷100%.
4. Weighing result should be read when the indicator lights, which signalises result stabilisation.
5. When the scale is not used but it is necessary for it to be ready to work, it can be switched off by
pressing I/ key. The scale reading system is then switched off and scale goes to standby mode
signalled with OFF indicator. Switching the scale on is preformed by pressing I/ key.
6. In sales having →0← key (zeroing) active it should be checked if zero indicator →0← is displayed
before sample is placed on the pan. If not, press →0← key and wait until the scale is zeroed and
zero indicator appears. After that load can be placed on scale pan.
7. Scale mechanism is a precise device sensitive to overweight, mechanical shocks and strokes.
8. After every change of balance position, level the balance and perform internal calibration.
