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 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
key (zeroing) active it should be checked if zero indicator
is displayed before
sample is placed on the pan. If not, press
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.
Do not overload the scale more than 20% of maximum capacity.
Do not press the pan with a hand.
For transportation pan, pan support and pan ring should be packed separately.
