10. Operation principles
1. Weighed sample should be placed in the centre of the pan.
2. In direct sale use (d=e), make sure that zero indicator is displayed. If not, press 0 key
and wait until zero indication and zero indicator appears. In other balances the key does
not operate.
3. The balance is equipped with a tare equal to its range. To tare the balance press
→
T
←
key. Storing a tare value does not extend measuring range, but only subtracts it from a
load placed on a pan. To make weight control easier and to avoid range overdrawing, the
balance is equipped with a load indicator (graduated in percentages).
4. Weighing result should be read when the indicator "
" lights, which signalises
stabilisation of a result.
5. When the balance is not used but it is necessary to be ready to work immediately, it can
be switched off by pressing I/ key. The balance reading system is then switched off to
"standby" mode (signalled by the indicator "OFF"). To switch the balance on press I/
key. The balance is immediately ready to operate maximum accuracy (after self tests).
6. The mechanism of the balance is a precise device, sensitive to mechanical strokes and
shocks.
The balance should not be used to weigh ferromagnetic materials due to accuracy decrease.
Do not overload the balance more then 20% of maximum load (Max).
Do not press a pan with a hand.
Before transportation take off the pan (move it slightly and lift it up) and
the pan base and preserve from any damages.
