7. TIPS


Warming up is necessary before any operation is made to the balance

In TARE mode, the value of the taring object cannot exceed the rated maximum capacity
of the balance

Calibration is necessary to ensure a reliable weighting

Switch off the balance when it is not used

It is suggested to turn the round pan clockwise before taking it off the balance

Never use scourers or substances that can grate to clean metallic parts such as stainless
steel, aluminum, coatings, etc. as they damage the balance and produce an early ageing of
the equipment. Use a fluff-free cloth dampened with soaped water that does not contain
abrasives
