6. OPERATION

Initial Start-Up
Warm-up time of 15 minutes stabilizes the measured values after switching on.

1. Power ON/OFF

Power switch is located below the right side of the scale. Switch on the scale by pressing on/off. The display is switched on and the self test is started. If you want to switch off press again the key.

2. Zero

Environmental conditions can lead to the balance exactly zero in spite
of the pan not taking any strain. However, you can set the display of
your balance to zero any time by pressing key and therefore
ensure that the weighing starts at zero.

3. Tare

The weight of any container can be tared by pressing key, so that
with subsequent weighing the net weight of the object being weighed is always displayed.
Load weight on the pan.
Press key. Zero is displayed, and tare is subtracted.
Remove weight from the platform. Tared weight is displayed. It can set
only one tare value. It can display with a minus value.
Press key. Zero is displayed, tare weight is cleared.
