9 Basic Operation

After new purchase of the balance or after a long storage, you have to calibrate the balance before the first
commissioning. Level the balance with the adjustable feet horizontal until the air bubble in the level is in
the center of the Level Indicator. Give the balance after changing the location a warm-up time min. 1 hour
before using. This time is necessary for the balance to adapt to the eventual temperature.

9.1 [Power On/OFF]

Press the [On/OFF] button to turn on the balance. The display shows the message "ON". Then the max.
weighing range is displayed. The balance will carry out a self-test (F----1 to F----9). When the "0.0000 g" in
display appears, the balance is ready for operation.
Press the [On/OFF] button and keep it pressed, until the display shows the message "OFF". The balance
will switch off then.

9.2 TARE

When the pan is empty and indication is different than zero press [TARE] key.
Weighing with tare: Place the weighing box and press the [TARE] button. After standstill control the zero
display appears. The weight of the container is now internally saved. Weigh the material, the net weight
will be indicated. The weight of the weighing container will be displayed as a minus number after removing
the weighing container. The tare weight is saved until it is deleted. Remove the load from the balance and
press the [TARE] button. The tare procedure can be repeated as many times as necessary, for example
with initial weighing of several components for a mix (add-on weighing). The limit is reached when the
total weighing range capacity is full.
