For this we need to have an object which we know its exact weight. In this example we will use a
box with material that weighs 12.50 Kgr.
We will introduce the weight on the screen, using:
With the ZERO key we move through the different positions of the screen.
With the TARE key we increase or decrease from 0 to 9.
Once entered the value 12.50 will look like this: 001250
Press the FUNC key
We place the weight, in this case the box on the scale.
We press the FUNC key again to confirm.
We turn off, and we turn on, as in its normal operation.
The scale is already calibrated.
