6-2 Smart Range Function

The AD-4212B-101 is equipped with two ranges. The precision range has a higher resolution. The

standard range has normal resolution.

The range switches automatically, depending on the value displayed. Pressing the RE-ZERO key

allows weighing in the precision range, regardless of the tare value.

The minimum weighing value can be fixed to 0.1 mg or 1 mg by pressing the SAMPLE key.

1 Press the RE-ZERO key.

The balance will start weighing, using the

precision range.

2 Place a container on the weighin g pan.

The weight value displayed exceeds the

precision range value and the balance will

switch to the standard range.

3 Press the RE-ZERO key.

The balance will switch to the precision range.

4 Place a sample in the container.

The weight value displayed is within the

precision range value and the balance will

perform a weighing, using the precision range.
