11.2 Multi-Interval
The single-range scale can be set as a multi-interval scale with two or three
different weighing ranges, or intervals.
Example of a three-interval scale with:
lowest weighing range: 0 kg to 1500 kg / 0.5 kg
Middle weighing range: 1500 kg to 3000 kg / 1.0 kg
Highest weighing range: 3000 kg to 6000 kg / 2.0 kg
The weighing range, or interval, is automatically switched dependent on the
applied load both when loading and when removing the load.

After tare balancing, the net weight of the scale is displayed with the scale in­
terval of the lowest weighing range, so that light weights are weighed with the
greatest possible accuracy even when there is already a load on the scale. The
maximum tare input value is the maximum load of the lowest weighing range.
When configuring the multi-interval scale, the maximum load and interval can
be freely selected for each range; only the number of decimal places has to be
the same for all ranges. If 0.5 kg and 1 kg scale intervals are used, for exam­
ple, 0.5 and 1.0 must be entered as the intervals. Additionally, the maximum
resolution of the load cells being used (e.g. 3000d) must not be exceeded in
any of the set ranges.
