The indicated value is defined as the difference between an indication in loaded condition
and an indication in unloaded condition. The indication at the beginning of each
measurement series should be zeroed, or taken into account by computation during the
evaluation following the measurement.
NOTE: Recording of non-zeroed values provides additional information about the
zero signal behaviour.
For torque measuring devices with defined scale (indication in the unit of torque), the
indication should be zeroed at the beginning of each measurement series.
