The data contains the offset error, gain error, and linearity error in its respec-

tive basic setting. The data is related to nominal operation (preferred mount-

ing position, U

= 24 V) with pre-set 32-sample filter. Please also observe the

values for temperature drift and the tolerances under EMI.

All errors indicated as a percentage are related to the positive measuring

range final value.

The maximum tolerance values represent the worst case measurement in-

accuracy. They contain the theoretically maximum possible tolerances in the

corresponding measuring ranges. In the same way, the theoretical maximum

possible tolerances of the calibration and test equipment have been taken

into account. This data is valid for at least twelve months.
