Example of output error calculation
An analog output module is used for voltage output in a range of 0 to 10 V. The module is
operating at an ambient temperature of 30 °C, which means that the operational limit applies.
Technical specifications of the module:
● Operational limit for the voltage output: ±0.1 %
The result is an output error of approximately ±10 mV (±0.1 % of 10 V) across the rated
range of the module.
For example, the output value may range from 2.49 V to 2.51 V at an actual voltage of
2.50 V.
Note
Bipolar measuring ranges
The calculation also applies to bipolar measuring ranges.
mV is also returned at an input range of ±10 V and a linearity error of ±0.1%.
