The digital accuracy is the accuracy after A/D conversion including linearisation and conversion.
The 4 to 20 mA output, an additional error amounting to
<
0.1 % of the measuring span is caused by
D/A conversion (D/A error).
The total error under reference conditions at the analog output is the sum of the digital error + D/A
error + the cold junction error, wherever applicable.
