The total deviation of the measuring system is hence 0.46 %.
Deviation in mm: 0.46 % of 12000 mm = 55 mm
The example shows that the measurement error in practice can be considerably higher than the
basic accuracy. Reasons are temperature influence and Turn down.
The thermal change of the current output is in this example is nearly small.
