The analogue outputs are calibrated to ensure that outputs are correctly scaled:

for example, when the output is scaled to 4...20 mA, the low end of the scale

is 4 mA and high end 20 mA exactly. However, when 0... 20 mA output is

used, the output cannot be adjusted to exactly 0 mA, but to 50 µA. When 0...1

V, 0...5 V or 0...10 V output is in use, the output is adjusted to 50 mV. The

following table summarizes the correct output values.

Summary of the correct output values:

Output scale:

0...20 mA 4...20 mA 0...1 V 0...5 V 0...10 V

low end: 50 µA 4 mA 50 mV 50 mV 50 mV

high end: 20 mA 20 mA 1 V 5 V 10 V
