Scaling
Measurement accuracy for scaling: measurement accuracy for scaling (digits) = measurement
accuracy (digits) × scaling span (digits) / measurement span (digits) + 2 digits. Numbers below
the decimal point are rounded up.
±(((0.05/100) Ч 5000) + 2) Ч (2000/4000) + 2 = ±4.25
Measurement accuracy = ±5 digits = ±0.005 V
