Measuring accuracy in case of linear scaling
Accuracy during scaling (digits) = measuring accuracy (digits) × multiplier + 2 digits (rounded up)
where the multiplier = scaling span (digits)/measuring span (digits).
Example: Assuming that
• range type: 1-5 V
• measuring span: 1.000 to 5.000 V
• scaling span: 0.000 to 2.000 Then,
Measuring accuracy = ±(0.1% × 5 V + 2 digits)
= ±(0.005 V [5 digits] + 2 digits)
= ±7 digits
Multiplier = {2000 digits (0.000 to 2.000)}/4000 digits (1.000 to 5.000) = 0.5
Accuracy during scaling = ±(7 × 0.5 + 2) digits = 6 digits (rounded up)
