Accuracy

• DC voltage or current

Accuracy: Input accuracy + output accuracy

Inversely proportional to the span.

Input accuracy: (% of range)

-1000 – +1000 mV : ±0.01 %

-10 – +10 V : ±0.01 %

0 – 50 mA : ±0.02 % (Except the accuracy of input resistor.)

Output accuracy: ±0.04% of max. output range

[Example] Input Type -10 – +10 V, Input Range 1 – 5 V,

Output Type -5 – +5 V, Output Range 1 – 5 V

Input accuracy = Max. Input Range (20 V) ÷ Span (4 V) ×

0.01 % = 0.05 %

Output accuracy = Max. Output Range (10 V) ÷ Span (4 V)

× 0.04 % = 0.1 %

Accuracy= ±0.15 %

• Thermocouple

Overall accuracy: Input accuracy + output accuracy

Input accuracy: Accuracy + Cold Junction Compensation

Error 3°C (5.4°F)

Output accuracy: Max. Output Range ÷ Span × ±0.04%
