output

Absolute accuracy in °C: 0.25°C (see the above table)

CJC error (3°C) added: 3.25°C

➠ Input accuracy = 3.25°C ÷ 1000°C × 100 = 0.325 %

Output span: 16 mA (20 – 4)

➠ Output accuracy = 20 mA ÷ 16 mA × 0.04 = 0.05 %

➠ Overall accuracy including CJC error = 0.325 + 0.05 =

±0.38 % of span

• RTD

Accuracy: Input accuracy + output accuracy

Inversely proportional to the span.

Input accuracy: (whichever is greater)

±0.1 % of input range or ±0.15°C (Pt and JPt)

±1°C (Cu 10)

Output accuracy: ±0.04% of max. output range

[Example] Pt 100, 0 – 100°C, Output Type -5 – +5V, Output

Range 1 – 5V

Input Accuracy* (0.15°C**) ÷ Span (100°C) × 100 %

+ Max. Output Range (10V) ÷ Span (4V) × 0.04 %

= ±0.25 %

* Calculate the accuracy in °C.

** 100°C × 0.1 % = 0.1°C ≤ 0.15°C. 0.15°C is used as input

accuracy value.

• Potentiometer

Accuracy: Input accuracy + output accuracy

Inversely proportional to the span.

Input accuracy: (% of range)

0 – 100 Ω : ±0.05 %

0 – 300 Ω : ±0.05 %

0 – 600 Ω : ±0.03 %

0 – 1200 Ω : ±0.03 %

0 – 2500 Ω : ±0.01 %

0 – 5000 Ω : ±0.01 %

Output accuracy: ±0.04% of max. output range

[Example] Total Resistance 0 – 1200 Ω, Input Range 250–

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

Max. Input Range (1200 Ω) ÷ Span (500 Ω) × 0.03 %

+ Max. Output Range (10 V) ÷ Span (4 V) × 0.04 %

= ±0.18 %
