CALCULATION EXAMPLES OF OVERALL ACCURACY

• DC Voltage

1) 0 – 200 mV

Absolute value accuracy (Table 1): 40 μV

40 μV ÷ 200000 μV × 100 = 0.02 % < 0.1 %

➠ Overall accuracy = ±0.1% of span

2) 0 – 4 mV

Absolute value accuracy (Table 1): 10 μV

10 μV ÷ 4000 μV × 100 = 0.25 % > 0.1%

➠ Overall accuracy = ±0.25 % of span

• Thermocouple

1) K thermocouple, -150 – +1370°C

Absolute value accuracy (Table 1): 0.25°C

CJC error (1.0°C) added: 1.25°C

1.25°C ÷ 1520°C × 100 = 0.082 % < 0.1 %

➠ Overall accuracy including CJC error = ±0.1 % of span

2) K thermocouple, 50 – 150°C

Absolute value accuracy (Table 1): 0.25°C

CJC error (1.0°C) added: 1.25°C

1.25°C ÷ (150 – 50)°C × 100 = 1.25 % > 0.1 %

➠ Overall accuracy including CJC error = ±1.25 % of span

• RTD

1) Pt 100, -200 – 800°C

Absolute value accuracy (Table 1): 0.15°C

0.15°C ÷ (800 – -200)°C × 100 = 0.015 % < 0.1 %

➠ Overall accuracy = ±0.1 % of span

2) Pt 100, 0 – 100°C

Absolute value accuracy (Table 1): 0.15°C

0.15°C ÷ 100°C × 100 = 0.15 % > 0.1 %

➠ Overall accuracy = ±0.15 % of span
