CALCULATION EXAMPLES OF OVERALL ACCURACY
[Example 1]
Input: Pt 100 (JIS ’97, IEC), 0 – 500°C
Output: 4 – 20 mA DC
1) ±0.15°C referred from Table 1, is converted into % by the following equation: 0.15°C ÷ 500°C = 0.03%.
2) 0.03% ≤ 0.1% of span. ➠ 0.1% is selected.
3) Output span 16 mA (= 20 mA – 4 mA)
Max. span 20 mA
Output span ≥ 1/10 of max. span ➠ No need of adding 0.2%.
4) Overall accuracy equals ±0.1% of span
[Example 2]
Input: Pt 100 (JIS ’97, IEC), 0 – 100°C
Output: 2.0 – 2.5 V DC
1) ±0.15°C referred from Table 1, is converted into % by
the following equation: 0.15°C ÷ 100°C = 0.15%.
2) 0.15% ≥ 0.1% of span. ➠ 0.15% is selected.
3) Output span 0.5 V (= 2.5 V – 2.0 V)
Max. span 5 V
Output span ≤ 1/10 of max. span ➠ Add 0.2%.
