PERFORMANCE in percentage of span
Overall accuracy: Input accuracy + output accuracy
Inversely proportional to the span.
See CALCULATION EXAMPLES OF OVERALL ACURACY.

Burnout response: ≤ 10 sec.
Line voltage effect: ±0.1 % over voltage range
Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength: 2000 V AC @1 minute  (input to output to power to ground)

CALCULATION EXAMPLES OF OVERALL ACCURACY
[Example] Pt 100, 0 – 100°C, Output Type -5 – +5 V, Output Range 1 – 5 V
  Input Accuracy*¹ (0.15°C*²) ÷ Span (100°C) × 100 % + 
  Max. Output Range (10 V) ÷ Span (4 V) × 0.04 % = 0.25 %
*1. Calculate the accuracy in °C.
*2. 100°C × 0.1 % = 0.1°C ≤ 0.15°C. 0.15°C is used as input accuracy value.
