PERFORMANCE in percentage of span

Overall accuracy: Input accuracy + output accuracy
See CALCULATION EXAMPLES OF OVERALL ACURACY
• Input accuracy*: (% of max. input range)
-1000 – +1000 mV : ±0.05 %
-10 – +10 V : ±0.05 %
0 – 50 mA : ±0.1 %
• Output accuracy**: ±0.04% of max. output range

*Inversely proportional to the span.
For math functions, the input accuracy equals that of either input 1 or 2, whichever is greater, with the following parameter setting:
K1=K2=1, A2=0%, X2=100% for temp./press. compensation
K0=0.5, K1=K2=1, A0=A1=A2=0% for four arithmetic functions
For selector functions, it equals that of the selected signal.
**Inversely proportional to the span.
Temp. coefficient: ±0.01 %/°C (±0.006 %/°F) of max. span
Response time: ≤ 0.5 sec. (0 – 90 %)
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] Function: Temperature compensation w/o square root extraction; K1=K2=1, A2=0%, X2=100%
Input 1: Type -10 – +10 V / range 1 – 5 V
Input 2: Type 0 – 50 mA / range 4 – 20 mA
Output: Type 0 – 20 mA / range 4 – 20 mA
Input 1 = Max. Input Range (20 V) ÷ Span (4 V) × 0.05% = 0.25%
Input 2 = Max. Input Range (50 mA) ÷ Span (16 mA) × 0.1% = 0.31%
Output = Max. Output Range (20 mA) ÷ Span (16 mA) × 0.04% = 0.05%
Accuracy = 0.31% (input 2 > input 1) + 0.05% = 0.36%
