PERFORMANCE
Accuracy: Input accuracy + output accuracy
Inversely proportional to the span.
Input accuracy: ±0.03 % of the selected freq. range
(The input span 100 kHz is used for calculation with 0 – 200 kHz range. The input accuracy is fixed at ±0.03 % when [Frequency range ÷ Input span] equals 1 or less.)
Output accuracy: ±0.03 % of the selected output range
See CALCULATION EXAMPLES OF OVERALL ACCURACY.
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) of I/O range at -5 to +55°C [23 to 131°F]
Response time: 0.5 sec. + 1 pulse cycle (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] Open collector input, 0 – 50 kHz; 1 – 5 V output.
Selected freq. range (100 kHz) ÷ Input span (50 kHz)× Accuracy (0.03 %)= 0.06 % (Input accuracy)
Selected output range (20 V) ÷ Output span (4 V) × Accuracy (0.03 %)= 0.15 % (Output accuracy)
Overall accuracy = 0.06 + 0.15 = ±0.21 %
