See HOW TO CALCULATE THE ACCURACY.

  • Input accuracy: (% of input range) 0 – 50 Ω : ±0.02 % 0 – 8 kΩ : ±0.02 %
  • Output accuracy: (% of output range) Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) of I/O range at 0 to 55°C [32 to 131°F] Response time: ≤ 0.9 sec. (0 – 90 %) Line voltage effect: ±0.1 % over voltage range Insulation resistance: ≥ 100 MΩ with 500 V DC Dielectric strength:

1500 V AC @1 minute (input to output 1 or output 2 or

power to ground)

500 V AC @1 minute (output 1 to output 2 to power)

HOW TO CALCULATE THE ACCURACY ■ Overall Accuracy [Example] Total resistance 800 Ω, 250 – 750 Ω input, 1 – 5 V output Input Accuracy = Max. Range ÷ Input Span × Input Accuracy = 800 ÷ 500 × 0.01 = 0.02 Output Accuracy = Max. Range ÷ Output Span × Output Accuracy Overall Accuracy = 0.02 + 0.1 = ±0.12 %
