40.0 °C to 99.9 °C | 0.1 °C | ±0.30%rdg ± 1.0 °C | ±0.45%rdg ± 1.5 °C |
Accuracy = 0.3% x measured value ± 0.5 ºC
Analog Input | |||
Input voltage range | Temperature range display | Resolution | Accuracy |
0 to 2 V | -99.9 °C to 999.9 °C | 1 mV | ±1% TR ± 3 mV |
Accuracy = 1% x (TR – T0V) + 0.3% x (T1V - T0V)
T1V: The temperature measured under input voltage of 1 V.
T0V: The temperature measured under input voltage of 0 V.
TR: The current measured temperature.
