Indicating accuracy
Thermocouple input : Within ±0.3% of input range full scale ±1digit
however, for R or S input, the range 0 to 200°C (400°F), within ±6°C (12°F)
When B input, the range 0 to 300°C (600°F), accuracy is not guaranteed.
When K, J, T input, the range less than 0°C (32°F),
within ±0.5% of full scale ±1digit
(Cold junction compensating accuracy, ±1°C, at 0 to 50°C)
RTD input : Within ±0.3% of input range full scale ±1digit
Setting accuracy : The same as indicating accuracy
Input sampling period : 0.125 seconds
