The above accuracy values do not include the thermocouple accuracy.
±0.1°C/°C is added (for all thermocouples) with the operating ambient temperature of this product at 0°C to 18°C and 28°C to 50°C.
accuracy is not specified. In the temperature range to be measured at -200°C or lower,
The reference thermo electric force is calculated by the "broken line approximation" according to JIS C 1602-1995.
If this product and the thermocouple are connected via a plug, an error for contact temperature compensation is added.
