1 Specifications without using the reference junction compensation feature (0.00°C in manual input mode), under standard
operating conditions, but at an ambient temperature of 23°C±1°C.
2 Specifications without using the reference junction compensation feature (0.00°C in manual input mode), under standard
operating conditions. If the ambient temperature is between 5°C to 18°C or 28°C to 40°C, add the temperature coefficient
compensation to the accuracy.
3 If the reference junction compensation feature is used, when the input terminal temperature is balanced, add the reference
junction compensation error to the accuracy for every ±0.3°C of reference junction temperature measurement error.
• The 2553A’s internal reference junction temperature measurement accuracy is ±0.3°C.
• The external reference junction temperature measurement accuracy when the RJ sensor 257875 (sold separately) is used
with the 2553A is ±0.3°C (typical value).
4 Specifications under standard operating conditions but at an ambient temperature of 23°C±1°C.
5 Specifications under standard operating conditions. If the ambient temperature is between 5°C to 18°C or 28°C to 40°C, add
the temperature coefficient compensation to the accuracy.
• Does not include the thermocouple error.
• The stability and accuracy for the temperatures between the set temperatures are those obtained by linear interpolation.
• To add the temperature coefficient compensation or the reference junction compensation error to the accuracy figure for a
temperature between the set temperatures, linearly interpolate the accuracies obtained after adding the compensation.
• The thermoelectromotive force for temperatures not listed in the table will be ±(60ppm of V
T
+ 4 µV) with respect to standard
thermoelectromotive force V
T
of the interpolating polynomial of IEC 60584-1.
• On models with the -UF suffix code, °F display is possible. Convert the source range, set temperature, stability, accuracy,
temperature coefficient, and reference junction compensation error using the following expression. The resolution is 0.1°F.
