(1) The accuracy values assume that the module was calibrated within the specified temperature range of 0…60 °C (32…140 °F).
(2) Module accuracy using 100 Ω or 200 Ω platinum RTDs with 0.5 excitation current depends on the following criteria:
(a) Module accuracy is ±0.6 °C after you apply power to the module or perform an autocalibration at 25 °C (77 °F) ambient with the module operating temperature at 25 °C
(77 °F).
(b) Module accuracy is ±(0.6 °C + DT x 0.034 °C/°C) after you apply power to the module or perform an autocalibration at 25 °C (77 °F) ambient with the module operating
temperature between 0…60 °C (32…140 °F). DT is the temperature difference between the actual operating temperature of the module at 25 °C (77 °F) and 0.034 °C/°C
is the temperature drift shown in the table for 100 Ω or 200 Ω platinum RTDs.
(c) Module accuracy is ±1.0 °C after you apply power to the module or perform an autocalibration at 60 °C (140 °F) ambient with the module operating temperature at 60
°C (140 °F).
