12.4 Performance characteristics
12.4.1 Response time
The measured value update depends on the type of sensor and connection method and moves
within the following ranges:
Resistance thermometer (RTD) 1 s
12.4.2 Reference operating conditions
Calibration temperature: +25 °C ±5 K (77 °F ±9 °F)
12.4.3 Maximum measured error
The accuracy data are typical values and correspond to a standard deviation of ±3 s
(normal tribution), i.e. 99.8% of all the measured values achieve the given values or
better values.
