13.4 Performance characteristics
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
Thermocouples (TC) 1 s
Reference temperature 0.9 s
Reference operating
conditions
When recording step responses, it must be taken into account that the times the
internal reference measuring point are added to the specified times where applicable.
• Calibration temperature: +25 °C ±3 K (77 °F ±5.4 °F)
• Supply voltage: 24 V DC
• 4-wire circuit for resistance adjustment
Maximum measured error In accordance with DIN EN 60770 and the reference conditions specified above. The
measured error data correspond to ±2 σ (Gaussian distribution). The data include non-
linearities and repeatability.
