12.4 Performance characteristics
Response time Measured value update < 1 s per channel, depending on the type of sensor and connection
method
Reference operating
conditions • Calibration temperature: +25 °C ±5 K (77 °F ±9 °F)
• Supply voltage: 24 V DC
• 4-wire circuit for resistance adjustment
Maximum measured error The accuracy data are typical values and correspond to a standard deviation of ±3 s (normal
distribution), i.e. 99.8 % of all the measured values achieve the given values or better values.
