  • Page 17: Temperature Correction Function

    ___________________________________________________________________ 1.2 Temperature Correction Function The temperature sensor used in the 3540's temperature probe is a thin platinum film whose resistance changes according to temperature. The resistance of the film is detected and converted to a temperature value by the CPU. This section explains use of the 3540's temperature coefficient correction function.
  • Page 18 ___________________________________________________________________ For 3540 temperature correction, conductivity σ is calculated as 1. Accordingly, when the resistance value R that is displayed at , the measured the time of temperature correction is taken as R resistance at the current ambient temperature is expressed by the following expression.

  • Page 19: Effects Of Thermoelectromotive Force

    ___________________________________________________________________ 1.3 Effects of Thermoelectromotive Force Thermoelectromotive force is the potential difference at the junction of two dissimilar metals. If this emf is large, measurement errors can result. As the 3540 uses constant direct current flowing through the object being measured, readings can be affected by even slight thermoelectromotive force.
  • Page 20 ___________________________________________________________________ If the measurement error is large due to the effect of thermoelectromotive force, the following countermeasures can be employed. (1) Reverse the probes and use the average measured value. (2) As the thermoelectromotive force is temperature dependent, maintain a constant temperature in the measurement environment. ___________________________________________________________________ 1.3 Effects of Thermoelectromotive Force...
