How often do monitors need to be calibrated?
The TempTale product design uses a self-calibrating circuit. This means that every time a monitor is started, the microprocessor determines the circuit resistance by using a high-precision resistor in place of the thermistor. This allows the unit to compensate for any effects the electronic circuit has on accurate temperature readings over the life of the product. A properly assembled unit will hold an accuracy of between +/- 0.5°C and +/- 1°C depending on the temperature range in which it is used. Therefore, a TempTale monitor does not need to be “recalibrated” over its useful lifetime.
