    摘要: We disclose herein a method for testing a batch of environmental sensors to determine the fitness for purpose of the batch of environmental sensors, the method comprising: performing a plurality of electrical test sequences to the sensor inputs of the batch of environmental sensors to measure electrical responses of the sensor outputs of the batch of environmental sensors; correlating the measured electrical responses from the batch of environmental sensors to predetermined environmental parametric ranges of at least one environmental sensor so as to define correlated electrical test limits; and determining the fitness for purpose of the batch of environmental sensors if the measured electrical responses are within the correlated electrical test limits.

    摘要: We disclose herein a method for testing and/or calibrating a thermopile based device. The method comprising: applying an electrical bias of a first polarity to the thermopile based device and measuring a first value of an electrical parameter; and applying an electrical bias of a second polarity to the thermopile based device and measuring a second value of an electrical parameter.
