Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 6:
7. The device of claim 1 wherein
the stimulus signal is a synchronous pulse signal that is synchronized with an output data rate of the electrostatic charge variation sensor,
the electrostatic charge variation sensor generates the second electrostatic charge variation measurement in a case where the first electrostatic charge variation measurement is less than a threshold value, and
the processor determines the electrostatic charge variation sensor passed the self-test in a case where the second electrostatic charge variation measurement is offset from the first electrostatic charge variation measurement, and determines the electrostatic charge variation sensor failed the self-test in a case where the second electrostatic charge variation measurement is not offset from the first electrostatic charge variation measurement.
