1. A method of verifying the operation of an accelerometer, said method comprising:
- channeling a high frequency signal through a positive lead of the accelerometer; and
detecting a signal at a negative lead of the accelerometer, wherein, if the detected signal is substantially similar to the high frequency signal channeled through the positive lead, the integrity of the accelerometer is verified.

Abstract
A method of verifying the operation of an accelerometer is provided. The method includes channeling a high frequency signal through a positive lead of the accelerometer, and detecting a signal at a negative lead of the accelerometer. If the detected signal is substantially similar to the high frequency signal channeled through the positive lead, the integrity of the accelerometer is verified.
