What are the Self-Test features available with the QRS11?
The Model QRS11 Quartz Rate Sensor incorporates dual self-test circuitry to determine the functionality of the unit, for both monitoring and for failure detection. An individual Built-In-Test (BIT) signal is produced by the drive system. The BIT signal provides a continous monitor indicating that the QRS11 sensing element is functioning properly. To provide a definitive test of the remainder of the signal processing circuitry, a Self-Test Input is provided. An external voltage signal applied to the Self-Test input will command a specific change in the Rate Output. The expected change in the Rate Output indicates that the entire signal processing chain within the QRS is performing properly.
