Claim 3:
4. A system, comprising:
at least one sensor for detecting an analyte gas; and
a control system, the control system being configured to electronically interrogate the at least one sensor by application of an electronic interrogation signal to the at least one sensor and measuring a response thereto without application of a calibration gas comprising either a known concentration of the analyte gas or a simulant therefor to the sensor to determine the operational status thereof, the control system further being configured to change at least one reporting parameter of the at least one sensor on the basis of results of electronically interrogating the at least one sensor, wherein the at least one reporting parameter which the control system is configured to change is a range, a resolution, a cross-sensitivity parameter, a set point, or an alarm signal.
