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