Accept New Sensor Type
When replacing EC cells or mV sensors, use Accept New Sensor
Type to load default parameters into the XNX transmitter for
calibration and sensor life. Accept New Sensor Type is also used
when replacing an EC cell with another EC cell for a different
target gas. (See Section 4.2.2).
