The cGas Detector has built in fault detection, and in the event of a problem
with the measurement circuitry the transmitter will indicate a fault condition
on the display. Normal operation will resume once the fault condition has been
corrected.
NOTE:
If a question mark ? is displayed, the system is reading slightly negative
but not enough to adversely affect the alarm functionality; a re-zeroing is
recommended.
