Note: This command will affect the detector's calibration.
Several detector parameters are available for
monitoring purposes. These include GAS CONC (Point
4), ALR LO FLAG (Point 90) and ALR HI FLAG (Point
91). These points can be unbundled for monitoring or
used in various global control strategies.
91). These flags are ON when the gas concentration
exceeds alarm levels. For example, these flags can be
used to start ventilation or activate a buzzer.
CMD SET ZERO (Point 23) is the command used to
calibrate the zero of the sensor, which is the reference
for the detector when no GAS is present. When
ordered, this point will return to STOP by itself and it's
initial value cannot be changed.
CMD SET SPAN (Point 22) is the command used to
calibrate the sensor with a specific gas concentration.
The concentration applied to the detector is specified in
the GAS SPAN (Point 6) field. When ordered, this point
will return to STOP by itself and it's initial value cannot
be changed.
