The Analog Database setup is almost identical to that of the relays.
QIRF will compare the concentration at 4mA and the concentration at 20mA, you may
assign a larger concentration for 4.0 milliamps than for 20 milliamps; the QIRF will still
stretch a straight line signal between the two points and then convert the current gas
reading to analog output.
Note: The Analog Output can not be disabled.
Note: When the sensor has fault, it will output 2.5mA to indicate fault status.
Conc@4mA:
Input the gas concentration at which the 4mA is output.
Default is 0 ppm.
Conc@20mA:
Input the gas concentration at which the 20mA is output.
Default is 1000 ppm.
