Command Reply Description
CA2Hn &| Sets n as the maximum value of the measuring range of
the physical quantity associated to the analog output 2.
If the output is associated to PM, the value must be ex-
pressed as a number of tenths (e.g. n=50 to indicate 5.0
µg/m
3
). If the output is associated to CO
2
, the value must
be expressed as a number of units (e.g. n=800 to indicate
800 ppm).
Default : 10000 (=1000 µg/m
3
of PM)
RA2H & n| Reads the maximum value of the measuring range of the
physical quantity associated to the analog output 2.
