Command Reply Description
CA1Hn &| Sets n as the maximum value of the measuring range of
the physical quantity associated to the analog output 1.
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 (=1000.0 µg/m
3
of PM)
RA1H & n| Reads the maximum value of the measuring range of the
physical quantity associated to the analog output 1.
RA1F & Quantity
Minimum value
Maximum value
Simultaneously provides the information obtainable with
the RA1T, RA1L e RA1H commands.
CA2On &| Enable/disable the offset of the analog output 2:

Offset disabled if n=0 (0…20 mA or 0…10 V)

Offset enabled if n=1 (4…20 mA or 2…10 V)
Default : Offset enabled (n=1) if the output is current,
offset disabled (n=0) if the output is voltage (optional)
RA2O & n| Reads the setting of the offset for the analog output 2.
CA2SOn &| Sets the direct or inverse correspondence between analog
output 2 and associated physical quantity:

4 mA/0 V

Min. quantity, 20 mA/10 V

Max.
quantity if n=0

20 mA/10 V

Min. quantity, 4 mA/0 V

Max.
quantity if n=1
Default
: Direct correspondence (n=0)
RA2SO & n| Reads the type of correspondace (direct or inverse) be-
tween analog output 2 and associated physical quantity.
CA2Tn &| Associates the analog output 2 to:

PM1.0 if n=0

PM2.5 if n=1

PM10 if n=2

CO
2
if n=12 (only PMBsense-A)
Default
: PM10 (n=2)
Note: the PM measurement is updated according to the op-
erating mode set with the CPLS, CPLP and CPS commands.
RA2T & n| Reads the physical quantity associated to analog output 2.
CA2Ln &| Sets n as the minimum 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=5 to indicate 0.5
µg/m
3
). If the output is associated to CO
2
, the value must
be expressed as a number of units (e.g. n=200 to indicate
200 ppm).
Default : 0
RA2L & n| Reads the minimum value of the measuring range of the
physical quantity associated to the analog output 2.
