11
Setting of 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 is expressed as a
number of tenths (e.g. 5 = 0.5 µg/m
3
). If the output is asso-
ciated to CO
2
, the value is expressed as a number of units
(e.g. 200 = 200 ppm). The default value is 0.
32-bit Integer
13
Setting of 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 is expressed as a
number of tenths (e.g. 50 = 5.0 µg/m
3
). If the output is as-
sociated to CO
2
, the value is expressed as a number of units
(e.g. 800 = 800 ppm). The default value is 10000 (=1000.0
µg/m
3
of PM).
32-bit Integer
15
Setting of the PM measurement mode:
0=continuous;
1=at cyclic intervals (default).
16-bit Integer
16
Setting of the cycle interval, in seconds, for the PM meas-
urement mode at cyclic intervals.
The default value is 300 (=5 min).
16-bit Integer
Unsigned
18
Setting of the sensor ON time, in seconds, for the PM
measurement mode at cyclic intervals.
It must be greater than 70 s (warm-up time).
The default value is 71.
16-bit
Unsigned Integer
19
Setting of the type of PM measurement averaging for the an-
alog outputs and the measurements sent by the transmitter
in reply to P1, P5, S1 and S5 commands (proprietary proto-
col) or when reading MODBUS Input Registers 0…5:
0=average over a 10 seconds interval, updated every sec-
ond;
1=average over a 60 seconds interval, updated every 10
seconds (default);
2=average over a 15 minutes interval, updated every mi-
nute.
16-bit Integer
20
Setting of the type of CO
2
calibration to be used:
0=user;
1=factory (default).
16-bit Integer
For 32-bit values, two consecutive registers must be accessed (e.g. 6 and 7 for the setting of
the minimum value of the measuring range of the physical quantity associated to the analog output
1). The register with lower address contains the most significant bits.
