Irradiance, signal internal level and internal temperature
aM!
aC!
atttn<CR><LF>
with: ttt = number of seconds necessary for the in-
strument to make the measure available
(3 characters)
n = number of detected variables (1 character
for aM!, 2 characters for aC!)
Note: ttt = 000 means datum immediately available.
Request to execute the
measurement.
aD0!
a+n+w…w+v…v+t…t<CR><LF>
with:
n = content of the status register
w…w = irradiance in W/m
2
v…v = signal internal level in mV
t…t = internal temperature in the set unit of
measurement (default °C)
Example of response: 0+0+228.7+3.294+25.0
probe address = 0
content of the status register = 0
irradiance = 228.7 W/m
2
signal internal level = 3.294 mV
internal temperature = 25.0 °C
Note
: the status register normally contains zero; a
value different from zero indicates an error condi-
tion.
Reads the measurement.
