Read Analog Input “R”
The read-analog command has a form for reading a specified analog input
channel, a form for auto-calibrating the gain of the analog circuits, and a form for
defining the averaging period for analog readings.
The analog channels are not related to the circuits used for the current and
voltage readings. The analog channels refer to the irradiance (pyranometer), and
temperature readings as well as auxiliary analog port, and internal readings such
as battery voltage.
Format
Option 1
“R,n1,n2”
Read input n1 (0-13).
n2 = Pyranometer constant in W/m2 / volt.
Only needed if n1 = 2 or 3.
Option 2
“R,C”
Calibrate analog board circuits.
Option 3
“R,P,t”
Set analog averaging period ‘t’ in
microseconds.
Option 1 reads one of 14 possible analog inputs. It returns a numeric value for
the channel.
