4. PROGRAMMING
NOTE: Information in this section is not
necessary when programming the
MetData1 with the Short Cut Program
Builder software.
Solar radiation can be reported as an average
flux density (W m
-2
) or daily total flux density
(MJ m
-2
). The appropriate multipliers are listed
in Table 4-1. Programming examples are given
for both average and daily total solar radiation.
The output from the LI200X is 0.2 kW m
-2
mV
-1
.
4.1 AVERAGE SOLAR RADIATION
Example 1 shows the program instructions used
to measure the signal from the LI200X. A thirty
minute average is calculated and stored in final
storage.
