SECTION 3. PROGRAMMING
The CR10 Measurement and Control Module begins executing the program stored in its PROM when
power is connected to the weather station. This "program-on-power-up" function is not found in standard
CR10s where users enter their own programs. Users desiring additional sensors or outputs different
from this "standard" program may create their own program and overwrite the existing one.
The resident program listed in Appendix A measures wind speed, wind direction, air temperature,
relative humidity, solar radiation, and rain every 10 seconds. Soil temperature is measured only if
enabled by the user; Flag 1 = 1 (Section 2.9).
The program stores hourly, daily and conditional data as shown below.

3.1 PROGRAMMING SENSOR
MEASUREMENTS
The instructions used to measure and convert
sensor signals to the values displayed in Input
Memory (*6 Mode) are discussed in the
following pages. The standard sensors are
assigned fixed CR10 Input Channels and
Excitation Ports. These and other
measurement parameters used in the program
are summarized in Table 3-2.
