B.1.1 Example CR1000 Program Using Sequential Mode
This CR1000 program uses the sequential mode, which is the simplest mode
and can be used for most meteorological applications. Although the example is
for the CR1000, other CRBasic dataloggers, such as the CR200(X), CR800,
CR850, CR3000, and CR9000(X) are programmed similarly.
In the example, the CR1000 measures the CS106 once an hour. To do this, the
CR1000 uses a control port to turn on the CS106 one minute before the top of
the hour. On the hour, the datalogger measures the CS106, and then turns the
CS106 off. This example assumes that the jumper is in the default position
(open).
