B.1 CR1000 Programs
B.1.1 CR1000 with One CS650 Probe
This CRBasic example program measures one CS650 probe on a CR1000
every 15 minutes, storing hourly averages of volumetric water content,
electrical conductivity, and soil temperature and samples of permittivity, period
average and voltage ratio. The CS650 has an SDI-12 address of 0. Wiring for
the example is shown in TABLE B-1.

B.1.2 CR1000 with Two CS650 Probes on Same Control Port
This CRBasic example program measures two CS650 probes on a CR1000
every 15 minutes, storing hourly averages of volumetric water content,
electrical conductivity, and soil temperature and samples of permittivity, period
average and voltage ratio. The first CS650 has an SDI-12 address of 0 and the
second has an address of 1. Wiring for the example is shown in TABLE B-2.
Assignment of aliases and units is not shown in this example.
