Sample Programs
You can use the following examples with data loggers from Campbell
Scientific. The first program is for a CR1000 data logger, but can
be easily adapted for other “CRBasic” type loggers. The second
program is for a CR10X data logger, but can be easily adapted to
other Edlog type loggers. The 10HS needs 3 to 15 V DC excitation,
and therefore cannot be excited with the 2.5 V excitation port of
many Campbell Scientific data loggers.
We recommend that the
switched 12 V or CAO port be used to excite the 10HS.
