Program
Number Program Description
1 Set Flag 1 to read output of one CS616 using CR10X instruction
138 and convert output period to volumetric water content
2 Every 5 minutes, measure CS616 output period using instruction
27 and convert to volumetric water content. Write hourly
average to datalogger final storage.
3 Read datalogger battery voltage and 3 CS616s hourly. Convert
CS616 period to volumetric water content. Write average of
hourly readings to final storage every 4 hours.
4 Measure soil temperature and CS616 output period every 4
hours. Correct CS616 output period for temperature and write
result to datalogger final storage.
5 Hourly, measure datalogger battery voltage, internal temperature
and 48 CS616 probes using AM16/32 multiplexer.
