;Program Author: Campbell Scientific, Inc.
;Date: 04-12-06
;Description:
Program measures 1 EnviroSMART / TriSCAN probe with 8 sensors or 1 EasyAG
;
TriSCAN probe with 4 sensors. -1000 is loaded as the "measurement" for
;
non-existant sensors. Program measures scaled frequencies, calculates
;
water contents, and stores scaled frequencies, water contents, and
;
volumetric ion contents separately. Scaled frequencies are stored with an
;
"array identifier" leading 8 data values per record followed by 8 VIC per
;
record, with the record ending with zero rain and irrigation values for
;
compatibility with DBLOAD & Irrimax software.
;Assumptions:
EnviroSMART or EasyAG probe SDI-12 interface is configured to output
;
scaled frequencies
