SGP/EEBR/E2 - Soil Temperature #2 Incorrect

Soil temperature #2 was intermittently incorrect.
The cause is not yet known.  The indicated other measurements
were also incorrect because soil temperature #2 was used in the
calculations of the quantities.

Soil moisture (30 minute only) was affected because version 6
of the EBBR datalogger program used a multiplication of
soil temperature and soil moisture as part of the adjustment
of soil moisture for soil temperature.  This was discovered
to be a poor technique soon after it was implemented, but E2
will continue to use version 6 until a replacement EBBR unit
is available.

Changeout dates of the EBBR units can be found on the EBBR
Instrument web page.
