C.1.5 Temperature and Relative Humidity Probe
The
EasyFlux DL CR6CP
can support from zero to one temperature and
relative humidity probe. The default wiring for the HMP155A or EE181 is
shown in TABLE C-4 .
TABLE C-4 shows wiring for the HMP155A and EE181
temperature and humidity probes. Alternatively, an older model
probe such as the HMP45C or HC2S3 may be used, but wiring
for these models is not shown here. Instead, their wiring may be
found in the respective product manuals found at
www.campbellsci.com
. In any case, be careful to note the colors
of the wires and jumper wire configuration of the probe being
used. TABLE C-4 shows wire colors for the HMP155A and
EE181, where the colors for the EE181 are noted by italic text in
TABLE C-4 .

C.1.6 Radiation Measurements Option 1
There are two options for making radiation measurements with
EasyFlux DL CR6CP
. The program can support any combination of the four
sensors described in TABLE C-5 . Alternatively, it can support one of the two
types of four-way radiometers described in TABLE C-6 . TABLE C-5 gives the
default wiring for Option 1. TABLE C-6 shows the details of the default wiring
for Option 2.
