Thank you for purchasing a Silicon Pyranometer Sensor

to use with your WatchDog Weather Station or Data
Logger, or your Field Scout Light Sensor Reader.
Item 3670I is for general use, while item 3670WS2 is de-
signed as a replacement sensor for the WatchDog
2900ET or 900ET Weather Stations.
The sensors measure solar
radiation between 300 and
1100 nanometers. This range
is important for evapo-
transpiration calculations.
This manual will aid you in
placement and mounting of
the sensor. Read it
thoroughly to insure proper
and effective use.
Use With a Field Scout
Light Sensor Reader
You may wish to remove the mounting bracket when us-
ing the silicon pyranometer sensor with a Field Scout
Light Sensor Reader. If so, loosen the thumbscrews, and
save the parts for reassembly.
Just plug the sensor into the reader, and SET the reader
to "SOLR RAD". For more details, see the Field Scout
Sensor Reader Manual.
Use With a WatchDog
Station or Logger
The 3670WS2 Silicon Pyranometer replacement sensor
includes a 20 in (50cm) data cable which is plugged into
Port F on a 2900ET or Port D on a 900ET weather sta-
tion. Use the existing thumbscrews to remove the old
sensor, and attach and level the replacement.
