TAG INSTALLATION
The tag is housed in a rugged metal that can withstand harsh environments. However, it is better
to protect the tag from direct rain.
Place the tag near a sampling point. Fix it securely with the provided screws, in such a way that
the metallic iButton
® is easily accessible for reading the tag.
The number of tags that can be installed is practically unlimited. Additional tags can be ordered
(
HI 920005 - five tag holders with tags).

from the lamp holder handler.

to be recalibrated.
