CAUTION
Your

to
provide accu

Depending
on
your
location
and
environm
ent, conditions may
change rapidly
.
Rapid
temperature
and
humidity
changes (i.e., moving
your
meter from i
ndoors
to outdoors)
may
cause inaccurate readings of te mp
erature
artd
humidity
, as
well
as
all
readings
that
rely on
erther
of
these vafues. Before relying
on

To
maximize
t he
accuracy
and reliabili

of
your
readings:
Ensure t

to
stabilize
a h
er significan
t changes in t
emper
atur

humidity
(i.e., chan9i

ation
from
in
doors to
outdoors).
Allow a margin
of
safety
for changing conditions
and
reading
errors (2-3%
of
reading
is recomme
nded
).
Use
extra
care
and
