1. Electro-Magnetic
lnterference
(EMl). Keep
the console
several
feet away
from computer
monitors
and
TVs.
2. Radio
Frequency
Interference
(RFl).
lf
you
have other
433
MHz devices
and
communication
is intermittent,
try turning
off
these
other
devices for
troubleshooting
purposes.
You
may
need
to relocate
the transmitters
or
receivers
to
avoid
intermittent communication.
3.
Line of Sight
Rating.
This device
is
rated
at 90
meters
line of
sight
(no
interference,
barriers
or
walls) but
typically
you
will
get
30
meters maximum
under
most
real-world
installations,
which
include
passing
through
barriers
or walls.
4. Metal
Barriers.
Radio
frequency
will
not
pass
through
metal
barriers
such as aluminum
siding.
lf
you
have
metal siding,
align
the
remote and console
through
a window
to
get
a clear
line
of sight
.
5.6 Adjustment
or
Calibration
_--
Note: The
calibrated
value can
only be
adiusted
on the
console.
The
remote
senso(s)
always displays
the un-calibrated
or measured
value.
- -
Note: The
measured
humidity
range
is between
10
and 99%.
Humidity
cannot
be accurately
measured
outside
of
this range.
The
purpose
of
calibration is
to fine
tune or
correct
for any
sensor
error
associated
with
the devices
margin
of error.
The
measurement
can
be
adjusted
from the
console to calibrate
to a known
source.
Calibration
is only useful
if
you
have
a known
calibrated
source
you
can
compare
it against,
and
is optional.
This section
discusses
practices,
procedures
and sources
for sensor
calibration
to
reduce
manufacturing
and
degradation
errors.
Do
not compare
your
readings
obtained
from
sources such
as
the internet,
radio' television
or
newspapers.
They are in a different
location
and typically
update
once
per
hour.
The
purpose
of
your
weather station is to measure conditions
of
your
surroundings, which
vary significantly from location to location.
5.6.1 HumidityCalibration
Prior to
entering
the calibration
mode,
press
the CHANNEU+ button
to
select the humidity sensor
you
wish to
adjust.
To enter the humidity
calibration mode,
press
and hold the
ADJUST and MIN/MAX
buttons at the same time
for 5 seconds
and
the
humidity value
will begin flashing. Press the CHANNEL/+
button to
increase the humidity and the MIN/MAX/-
button to
decrease the humidity
reading in 1% increments.
To rapidly
increase
(or
decrease) the
humidity
reading,
press
and hold
the
CHANNEL/+ or
MIN/MAX/- button.
To return the
humidity to the actual or uncalibrated
measurement,
press
the ADJUST
button.
Once the displayed humidity equals the calibrated
source,
press
and hold the ADJUST
button for three seconds,
or wait 15
seconds for timeout,
and the humidity value will stop
flashing.
5.6.2
Temperature Calibration
Prior
to entering
the calibration mode,
press
the CHANNEU+
button to
select the temperature
you
wish to adjust.
To enter the temperature
calibration mode,
press
and
hold the
ADJUST butlon for 5 seconds and the temperature
value will begin
flashing. Press the CHANNEU+ button to increase
the temperature
and the
MIN/MAX- button to decrease the
temperature reading in
0.1'C increments.
To rapidly increase
(or
decrease)
the temperature
reading,
press
and hold
the CHANNEL/+ or MIN/MAX- button.
To return the temperature to the actual or uncalibrated
measurement,
press
the ADJUST
button.
Once the displayed
temperature equals the calibrated
source,
press
and hold the ADJUST
button for three seconds, or wait
15 seconds for
timeout, and the temperature
value will
stop
flashing.
