4Adjustment or Calibration
Note: The measured humidity range is between 10 and 99%. Humidity cannot be
accurately measured outside of this range. Thus, the humidity cannot be calibrated
below 10% or above 99%.
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.
4.1 Humidity Calibration
To enter the humidity calibration mode, press and hold the SET and MIN/MAX buttons at
the same time for 3 seconds and the humidity value will begin flashing. Press the CH/+
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 CH/+ or MIN/MAX/- button.
To return the humidity to the actual or uncalibrated measurement, press the SET button.
will be displayed when the humidity reading is a calibrated one.
After calibration is finalized, press and hold the SET button for three seconds, or wait 15
seconds for timeout, and the humidity value will stop flashing.
4.2 Temperature Calibration
To enter the temperature calibration mode, press and hold the SET and CH/+ buttons for
3 seconds and the temperature value will begin flashing. Press the CH/+ button to
increase the temperature and the MIN/MAX/- button to decrease the temperature
reading in 0.1° increments. To rapidly increase (or decrease) the temperature reading,
press and hold the CH/+ or MIN/MAX/- button.
To return the temperature to the actual or uncalibrated measurement, press the SET
button. will be displayed when the temperature reading is a calibrated
one.
After calibration is finalized, press and hold the SET button for three seconds, or wait 15
seconds for timeout, and the temperature value will stop flashing.

Discussion:Temperature errors can occur when a sensor is placed too close to a
heat source (such as a building structure, the ground or trees).
To calibrate temperature, we recommend a mercury or red spirit (fluid) thermometer. Bi-
metal (dial) and other digital thermometers are not a good source and have their own
margin of error. Using a local weather station in your area is also a poor source due to
changes in location, timing (airport weather stations are only updated once per hour) and
possible calibration errors (many official weather stations are not properly installed and
calibrated).
Place the sensor in a shaded, controlled environment next to the fluid thermometer, and
allow the sensor to stabilize for 48 hours. Compare this temperature to the fluid
thermometer and adjust the console to match the fluid thermometer.
4.3 Sensor Operation Verification
Verify the humidity match closely with the console and sensor array in the same location
(about 5 to 10’ apart). The sensors should be within 10% (the accuracy is ± 5%). Allow
about 30 minutes for both sensors to stabilize.
Verify the temperature match closely with the console and sensor array in the same
location (about 1.5m to 3m apart). The sensors should be within 2°C(the accuracy is ±
1°C). Allow about 30 minutes for both sensors to stabilize.
4.4. Indoor Sensor Installation
Indoor use only. It is recommended you mount the Indoor sensor on a north
facing wall, in a shaded area. Direct sunlight and radiant heat sources will result
in inaccurate temperature readings. Use a screw or nail (not included) to affix the
indoor sensor to the wall, as shown in Figure 4.
Figure 4
Or put it on the table. Place the console at least three feet away from computers, TVs
and wireless phones. Avoid transmitting through solid metal barriers. as shown in Figure
5.

Figure 5
4.5 Best Practices for Wireless Communication
Wireless communication is susceptible to interference, distance, walls and metal
barriers. We recommend the following best practices for trouble free wireless
communication.
1. Electro-Magnetic Interference (EMI). Keep the console several feet away from
computer monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 433.9MHz 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 100 meter line of sight (no
interference, barriers or walls) but typically you will get 30 meter 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. If you have metal siding, align the remote and console through
a window to get a clear line of sight.

Problem
Solution
Wireless remote (thermo-
hygrometer) not reporting in to
console.
If any of the sensor communication is lost,
The maximum line of sight communication range
is 100 meters and 30 meters under most
conditions. Move the sensor assembly closer to
the display console.
If the sensor assembly is too close (less than 5’),
move the sensor assembly away from the display
console.
Make sure the remote sensor LCD display is
working and the transmitter light is flashing once
per 48 seconds.
Install a fresh set of batteries in the remote
thermo-hygrometer. For cold weather
environments, install lithium batteries.
Make sure the remote sensors are not
transmitting through solid metal (acts as an RF
shield), or earth barrier (down a hill).
Move the remote sensors around electrical noise
generating devices, such as computers, TVs and
other wireless transmitters if used indoor.
Move the remote sensor to a higher location.
Move the remote sensor to a closer location.
Temperature sensor reads too high
in the day time.
Make sure the thermo-hygrometer is mounted in a
shaded area on the north facing wall.
Indoor and Outdoor Temperature do
not agree
Allow up to one hour for the sensors to stabilize
due to signal filtering. The two temperature
sensors should agree within 2 °C (the sensor
accuracy is ± 1 °C).
Indoor and Outdoor Humidity do not
agree
Allow up to one hour for the sensors to stabilize
due to signal filtering. The two humidity sensors
should agree within 10 % (the sensor accuracy is
± 5 %).
Display contrast is weak
Replace console batteries with a fresh set of
batteries.
