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 calibrated measurement. Once the displayed humidity equals the calibrated source, 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 humidity calibrated measurement. Once the displayed temperature equals the calibrated source, 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 indoor and outdoor 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 indoor and outdoor 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 4
Figure 7 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.

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 %).
Problem Solution Display contrast is weak Replace console batteries with a fresh set of batteries.
