HYGROMETER FUNCTIONS

Both the main unit and the sub-unit are equipped with their own humidity sensors. Humidity data measured by the sub-unit is sent by wireless transfer to the main unit. You can toggle the main unit display between the main unit humidity reading and the sub-unit humidity reading. This makes it possible to view both the indoor and outdoor humidity on the main unit display.

Humidity Measurements

•Both the main unit and the sub-unit take humidity measurements every 16 seconds.

•The humidity display shows “LO” for humidity below 10% and “HI” for humidity above 90%.

Switching between Main Unit and Sub-unit Humidity Data

•Press the SELECT button (B) to toggle the display between the main unit (INDOOR) humidity and the sub-unit (OUTDOOR) humidity .

Main unit humidity: INDOOR indicator displayed

Sub-unit humidity: OUTDOOR indicator displayed

•The display does not change to the sub-unit (OUTDOOR) humidity if no data has been received from the sub-unit yet.

•Holding down SELECT button (B) for about two seconds causes the display to continually toggle between the main unit and sub-unit humidity at five-second intervals.

USING THE SUB-UNIT

Data Transfer from the Sub-unit

•Data is transferred from the sub-unit to the main unit every three minutes.

•The sub-unit is able to send data to the main unit up to an unobstructed distance of about 30 meters.

•The data receive status is indicated on the display of the main unit by the icons shown below.

Receive successful

Receive unsuccessful

•If a receive operation is not successful for some reason, the display of the main unit shows dashes (–) in place of the sub-unit temperature and humidity values.

•If you experrience problems with data transfer, press the RE-SYNC button (A) to synchronize the two units.If this does not eliminate the problem,try changing the positions or orientations of the main unit and sub-unit.

•The transferred data includes temperature and humidity data.

Switching between Celsius and Fahrenheit

•Push the °C/ °F button (F) to toggle between Celsius (°C) and Fahrenheit (°F).
