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%.
