1. Find a time period in which no humans will be
present in a well-ventilated room overnight
(7-8 hours).
2. Remove the plastic face shield from the meter.
This step is important because the shield blocks
the internal sensors.
3. Plug the power cord into the micro USB port and
turn the meter on. The meter can be powered by a
computer’s USB port or any cell phone power block
during first-time set-up.
4. The screen displays “Loading” and a status bar will
briefly display on the main screen.
5. When the meter powers on, both the humidity
and the CO
2
readings will be inaccurate. This
is normal due to the air trapped in the housing
during storage.
6. Leave the meter in a well-ventilated room
overnight to allow the humidity and CO
2
readings
to stabilize overnight.
7. The meter is now ready for use and can be
operated with or without the power cord.
