second), and KNT (knots).
In temperature mode, you can choose between °F and °C.

the battery (CR2032) into the battery compartment with the “+” side
out. Place the battery cover back and lock it with a coin.
Caution
The meter is accurate at low and mid-range air speeds. Consistent
use at high speeds, such as from the window of a fast-moving car,
will damage the impeller’s bearing and reduce accuracy.
