Airflow functionality
(Available using Quest's Air Probe on QUESTempº 46 model only)
Airflow is measured in meters per second over a range of 0 to 20m/s in 0.1m/s
increments. The sensor should be placed or held perpendicular in the air stream.
Unlike many anemometers, the omni-directional sensor does not require rotating to
find the maximum reading. Be careful not to block the airflow with your body
during measurements. The sensor's measuring tip is fragile; be cautious if
measuring in ducts.
The Air Probe may be either hand held or mounted behind the QUESTemp 46
using the mounting bracket hooked to the sensor bar beneath the center bulb
sensor. (See Figure 1-22 below.)
A green lamp indicator in the Air Probe indicates that it is turned on and the
battery is good. If the green indicator turns off while the switch is in the On
position, replace or recharge the battery.
