Press the “ ” key to turn on or off the anemometer power.
Reading hold
In the measurement process, if the reading should be kept,
press "HOLD" key to lock the reading, and display the HOLD
symbol; press it again to unlock.
Note:
In the reading hold state, “FUNC”, “MAX/MIN” and “UNIT” keys
are invalid.
Backlight
In the measurement process, if the ambient light is too dark to
read, you can press "" key to open the backlight. Backlight
timer is set to 15 seconds. During this period, you can press
"" key again to turn off backlight at any time.
Note:
The luminous body of backlight is LED with large
operating current. Frequently using backlight will shorten
battery life. Do not use backlight when unnecessary.
When the battery voltage ≤ 7V, the "" (low battery)
symbol will show on the display. However, in the case
of using the backlight, if the battery voltage ≥ 7V, the battery
voltage drops because of its larger operating current, ""
symbol may show (when "" symbol is showing, the
accuracy of the measurement can’t be guaranteed). At this
moment, you needn’t replace battery until the "" symbol
display again under normal use condition without using
backlight.
Wind speed measurement
Place the detector (fan) into the test environment, "VEL"
symbol will display on the screen, measurement is done with
the fan surface perpendicularly to the wind direction.

Note:
‧If the detector (fan) is not aiming at the wind direction, which
will bring the measurement error.
‧For steady wind, the detector (fan) will register maximum
reading when it is aiming at the wind direction.
Wind speed measurement
When using the meter to measure air volume, you can press
“UNIT” key to select the measurement unit you required (m/s,
km/h, mill/h, ft/m, ft/s, knots).
Area setting
To measure air volume, you should first determine the area of
air flow to be, input steps are shown as following:
①.Press “FUNC” key to make “AREA” display on the screen.
②.Use the “MAX/MIN” and “UNIT” keys to adjust value and
unit, after adjusting area unit (m², ft²), then press
“MAX/MIN” key. There should be an audible buzz,
indicating that area input is completed and settings are
saved.
③.To change the area setting, please repeat the step ②.
Air volume measurement
Place the detector (fan) into the test environment. Use the
“FUNC” key to set the meter to the Air volume measurement
mode; the "FLOW" symbol should display on the screen.
Measurement is done with the fan surface perpendicular to the
wind direction.
Note:
‧If the detector (fan) is not aligned in the wind direction, the
measurement can be skewed.
‧For steady wind, the detector (fan) will get maximum reading
when it is aiming at the wind direction.

Air volume unit selection
When using the meter to measure air volume, you can press
the “UNIT” key to select the measurement unit
you require (CMS, CMM, CFM).
Replacing battery
‧If the “” sign appears, this indicates that the battery
should be replaced.
‧Power off the meter and remove the battery cover.
‧Replace the old battery.
‧Install the battery cover properly.
