Operating guidance

PowerOn/Off

Press the “ ” keytoturnonorofftheanemometerpower.

Readinghold

In the measurement process, if the reading should be kept,

press "HOLD" key to lock the reading, and display the HOLD

symbol; press itagaintounlock.

Note:

In the reading hold state, “FUNC”, “MAX/MIN” and “UNIT” keys

areinvalid.

Backlight

In themeasurement 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

" "keyagaintoturnoffbacklightatanytime.

Note:

TheluminousbodyofbacklightisLEDwithlarge

operatingcurrent.Frequentlyusing backlight willshorten

batterylife.Donotusebacklightwhenunnecessary.

When the battery voltage ≤ 7V, the " " (low battery)

symbolwillshowonthedisplay.However, inthecase

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 fansurfaceperpendicularlytothewinddirection.

Note:

‧Ifthedetector (fan) isnotaimingatthewinddirection, which

will bringthemeasurementerror.

‧For steady wind, the detector (fan) will register maximum

readingwhenitisaiming atthewinddirection.

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).

Areasetting

To measure air volume, you should first determine the area of

airflowtobe,inputstepsareshownasfollowing:

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．Tochangetheareasetting,pleaserepeatthestep②.

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"symbolshoulddisplayonthescreen.

Measurement is done withthe fan surface perpendicular to the

wind direction.

Note:

‧Ifthedetector(fan)isnotalignedinthewinddirection,the

measurementcan beskewed.

‧Forsteadywind,thedetector(fan)willgetmaximumreading

Air volume unitselection

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

shouldbereplaced.

‧Poweroff themeterandremovethebatterycover.
