Operating guidance Power On/Off
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.
Page 9

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:
Press “FUNC” key to make “AREA” display on the screen. 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.
.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.

操作指南
開機、關機
“ ”鍵可將風速表電源開機或關機。 讀數保持
在測量的過程中,如需要讀數保持,按下“HOLD”鍵可
鎖定讀數,並顯示符號HOLD;再按一次可解除鎖定。 在讀數保持時,“FUNC”及“MAX/MIN”、“UNIT”鍵功能
將失效。 背光源
在測量的過程中,如果環境光線太暗,致使讀數困難, 可按動 ”鍵,打開背光源。背光源的定時時間為 15 秒,在此期間可隨時再次按動 ”鍵關閉背光源。
注意:
1. 背光源的發光體為LED,其工作電流較大,經常使
用背光源將縮短電池的壽命,所以非必要的情況
下,應儘量少用背光源。
2. 當電池電壓7V 時,顯示器顯示 (欠壓)符
號。但在使用背光源的情況下,在電池電壓7V 時,由於其工作電流較大,使電池電壓下降, 符號可能顯示( ”符號顯示時,不保證測量的

準確度),這時可不更換電池,在不用背光源的情 況下正常使用直到 符號顯示再行更換。
風速測量
將探測器(風扇)放到被測環境,螢幕顯示“VEL”符號,
風扇平面垂直對準風向進行測量。
注意:
1. 若探測器(風扇)未對準風向,會帶來測量誤差。
2. 對大小穩定的風,探測器(風扇)對準風向時測得
的讀數最大。
風速單位選擇
儀錶風速測量時,可按“UNIT”鍵,選擇您所需要的測
量單位元(m/s、km/h、mill/h、ft/s、ft/m、knots)。
面積設置
要測量風量,必須先確定被測風道的面積,面積輸入
步驟如下:
.按“FUNC”鍵,使螢幕出現“AREA”.按“MAX/MIN”和“UNIT”兩鍵調整數值和單位,調 整完面積單位(、ft²)後再按“MAX/MIN”鍵將聽到
Page 22

連續兩聲嗡鳴聲,表示面積輸入結束並已保存。 .更改面積設置,請重複步驟②。
風量測量
將探測器(風扇)放到被測環境,通過“FUNC”鍵使螢 幕顯示“FLOW”符號,風扇平面垂直對準風向進行測
量。
注意:
1. 若探測器(風扇)未對準風向,會帶來測量誤差。
2. 對大小穩定的風,探測器(風扇)對準風向時測得
的讀數最大。
風量單位選擇
儀錶風量測量時,可按“UNIT”鍵,選擇您所需要的測
量單位元(CMS、CMM、CFM)。
