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.

操作指南
開機、關機
按“ ”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
