A wind screen is attached to the Sound Level Meter (LA-1240/1250/1350/4350) to reduce measuring errors such as those due to strong wind. Use the wind screen for measurement of a ventilating fan or measurement performed outdoors where the microphone is exposed to direct strong wind.
How to attach the wind screen
Insert the wind screen slowly and gently into the hole for the windshield screen until the end of the microphone makes contact after turning off the power of the sound level meter. When using a wind screen outdoors continuously for a long period of time, please purchase an all-weather wind screen that is sold separately.
Make sure that no impact is applied to the microphone when removing or installing a wind screen.
