5-2 The Windscreen and Microphone

During use, it is essential that the meter is fitted with the Windscreen. The
Windscreen protects the microphone from potential erroneous results due to air
movement passing over it but also helps to protect from dust ingress, moisture or
minor impact damage.
To calibrate the meter it is necessary to remove the Windscreen to expose the
microphone. To unscrew the Windscreen by turning the black ring (not the foam!)
in a anticlockwise direction.
It will not normally be necessary to remove the Microphone but to do so unscrew
anticlockwise direction. When refitting the Microphone, screw the Microphone on
clockwise until it fits tightly.
Following calibration refit the Windscreen, screw the Windscreen in a clockwise
and take care do not over tighten; finger tight is sufficient.
