Outdoor Microphone
Calibration
The design of the M2230-WP Outdoor Measurement Micro-
phone supports easy calibration of the microphone. To cali-
brate, follow the procedure below:
The top section of the M2230-WP is snapped on to
•
the body tube. Remove the top section of the M2230-
WP by gently pulling the bird spike upwards. At the
same time gently push up on the cage inside the wind
screen with two fingers of your other hand. You will
feel when the snap mechanism is released.
The snap mechanism works only at tempera-
tures above -15°C / 5°F (as the O-Ring stiffens).
In colder conditions we suggest you warm up
the housing first, e.g. with your hands.
Gently remove the top section.
