3.1 Calibration
To calibrate microphones in the EPS2116, follow these steps:
TAKE NOTE
The microphone
and preamplifier can be
pulled up if needed to allow
the microphone to seat fully
inside the calibrator, though
this is not necessary when
using the CAL200 or CAL250.
Step 1 Remove birdspike and windscreen by unscrewing the
assembly.
FIGURE 3-1 Remove birdspike
Step 2 Place the calibrator (CAL250 shown) on the microphone by
pushing down gently while slightly twisting clockwise.
