Calibrating your Microphone:
1. Measure the calibration signal first.
This is done by using an acoustic
calibrator that generates a 94dB at 1
kHz. The user inserts one of the
microphones into the acoustic
calibrator chamber.
2. A spectrum measurement is taken.
3. The user then moves the cursor to 1
kHz.
4. Now the user selects the calibration
pop-up window as shown to the left.
5. Now the X-Axis will show 1 kHz,
because the user has moved the
cursor to 1 kHz.
6. The old value will show the existing cursor position at 1 kHz.
7. Now the user enters the NEW VALUE using the
[Navigation Keypad]
.
Normally, this is 94dB as shown on the calibrator. So, the user would then
enter 94 for the new value.
8. Press OK.
