This process will calibrate the internal noise gain.
PROCESS:
1. Turn the module On and wait about 30 seconds for it to stabilize
2. Patch the “NOISE” Output to an oscilloscope
3. Adjust the trimmer until the level peaks at about ±5 volts.
The ±5 volt calibration is just a reference, the user can calibrate it
to any other range according to his wish.
