HOW TO ADJUST THE ADC
The ADC setup menu positions allow the ambient noise signal level to be monitored and then
adjusted to move symmetrically about 0v, normally this will be factory adjusted. Any adjustments
must be made before product calibration.
If adjustment of either channel is required, for instance when a board is replaced the following
steps should be followed:
•
Select an unused memory position and ensure the "Head power" found under "Manual setup"
is set to MAX.
