The dark calibration test interrupts the signal path between the IR photo-detector
and the remainder of the sync/demod board circuitry. This allows the instrument
to compensate for any voltage levels inherent in the sync/demod circuitry that
might effect the calculation of CO
returns two offset voltages, One for CO
automatically added to the CPU's calculation routine. The two offset voltages
from the last calibration procedure may be reviewed by the user via the front
panel display.
To activate the dark calibration procedure or review the results of a previous
calibration, press:
