When measuring at the 2nd and 3rd opening of the top row, a
voltage of +5.5 V ± 0.2 V should be able to be measured.
6.
In the event of a fault with the QCC interface card, one or both
voltages cannot be measured. The QCC interface card is thus
defective and must be replaced.
If both voltages can be measured, the voltage supply from the QCC
interface card is OK and a malfunction should be searched for on
the CEREC Primescan / Primescan scanner.
