7.13.1 Verification of Exposure parameters with invasive
method
The exposure parameters (kV, mA and exposure time) can be measured directly on
the Generator board (A2); this method has higher accuracy than the so-called non-
invasive mode. The system accuracy is guaranteed by this measuring method.
Warning
By removing the HF group covers, internal parts where high voltage is
present become accessible.
The Generator board has a working voltage of about 400V.
The exposure parameters can be checked with the following procedure:
1. Turn OFF the system.
2. Remove the cover on the back of the generator and remove the protection grid
of the HF board.
3. Identify the test point XJ8.
