X • Set the following exposure parameters and initiate an exposure after each setting:
PMF kV accuracy 52 kV, 50 mAs
PMF kV accuracy 81 kV, 20 mAs
PMF kV accuracy 133 kV, 12.5 mAs
Record the measured values.
Oscilloscope method:
"KVS" measuring point for the nominal value and “KV” measuring point for the actual
value. The measuring ratio is 30 kV/V.
• Open the top system cover and place the cover sideways on a table or the like. Do not
disconnect any cables.
