kV Calibration
During a 75kV manual fluoro exposure,
adjust R28 for 7.5 vdc on TPf (see page 2)
on the B54 board. Verify that there is 3.6 vdc
on TPf during a 36kV exposure and 10.0 vdc
during a 100kV exposure. You can measure kV
with the Keithly Triad System, using the wide
range filter pack or with the Victoreen 4000+.
