3. Select Next to proceed with the first (50) kVp calibration, or you may
select a particular kVp Calibration to perform by selecting its correspond-
ing tab (choices are 50 kVp and 100 kVp). For this example, "50 kVp" is
selected, as shown below:

4. Connect a kVp bleeder tank in series between X-ray tube and the genera-
tor’s H.V. Transformer (A17), or use a non-invasive kVp meter.
5. Take an exposure at the setting indicated on the 50kVp Calibration
Screen (i.e., 50 kVp, 200L mA, 100 msec).
6. On the kVp meter, observe the measured kVp value. Enter the actual
(measured) value by adjusting the slide control, or by selecting the data
entry box and typing the value using a keyboard. The value entered
should be to the hundredths decimal place. Press Calibrate button.
7. Ideally, the value appearing in the 50 kVp Calibration Screen (Step 1.) will
match the reading on the kVp meter within allowable tolerance. If so,
press the Confirm button. The calibration value is saved and the system
advances to the 100 kVp Calibration setting.
