6.
Select 75 kVp, 200 mA.
Select the exposure times shown below (3
point operation).
(Measure time and mA on the ‘scope and
check that their product is as per the RESULT
column).
Measure time at 75% of the peak kVp
waveform.
A: 10 ms (2 mAs)
B: 20 ms (4 mAs)
C: 63 ms (12 mAs)
D: 100 ms (20 mAs)

kVp.
Select the mAs shown below (2 point
operation).
Measure time at 75% of the peak kVp
waveform.
A: 2 mAs (time per LCD display)
B: 8 mAs (time per LCD display)
C: 25 mAs (time per LCD display)
D: 63 mAs (time per LCD display)
NOTE: The time associated with
each mAs setting will vary
depending on generator
configuration.
Use the time displayed in the
LCD window as the reference
