Evaluating test values
PMF
Anode acceleration
•
Listen to the sound generated by the accelerating anode. Is the sound normal?
PMF
kV and mA
•
Do the measured kV and mA values agree with the values selected?
PMF
mAs selection
•
Do the measured mAs values agree with the values selected?
PMF
mAs value displayed
•
Does the mAs value measured agree with the mAs value displayed (for AEC)?
PMF
Grid voltage
•
Attach the magnification table. Measure the grid voltage (small focus) on tube test point
G against test point H
3
. Does the value measured agree with the value in the test proto-
col?
•
Test both focal spots (if available).
PMF
Signal lamp
•
Does the radiation-ON indicator light up?
PMF
