Calibration Verification
This step verifies that the previous calibrations have been properly performed and
that the generator is functioning correctly.
1. Connect Channel 1 of the scope to the "A + C" BNC output of the Dynalyzer™
2. Connect Channel 2 of the oscilloscope to the "mA" BNC output of the
Dynalyzer™
3. Set scope as follows:
Ch. 1 Vertical Scale
2 V / Division
Ch. 2 Vertical Scale
100 mV / Division
Horizontal Scale
50 mSec / Division
Trigger
Channel 1
Polarity
Positive
Mode
Normal
4. Turn the generator ON
5. Set up the generator as follows:
Mode
2 point
Focal Spot
Large
kV
84 kV
mAs
114 mAs
6. Make an exposure and verify that the kV and mA waveforms for the large focal
spot are correct. The kV and mA waveforms should rise together and stabilize
without any noticeable overshoots or undershoots.
7. Repeat the above exercise for the small focal spot. Set up the generator as
follows:
Mode
2 point
