5.5 X-ray generator
5.5.1 Inspecting the X-ray generator
The YSi-X uses an X-ray generator which has a limited service life. Use the self-test function to make periodic
checks for the service life.
1
On the Unit screen, press the [X-ray Information] button in the “Utility” group box.
The “X-ray Information” screen appears.
2
Perform self-test.
From the drop-down list in the “Operation" group box, select “Self-test” and press the [Execute] button.
The service life level will be calculated based on the total power-on time and irradiation time. Wait for a
while (about 90 seconds) until the calculation is complete.
During self-test, the message “X-RAY SELF TEST” appears at the right end of the status area.
