Generator Adjustment Check 2.1
1. Click on <Go> to activate “Multiple Exposure”.
¹The system is now in direct exposure mode.
2. Select 81 kV with the kV+ / kV- keys and 8 mAs with the mAs+ / mAs- keys
3. Connect oscilloscope channel 1 to D1.X46, ground at 0V for "mA ist".
¹Set the sensitivity to 2 V / Div. (1 V = 2.5 mA).
4. Connect oscilloscope channel 2 to D1.X48, ground at 0 V for "kV ist".
¹Set the sensitivity to 2 V / Div. (1 V = 20 kV)
¹Set the time to 5 ms / Div.
X5. Release an exposure with the hand switch and store the oscillogram.
6. Evaluate the oscillogram (Fig.1/p.9), tolerance for the mA curve:
¹The tube current must reach 13 mA ± 1.5 mA within 3 ms
7. Click on <Go> to stop the direct exposure mode.
8. If the tube current (Fig.1/p.9)exceeds the specified tolerances, the generator adjust-
ment and the mAs counter adjustment must be repeated.

Load counter 2.2
Store load counter data
1. Switch on the system and insert a CD in the CD-ROM drive.
2. Open the service application.
3. Click on <Reports> and <Configuration Online>.
¹A new report of the main system will be generated.
4. Click on <Exit> to close this window.

¹A window appears “Do you want to burn a newly created developer SaveLog
too?”.
6. Click on <Yes> , <Select All> and <Burn Files>.
¹All data will be burned on the CD, including the actual load counter data and the
event log.
NOTE Replacing the D1 board (main system) sets the “reset counter”
and the load units to “0”.
Load counter reset
1. Install the new tube and enter the new single tank serial number under <Main Sys-
tem>-<Configuration>-<Load Counter>.
2. Under “Adjustment” click on <Load Counter>.
3. Click on <Go> to reset the load counter.
¹A load counter reset is only possible after the new single tank serial number is
entered under <Main System>-<Configuration>-<Load Counter>.
4. Click on <Go> to end the reset of the load counter.
¹The main system reboots
¹A error message appears “Single Tank is not equal...”
NOTE After a load counter reset, the serial number of the new tube is not
shown under <Main System>-<Adjustment>-<Load Counter> until
a “Generator Adjustment” has been performed.
5. Under “Adjustment” click on <Generator Adjustment> and perform a “Generator Adjust-
ment”
6. After the “Generator Adjustment” check whether the “Load Counter” reset has been
carried out.
¹Check under <Main System>-<Adjustment>-<Load Counter> to see if the “single
tank serial number” has changed to the new tube serial number.
NOTE Send the burned CD together with the single tank and the tube
questionnaire back to the factory (as required by the terms of the
warranty).
