The X-ray tube needs to be warmed-up daily in order to extend the life of the tube
and prevent tube arcs (Especially when the X-ray tube was not used for a long
period). The seasoning procedure shall be done upon turning on the generator for
the first time.
Follow X-ray tube manufacturer´s recommended seasoning procedure.
If X-ray tube manufacturer´s seasoning is not available, then use the following
procedure:
Set PROVARIO HF Generator: Large focal spot, 200mA, 40mAs
Take 8 exposures starting at 50 kV and increment the kV steps of 10 kV up to 120 kV
(Exposure every 30 seconds, otherwise tube may arc).
See User Manual PROVARIO HF and CONAXX 2 User Manual chapter 5.3.
Detailed information please find in the enclosed User Manual of the X-ray tube.

Function of the PRS 500 F
4.10.1
Switching On/Off the PRS 500 F

every system component with power.
On the Generator and the control panel will run a self-test when switching them on. After the self-test
was successful the parameters will be displayed which can be saved under Organ-number #0.
When an Error gets displayed please see the manual generator.

Dosimetric Calibration (only for PROVARIO HF)
The Generator is running a self –test, at switching on and changing the tube in a two tube operation,
on the chosen area dose measuring chamber.
On this test every Vacutec area dose measuring chamber emits a determinated
number of test pulses, which are getting detected by the Generator, the Generator compares it with a
deposited test value. At a dev/- 2% the error E018 „DAP-System“ gets displayed on the control
panel which indicates a decalibrated measuring chamber.
The test value of the area dose measuring chamber, which can be found on the test protocol, has to be
applied to the parameter 846 of the Generator or via the Service program into the field “DAP test count
value x (120-300)” (1).
The current measured test value is displayed in the field “DAP measured value x”(2) after switching on
the Generator. For this the function “read from gen”(3) has to be executed. Modest differences in the
measures test value can be caused by air pressure fluctuations or wrong installed measure chambers.
