Procedure

▪ Select large focus only.
NOTE
▪ Run reconditioning procedure for an adapted tube. Refer to the following table, left column "Tube adapted".
or
▪ Run conditioning procedure for a new or non–adapted tube. Refer to the following table right column "Tube
not adapted".
▪ It is recommended that the high voltage be monitored during conditioning.
Connect the scope:
Channel1:
Trigger external:
Time base:
▪ In case of problems like tube arcing see the following flowchart EXPOSURE SEQUENCE as an example.
The flowchart applies to the applicable kV range only, e. g.:
109kV is the max. kV value for normal application, set the next higher kV step = 117kV.
NOTE
Conv test Optimus
The generator must be in the READY state.
kV AV HT at EZ130 X3 (1V/div), scale: 20kV/V
CTRL_X_C/ at backpanel EZ X74, negative slope
2ms/div
Refer to flowchart EXPOSURE SEQUENCE.
If the tube arcs at a certain kV value, switch another three exposures with same pa‐
rameters and 10s pause between subsequent exposures. In case of success (no
arcing anymore) continue with next kV step of the following table.
If the last exposure still arcs go one kV step back and follow the normal procedure. If
this routine has been performed three times without improvement: ==> Replace the
tube!
