13 RECONDITIONING OF THE TUBE(S)
▪ Place one oscilloscope probe at
EZ130 X3 AV_HT actual value high voltage (total kV, 20kV/V) and ground EZ130 X6.
Use large focus only!
▪ Run the reconditioning procedure (see next page) for the applicable kV range only.
If, for instance, 125kV is the max. kV value during normal application, perform reconditioning just up to the
next kV step = 130kV.
If the tube arcs at a certain kV value proceed as follows:
▪ Switch another three exposures with the same parameters and 10s pause between subsequent exposures.
▪ If the last exposure of a sequence does not arc, proceed with next kV step.
▪ If the last exposure still arcs, go one kV step back and start again with the normal procedure.
If this routine has been performed three times without improvement:==> replace the tube!

NOTE
If a tube arcs at a kV value that is not required for application, the max. kV (e.g.125kV)
value can be reduced with
