Possible reasons and advice
The deviation can depend on the
adaptation.
•
Measure the kV curve at
measuring point "HTPEAK" (see
page 140**). Compare the
measured curve with the reference
curve (see page 141**).
For a large deviation:
•
Check the filament value (see
section "P07 - Read-out filament
values from battery backed RAM")
and compare it with the values in
the delivery protocol.
•
If the difference is large a new
adaptation is needed (see section
"P10 - Fast adaptation")
•
See also section "Error diagnosis
HT and single tank".
•
Check the connection K9 between
D1 and H1 (single tank) and the
connection between D1 and D13
(K8) (see page 140**)
