P11 - Backup battery test

(Wiring diagram, page 110)
After activating the program, it will display the battery voltage:
kV
bAt 3.2 = 3.2 V
When the battery voltage is <2.8 V, the battery needs to be replaced. Refer to the section
"Replacement of backup battery". After 5 seconds, the program will be aborted. If the bat-
tery voltage is too low, there will be a message displayed with a message beep:
kV
P11 CAL 31
If the battery voltage is OK, the display will show:
kV
P 11 PASS = Battery OK

P14 - Number of kV steps and upper kV limit

The program consists of two parts. The number of kV steps is selected in the first part and
a kV limit is selected in the second part. When the first part is finished, the second starts
automatically.
The first part, selecting the number of steps:
In this program, it is possible to choose between a fixed number of 25 or 49 steps. The
number of steps corresponds to Siemens point scale with integer points or half integer.
The factory setting is 25 steps. To change or check the valid setting, activate the program
with the lamp button.
The display shows the selected number of kV steps, change with kV + or - buttons.
Example:
kV mAs
25 StEPS = 25 kV steps selected
Pressing the lamp button stores the currently displayed values and activates the second
part.
The second part of P14 is the selection of the upper kV limit:
The display shows the selected highest available kV (min. 40 and max. 133 kV). This can
be changed with the kV + or - buttons.
Example:
kV
133 SEt = kV values up to 133 kV is allowed.
