P13 - Inverter test

Only available if the FW version is lower than or the same as 1.5 or 1.5E.
Wiring diagram X037E, page 140)
NOTE
The main purpose of the test is to check the gate pulses on the transistors in the main
inverter. Each time the exposure button is pressed, the program runs the main inverter for
10 ms. During the test, there is no filament heating or rotation activated and the voltage in
the capacitor bank is <10 V. The display shows the following:
The test is stopped with the lamp button.

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 for
MOBILETT Plus/Plus M and 24 or 47 steps for MOBILETT Plus E. The number of steps
corresponds to Siemens point scale with integer points or half integer. The factory setting
is 25 steps for MOBILETT Plus/Plus M and 24 steps for MOBILETT Plus E . 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:
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:
Siemens-Elema AB
Solna, Sweden
When the test is started, it will take approximately 5 minutes to
reduce the voltage in the capacitor bank. The ready light indicator
indicates when the unit is ready for test.
