6.5 Control via a PC with “measure”
As an alternative with regard to the direct control of the unit
via the control panel, the control of the unit and the represen-
tation of the measurement values can also be realised with
the aid of a PC and the “measure” software (14414-61).
6.6 Automatic shutdown of high voltage in case of fail-
ure
In case of interfering signals in the mains supply, the high
voltage will automatically be cut off in means to protect the
device from defects (introduced with firmware V
2.1). This
can be discerned by the fact that the x-ray tube stops to
gleam.
Running measurements eventually will not stop during the
shutdown, so they probably have to be restarted.
After removing the source of interference, check the door
status button IV and lock the door, if necessary (LED has to
be green). Afterwards, the device can be put into operation
again by pressing the X-ray button V. Thus, the high voltage
is switched on again and the measurement can be repeated.
If the device is controlled via a PC, the USB connection has
to be unplugged and plugged in, anew.
7 CHECKLIST
According to this list the device should be checked at least
two times per year:
1. Check if the device shows any damage.
2. All glass panes must be undamaged.
3. Start the x-ray device according to chapter 6.1, 6.2 of this
operating instruction. Perform a functional test of the
status indications, e.g.:
Do all LEDs work porperly?
Is symbol „I“ enlighted in operating state 3 (Ta-
ble 3)?
4. Check all functionalities according to table 2 of this oper-
ating instruction:
In operating state 1 and 2 it is not possible to acti-
vate the x-radiation.
In operating state 3 the x-radiation is not active, the
door is locked.
Only in operating state 4 the x-radiation is active.
Does sign
appear on the screen (Fig. 11)?
If you activate the x-radiation with the following pa-
rameters: anode current 1
mA, anode voltage
35
kV, the x-ray tube should gleam brightly.
The device is only ready for use if the tests are performed in
the right way and successfully. Even if
only one
test fails the
device must not be used. Please contact the Phywe service
in this case. ([email protected]).
