keys all segments of the numerical
display are scanned.
c
By pressing the X-ray pushbutton
the “rAY” message is
displayed.
d
By pressing each button on the panel, the corresponding lamp
turned “ON”; a second pressure would turn it “OFF”.
e
At the last button pressed the system automatically exit this
function.
WARNING: Do not press the X-ray pushbutton as last
button twice; the second time the timer becomes active
and radiation is emitted.
5. MEASUREMENTS
All measurements to be done with the equipment supplied at nominal line
voltage with specified line resistance (see section 2.2 at page
tolerances on the measured values have to take into account the precision of
the each measurement instrument. Measurements have to be done by
trained personnel only to avoid the risk of electrical shock.
5.1
Line Voltage
The Line voltage can be measured using a Volt Meter for Alternate Current
within the proper range. A service function can be activated on the AutoSet
timer to display the current line voltage (see section 4.8 of this Manual).
5.2
Anode Voltage – KVp
The kVp level is the actual peak value of the Anode voltage which
stabilizes once the preheating time of the filament has elapsed (in about
0.2 s) and the high voltage transformer is actually loaded. The kVp level
can be measured with a non-invasive kVp meter placed in front of the BLD
following the instructions in the user manual of the instrument.
measure can be done with an exposure time of 500 ms or more having
introduced a delay of the reading instrument of about 300 ms to allow the
voltage level to stabilize after the pre-heating time has elapsed.
5.3
Anode Current – mA
WARNING. To prevent high voltage shock make sure the system
is disconnected from the power supply when connections to the
measurement points are performed. Electric discharge might
