STEPS

1. ConnectOscilloscopeCH1 betweenTP16 (kVp)and Gnd to TP13 on

PortableControlBoard.

ConnectOscilloscopeCH2 betweenTP'l5 (mA)and Gnd to TP14 on

PortableControlBoard.

ConfigureCH1 in 2Vldiv and CH2 in O.SV/div.Time base in 50 ms/div;

triggerin Normalmodeby positiveedge of CH1.

4. mA and kVp relation,measuredin the Oscilloscope,

is as follows:
Kvp relation= 1 V/10kV mA relation=1V/10mA

During Calibration procedure Collimator blades must be fully

CAUTION closed and the Collimator kept inside the leaded box to avoid
risks of radiation.

3.2 CALIBRATION (kvp AND mA GAIN)

OF PARAMETERS

1. To enter calibration press "CollimatorLamp" push-button. Keep it

pressedand press "mAslncremenf"push-button.Releasefirst only the
"mAs lncrement" push-button (two beeps will sound). Release
"CollimatorLamp" push-button( the kVp displaywill show 40, 80 100 or
110). Select 80 with the "kVp" push-button; mA will also be shown on
mAs display. Press mAs to selectthe lowestmA stationin Large Focal
Spot. Select"LargeFocalSpot".

2. Make an exposure.Measure kVp and mA signal values with the

Oscilloscope . Verifythat both signalsare flat and noiseless.lf the mA
valueobtainedis not the selected,incrementor decrementthe filament
current value (shown on the kVp display) pressing "Collimator Lamp"
push-button.Pressand hold "CollimatorLamp" push-button,then press
"kVp lncrement" or "kVp Decrement".

3. Makean exposureagainto verifythat the mA valuein the Oscilloscope

is the one selected; if it is not, repeatthe procedureto incrementor
decrementthe value. Whenthe correctmA valueis reached,validatethe
value pressing"Collimator Lamp" and "mAsDecrement",or deactivate
it pressing "mAs Decrement" and "CollimatorLamp".

4. To validateany mA heatingvalue, press and hold "CollimatorLamp",

then press "mAs Decrement"push-button(one beep will sound and the

3.2.1 CALIBRATIONOF kVp GAIN

1. To exit Calibrationmode press "CollimatorLamp" push-button;keep it

pressed and press "mAs lncremenf" push-button.Releasefirst 'mAs

3. To enter calibrationof kVp Gain press "CollimatorLamp", and the mAs

display will show the kVp value (80.0) that may be changed pressing
"mAs lncrement" or "mAs Decrement".

4. Placea non-invasivekVp meter alignedto the X-ray bean to a focal

distance(100 cm SID).Openthe lightfield to centerit with the meter.
Makean exposureand readkVp in meter.Takenoteof the value.Enter

push-button(displaykVp will show gain value during 2 seconds).
kVp Gain correspondenceis
G=1 corresponds to 200

That meansthat the kVo realvalue measuredin Oscilloscope

is:

kVp(real) = Number of steos (kVp validated) x 1(G) x kVp (measured

3.2.2 CALIBRATTON HEATING(SMALLAND LARGE FOCAL SPOTS)

OF FTLAMENTS

Note W lf a filament current value is calibrated and only one mA or kVp

station is changed, calibration data of previous station remains
(this is useful in order to not to have to change the valuein all
stations).Take special care when proceeding to recalibrate or to
verify any station since a value already calibrated remains
although the mA or kVp station is changed.

1. To enter Calibrationpress "CollimatorLamp" push-buttonand while

holding it pressed, press "mAs lncrement"push-button.Release first
"mAs lncrement" push-button (two beeps will sound). Release
"CollimatorLamp"push-button:kVp displaywill show 40, 80, 110or 100;
press"kVp"to select80; mAs displaywill also show mA. Press 'mAs"
push-buttonsto selectthe lowestmA. Any "FocalSpot"will blink. Select
"Large FocalSpot".

2. Make an exposure.Measurein Oscilloscope signalvaluesof kVp and

mA. Verifythat both signalsare flat and noiseless.lf mA obtainedis not

(shown on the kVp display) with "CollimatorLamp" push-button. While
holding it pressed, press "kVp lncrement" or "kVp Decrement"
push-button.Make the exposureagainto verify that the mA value in
Oscilloscope is the selected. lf it is not, repeat the procedure
incrementrngor decrementingthe value. lf the correct mA value is
obtained.validateit as follows:

3. To validate any mA heating value press and hold "CollimatorLamp"

push-button,thenpress."mAsDecrement" push-button(one beep will

3. To set the heatingvalueof the mA that correspondsto 20mA and 80 kVp

(previously calibrated) press "kVp lncrement" or "kVp Decrement"
push-button.Makean exposureand verifythatthe mA signalis flat and

SECTION4 TROUBLESHOOTING

The generatorcontainsmanyself-diagnostic routineswhichgreatlyfacilitates

troubleshooting.
The self-diagnostic
functionsrequirecorrectfunctioningof the
microprocessor.

As a general rule, the first step in any troubleshootingprocedureis to verify

correctpower supplyvoltages.

Note E Whenever the Unit is turned off, wait S minutes before turning it
oN.

Note E Whenever a Portable Control Board or a Control Driver Board or

a High Voltage Tank is replaced, it is necessary to perform the
calibration procedure. See Section 3 Calibration procedure.

4.1 ADDITIONAL FILTER INSTALLATION

The Unit allows installationof additional compensationfilters (997o purity

AluminiumFilters)at emittingfocal spot. Follow steps describedbelow for
installation:

1. Turnthe PortableUnitOFF.

2. Disassemble
cover.Do not uninstall/remove
metrictape.

3. Loosecollimatorscrewsandleaveit open.Do notdisconnectany cable.

4. Remove two opposite nuts from HV Transformer at Tube window

housing.

5. Installfilterand fix it withremovednuts.

6. Re-lnstallcollimatorand check correctAlignmentof collimatorLight

Area and X-Ray ExpositionArea. lf necessary,readjustcollimator(see
CollimatorManual).

7. Assemblecover.

SYMPTOM

appliesconstantfilamentcurrentto the tube.This currentis proportionalto the
current already calibratedfor that mA station at the kVp selected for that
Exposure(filamentnumbers).Attheendof thatramp,the microcontroller reads
the mA, and if they are foundto be 15% belowor over what has been selected,
generatesError 12.

POSSIBLE
CAUSE
Calibrationdata for kVp and for mA that generateE12 are not correct.

Thereis a problemon the readingof the mA.

Insufficientheating before the Exposure.The filament has not reached its

correcttemperatureand the mA at the startingof the exposureis low. lt may
occurat high mA becausethe boosteris smallersincethe X-raytube current

suggested intervals,are the manufacturer'srecommendationfor the most
effectivePeriodicMaintenanceschedulefor this generator.

Service tasks here described must be performed exclusively by service

personnelspecifically
trainedon medicalX-ray generators.

The first periodicmaintenanceserviceshouldbe performedsix (6) monthsafter

installationand the subsequentserviceseverytwelve(12)months.

NEVERATTEMPT TO CLEAN INTERNALLY THE UNIT. THE

UNIT MUST BE ALWAYS KEPT SHUT UNLESS A SPECIFIC
RENEWAL PABT PROCEDURE IS TO BE UNDERTAKEN BY
HIGHLY QUALIFIED MAINTENANCEPERSONNEL.

5.3 CABLE CHECKS

Check that all electricalconnectionsare firm and secure and that all cable
clampsand strainreliefsare in place. Alsocheckthat connectorsdo not have
exposedwiresand checkcablesheathsfor wear and fraying.

Checkthat all cables are correctlyrouted.

5.4 CONTROLPANEL

Verify that the handswitchcable and its connectionto the unit are in good
condition.

Check correct operationof the push-buttons,displays and indicatorsby

performingthe followingtest:

1. Turn the generatorON by pressingthe "PowerOn" push-buttonon the

ControlConsole.

2. Selecta radiographic
techniqueand observe:

. Techniqueparametersare displayedon the console.

. Change techniqueparametersand observethat changes are

correctlydisplayed.

. Select70 kVp and maximummAs.

. Press "Prep" and verify that the "Ready"indicatoris illuminated.
