1 INTRODUCTION
PR VASET 2P is n electro-pneum tic le k tester dedic ted to perform pressure dec y le k
tests: It m kes it possible to bench test sm ll nd medium-size products, both stiff nd
flexible.
PR VASET 2P fe tures very comp ct dimensions, simple use nd high perform nces.
The pressure re ding offers 0.1 mb r resolution on the model 2P2B00 up to 2 b r full sc le
r nge nd model the model 2P6B00 up to 6 b r full sc le r nge.
The simple nd effective pneum tic circuit gu r ntees the reli bility shown on site by the
previous PR VASET models.
The c se is m de of unp inted st inless steel th t is suit ble for ny environment, especi lly
the white rooms of the biomedic l sector.
Beyond the le k test, PR VASET 2P llows to lso c rry out multiple obstruction test fter
the relev nt en bling.
PR VASET 2P h s 16 progr mm ble test p r meter t bles: e ch t ble includes the
p r meters djusting test cycle nd it is therefore possible to pre-set different test
conditions for different products.
PR VASET 2P h s six select ble units of me surement rel ting to the pressure.
PR VASET 2P h s five select ble l ngu ges for displ y mess ges.
PR VASET 2P h s n ided procedure m king it possible to c libr te the pressure sensor.
This vers tility, together with high ccur cy nd reli bility level nd n user friendly control,
m kes it possible to use the le k tester both in m nuf cturing dep rtments nd Qu lity
M n gement l bor tories.

sensitivity.
The tests should be performed always with the same type of connection
to have repetitive test results.
Check often the integrity of the connection between the instrument and
the tested products.
Do not tighten the tube stopping nut more than necessary (if you use a
tool, pay special attention).
NOTE: For the use of keys, see paragraph 6.1.

3 PNEUMATIC DIAGRAM
PR VASET 2P - Pneum tic di gr m
PICTURE 3
The pneum tic di gr m of the device is simple, but effective nd s fe.
It is m de up of:
•A pressure reducer (see point 6, p r. 2.2)
•Two 3/2-w y N.C. solenoid v lves: Both v lves gu r ntee tight se l nd c n be e sily
inspected for m inten nce nd cle ning purposes.
•A pressure tr nsducer: It me sures the testing pressure.
Both v lves 1 nd 2 re opened ( ctiv ted) only during the filling nd re closed
(de ctiv ted) during the settling nd the pressure dec y me surement.
In this w y, the piece being tested is connected to the pressure reducer (inlet ir) only during
the filling, while - during the settling nd the me surement - the piece being tested is
completely isol ted from the inlet ir, bec use the closed v lve 2 is ctu lly connected to
the disch rge outlet.
A possible blow-by or f ilure of v lve 2 during the test c n therefore only c use pressure
loss in the piece being tested nd not pressure incre se: The possibility th t n error of the
pneum tic circuit c n hide pressure le k of piece to be rejected is therefore excluded.

4 TESTING CYCLE
! CAUTION: This tester uses compressed air.
The oper tor must be protected g inst possible d m ge c used by
the ccident l det chment of p rts under pressure of the product to be
tested.
The tested product must conform with the binding requirements (ex.
directive "Simple pressure t nks").
4.1 Leak test cyc e with three phases
4.1.1 Operating princip e
% WARNING: The operator must carry out the test after ensuring that the supply
pressure adjustment is optimal (see point 6, par. 2.2).
The inlet pressure in particular must be maintained constant to allow a
good adjustment of the test rated pressure.
Before starting the testing cycle, it is necessary to set the operative
parameters of the "TEST TABLES" menu (see par. 6.3) and of the
"C NFIGURATI N AND PTI NS" menu (see par. 6.4).
The test cycle st rts fter receiving START comm nd.

rev. 14/02/2013 p ge 13
The three-ph ses test cycle is b sed on 5 progr mm ble p r meters.
T1 Fi ing time
Time T1 is st rted fter the START comm nd: It is the filling ph se. Air comes out from
the outlet connection on the front p nel (see p r. 2.1 point 5) to fill the piece being
tested t the test pressure Pr.
If the filling of the piece to be tested is provided outside the equipment, the time T1
c n be set t 0 (zero): t the START comm nd the equipment skips the filling ph se
nd, without opening the v lves, the test directly st rts from time T2.
By selecting the option Pr/T1 in the configur tion p r meters for the type of test with
three ph ses, the filling ph se is utom tic lly interrupted when the test pressure Pr is
re ched, without w iting for the end of time T1.
T2 Sett ing time
It is necess ry to w it until the el stic p rts in the tested piece re settled.
At the end of T2, if the pressure inside the tested piece is within the set percent ge
limits %Pr m x nd %Pr min, the pressure v lue is stored s reference point for
checking the Dp le k limit in time T3.
T3 Measuring time
The pressure dec y inside the tested piece is me sured.
At the end of time T3, the tester stores the test result nd displ ys the pressure dec y
th t w s me sured t the test end.
Pr Test rated pressure
It is the pressure v lue t which (with progr mmed percent ge toler nce %Pr m x
nd %Pr min) the le k test is c rried out.
The percent ge toler nce limits %Pr m x nd %Pr min of the test r ted pressure Pr re
progr mmed in the “configur tion nd options” menu.
Dp Pressure De ta
It is the m ximum limit of pressure dec y or pressure incre se which is ccepted
during the T3 time.
A pressure dec y is indic ted s neg tive v lue, with minus sign, pressure
incre se is indic ted s positive v lue, without sign.

4.1.2 Testing cyc e procedure
The tester ccepts test st rting comm nds t ny moment nd during the visu lis tion of
ny menu p ge, p rt from those rel ting to the pressure sensor c libr tion.
The test t ble used when testing is directly displ yed when st rting or fter "reset" of the

The two-ph ses le k test is simil r to the three-ph ses test: The only difference is th t in the
two-ph ses test, time T1 includes both the filling nd the settling ph se nd it is not possible
to set it t 0 (zero)
Time T2 is the me suring ph se of the pressure dec y.

This p ge is displ yed if, t the end of the "Filling" or "Settling"
time, the line pressure is not within the set %Pr m x nd %Pr
min limits or if the test h s been interrupted by n l rm.
The word "F iled" is displ yed if the pressure is lower th n the

4.6 Obstruction test
En ble the obstruction test inside the "Configur tion nd options" menu (see p r. 6.4).
The obstruction test function m kes it possible for the oper tor to check, during the settling
ph se, whether second ry p rts of the piece being tested re obstructed.
After START comm nd, t the end of the filling ph se, (th t is to s y during the settling
ph se), the oper tor c n open the closing plug of second ry p rt of the tested line nd
check the sudden pressure dec y th t t kes pl ce if the line is not obstructed: After re-
closing the plug, the le k test rest rts utom tic lly from the filling ph se.
The norm l procedure to c rry out the obstruction test is the following one:
1. Prep re the piece to be tested;
2. After START comm nd, the test st rts with the filling ph se, followed by the settling one;
3. Before the end of the settling ph se, open the plug th t closes the p rt th t you wish to
test;
4. If the p rt is not obstructed, sudden pressure dec y t kes pl ce nd is sign lled by the
sound of the buzzer for 1 second. The test rest rts from the filling ph se (st rt of time T1);
5. Re-close the plug on the tested p rt;
6. At the end of the filling ph se, the obstruction test c n be repe ted on nother
devi tion or the test c n go on like norm l le k test.
If during the obstruction test with opened plug the pressure dec y is not sudden, this dec y
c n be considered like settling nd does not c use ny sign lling: the test is c rried out
like norm l le k test.
NOTE: The obstruction test can be only applied with higher test pressure
of approx. 200 mbar.
