Thesellerisobligatedtoprovideawarrantyofveyearsforthedeliv-
eredgoodsregardingmaterialandmanufacturing.Thewarrantyperiod
isconsidered tostart on thedelivery dateof theproduct.If a defect
in raw materials or a produconawisfound, theseller is obligated,
whentheproductissenttothesellerwithoutdelayorbeforeexpira-
onofthewarranty,toamendthemistakeathis/herdiscreoneither
by repairing the defecve product or by delivering free of charge to
thebuyeranewawlessproductandsendingittothebuyer.Delivery
costsfor therepairunderwarrantywillbepaidbythebuyer and the
return costs by the seller. The warranty does not comprise damages
causedbyaccident,lightning,oodorothernaturalphenomenon,nor-
malwearandtear,improperorcarelesshandling,abnormaluse,over-
loading,improperstorage,incorrectcareorreconstrucon,orchanges
andinstallaonworknotdonebytheseller.Theseleconofmaterials
fordevicespronetocorrosionisthebuyer’sresponsibility,unlessother-
wiseislegallyagreedupon.Shouldthemanufactureralterthestructure
ofthedevice, thesellerisnotobligatedtomakecomparablechanges
todevicesalreadypurchased.Appealingforwarrantyrequiresthatthe
buyerhascorrectlyfullledhis/herduesarisenfromthedeliveryand
stated in the contract. The seller will give a new warranty for goods
thathavebeenreplacedorrepairedwithinthewarranty,howeveronly
totheexpiraonoftheoriginalproduct’swarrantyme.Thewarranty
includestherepairofadefecvepartordevice,orifneeded,anewpart
ordevice,butnotinstallaonorexchangecosts.Undernocircumstance
isthesellerliablefordamagescompensaonforindirectdamage.
2)ManualPushbuonzeropointcalibraon
NOTE:Supplyvoltagemustbeconnectedatleastonehourpriortozero
pointadjustment.
a)Disconnectbothpressuretubesfromthepressureportslabeled+
and–.
b)PushdownthezerobuonunltheLEDlight(red)turnsonandthe
displayreads“zeroing”(displayopononly).(seeFigure4)
c)Thezeroingofthedevicewillproceedautomacallyin4seconds.
Zeroingledlightsonlyforamoment.Zeroiningiscompletewhen
thedisplayreads0(displayopononly).
d)ReinstallthepressuretubesensuringthattheHighpressuretube
isconnectedtotheportlabeled+,andtheLowpressuretubeis
connectedtotheportlabeled−.
STEP 8: ZEROING THE DEVICE
WARRANTY POLICY
RECYCLING/DISPOSAL
The parts le over from installaon should be
recycled according to your local instrucons.
Decommissioned devices should be taken to a
recyclingsitethatspecializesinelectronicwaste.
ZEROING THE DEVICE CONTINUED
1)Autozerocalibraon
Autozero calibraon (-AZ) is an autozero funcon in the form of an
automaczeroingcircuitbuiltintothePCBboard.Theautozerocali-
braon electronically adjusts the transmier zero at predetermined
me intervals(every10minutes).Thefuncon eliminatesalloutput
signaldriduetothermal,electronicormechanicaleects,aswellas
theneedfortechnicianstoremovehighandlowpressuretubeswhen
performing inial or periodic transmier zero point calibraon. The
autozeroadjustmenttakes4secondsaerwhichthedevicereturnsto
itsnormalmeasuringmode.Duringthe4secondadjustmentperiod,
theoutputanddisplayvalueswillfreezetothelatestmeasuredvalue.
Transmiersequippedwiththeautozerocalibraonarevirtuallymain-
tenancefreeandmanualzeroingisnotrequired.
Theresponsemeaectshowfastthetransmierreactstochangesin
thesystem.Theresponsemeisthemethedevicetakestoreach63%
ofthemeasuredvalue.Tosmoothoutunstablepressureuctuaonsin
airowapplicaons,selectalongerresponseme.
Example:
Selectedresponseme:8.0seconds
Result: Output signal achieves a new value in 40 seconds (Response
me*5)
Tochangeresponseme,installorremovejumperonJ4.
(seeFigure3)
1)InstalljumperonJ4for8.0secondresponseme.
2)RemovejumperfromJ4for0.4secondresponseme.
STEP 6: SELECTING THE RESPONSE TIME
STEP 7: Using 2-10 V output
Insomeapplicaonsitiscricaltoknowimmidiatelyifthewireis
brokenorthedeviceisdamaged.Inthesecases,a2–10voltageoutput
isrecommended.
1)InstalljumperonJ6for2–10voltageoutput
2)RemovejumperfromJ6for0–10voltageoutput
NOTE!WhenusingcurrentoutputJ6circuitmustbeopen!
NOTE! Always zero the device before use.
Tozerothedevicetwooponsareavailable:
1)Autozerocalibraon(manualzeroingnotrequired)
2)ManualPushbuonzeropointcalibraon
a) Disconnect both pressure tubes from the pressure ports labeled +
and –.
b) Push down the zero buon (joysck) unl the LED light (red)
turns on and the display reads “zeroing” (display opon only). (see
Figure 6)
c) The zeroing of the device will proceed automacally. Zeroing is
complete when the LED turns off, and the display reads 0 (display
opon only).
d) Reinstall the pressure tubes, ensuring the High pressure tube is
connected to the port labeled +, and the Low pressure tube is
connected to the port labeled −.
Press down buon
LED turns ON
Display reads “Zeroing”
