STEP 4: SELECTING THE MEASUREMENT UNIT
1)Selectthedesiredmeasurementunit.(seestep4)
2)Selectthedesiredmeasurementrange.(seestep5)
3)Selectthedesiredresponseme.(seestep6)
4)Zerothedevice.(seestep7)
5)Connectthepressuretubes.Connectposivepressureto
portlabeled“+”andnegavepressuretoport“-”.
6)Closethelid.Thedeviceisnowreadytobeused.

2)InstalljumpersonJ1,J2andJ3asrequired.
a.Usingtherangenumberfrom1cabove,ndthecorresponding
rangenumberinChart2.
b.InstalljumpersonJ1,J2andJ3ondevice,asshownundertherange
numberinChart2.(Greycolourindicatesthatajumperisinstalled.
Referencegure3forjumperinstallaon.)
1)Tochangethemeasurementunitappearingonthedisplay,installa
jumpertobothpinsofJ5(seeFigure3).
2)Pushdownthezerobuonandthemeasurementunitopons(Pa,
kPa,mbar,inchWC,mmWC,psi)willcycleonthedisplay.
3)Toselectaunitopontodisplay,removethejumperfromJ5
whilethemeasurementunitisvisibleonthedisplay.

Example:
Selectedresponseme:8.0seconds
Result: Output signal achieves a new value in 20 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0.8secondresponseme.
STEP 6: SELECTING THE RESPONSE TIME
STEP 5: SELECTING THE MEASUREMENT RANGE
1)Determinetherangenumber
a.FindthemodelinChart1.
b.Findthemeasurmentunit(selectedinstep4).
c.Findtherequiredmeasurementrangeonthesamelineasthe
measurementunit(babove)anddeterminetherangenumberinthe
header.
