Stepone:SelectingtheTransducerandProbezero&calibration

Temp. Application
S102512520～590<60℃Usedinthemeasurementof
compositematerials
Plugintransducer;turnonthemainunitusingthe  Key.Thegaugedoes
autocalibrationofthetransducer,thuseliminatingtheneedforanon‐block
zero.Afterturningonthegauge,thescreenflashestheSeriesNo.and
softwareversion,andthen,itcomesintothemeasurementmodedirectly.
Ifusersturningontheunitwithoutthetransducer,screenwillremindto
"Plugintheprobe".Atthismoment,pleaseinsertatransducerintothe
socket,thegaugedirectlycomesintothemeasurementmodeafterAuto
calibration.
  
Notice:Pleaseusethestandardtransduceroffered.Otherwisetheunitdoes
notworknormallyanddisplaying“Error”.
Ifusersfeelthethicknessreadingisincorrectduringthemeasurement,
pleaseputtheprobeintheair,andpressforzerocalibrationatany
time.
Notice:ForAutocalibration,makesurethetransducerisnotcoupledtothe
testpiecewhenthegaugeisfirstturnedonandthereisnocouplantonthe
endofthetransducer.Thetransducershouldalsobeattheroom
temperature,cleanwithoutanynoticeablewear.
StepTwo:Treatmentofthemeasuredsurface
Whenthesurfacetobemeasuredistooroughorrustyheavily,please
performthetreatmentaccordingtothefollowingmethods:
1.Cleanthemeasuredsurfacebygrinding,polishingorfiling,etc.oruse
couplingagentwithhighviscosityforthat.
2.Usecouplingagentsontheworkpiecesurfacetobemeasured.
3.Takemultiplemeasurementsaroundthesametestingpoint.

‐9‐
StepThree:Settingvelocity
Soundvelocityplaysanimportantroleinmeasurement.Differentmaterialis
ofdifferentsoundvelocity.Whenthesoundvelocityisincorrect,itwillcause
wrongmeasuredresults.Thereare3waystosetthematerial'ssound
velocity,whichare:
1.Directlyselectpresetmaterialvelocity.Pleasereferto8.2.1.2onpage3.
2.Inputthenewvelocitywhichisnotpresetintothemenu.Pleasereferto
8.2.1.3onpage4.
3.Gettheaccuratesoundvelocityoftheworkpiecewhichthethicknessis
known.Pleasereferto8.2.1.4onpage4.
StepFour:Measurement
TheDC‐5000isnowreadytomeasure.Therearefourdifferent
measurementviewoptions,A‐ScanRF+,A‐ScanHALF+,B‐ScanandDIGITS,
eachwithaspecificpurpose.
A‐ScanRF+:Itshowsboththepositiveandthenegativepeaks.
A‐ScanHALF+:Itshowsthepositive.
B‐Scan:Itdisplaysatimebasedcrosssectionviewoftestmaterial.
DIGITS:Itisabasicdigitalthicknessgaugelookandfeel.Thecolorandlarger
digitsmakeitmucheasierfortheoperatortomonitorthethickness
readings.

Velocitymeasurement
Sometimesthesoundvelocityofamaterialisnotknown.Inthiscasea
samplewithaknownthicknesscanbeusedtodeterminethesound
velocity.Itwouldbeveryhandytocarryasetofmechanicalcaliperstouse
inconjunctionwiththeDC‐5000inthefield.
Thefollowingstepsoutlinehowtoenableandsetupthisfeature:
1)Physicallymeasureanexactsampleofthematerialoralocationdirectly
Onthematerialtobemeasuredusingasetofcalipersoradigital
micrometer.
2)Applyadropofcouplantonthetransducerandplacethetransducerin
steadycontactwiththesampleoractualtestmaterial.
3)Thedisplayshouldshowathicknessreading(probablyincorrect).
4)Havingachievedastablereading,removethetransducer.(Ifthe
Displayedthicknesschangesfromthevalueshownwhilethetransducer
Wascoupled,repeatstep3.)
5)PressthekeytoilluminateSET,Use     keysto
scrollthroughthesubmenuitemsuntilVelocityMeasurementis

6)Presstheor  keytomovethecursor,pressthe  or
keytoadjustthedisplayedvelocityupordown,untilthethicknessvalue
displayedmatchesthethicknessofthesamplepiece.Andnowthe
