Introduction
ThankyouforselectingtheExtechCG206CoatingThicknessTester.TheCG206isaportable
meterdesignedfornon‐invasivecoatingthicknessmeasurementswithautomaticrecognitionof
thesubstratematerialundertest.
Themeterusestwomeasurementmethods:magneticinduction(forferrousmetalsubstrates)
andeddycurrent(fornon‐ferrousmetalsubstrates).
TheCG206metercanconnecttoaPCviaUSBandtransmitrecordeddataforfurtheranalysisand
forgeneratingreportdocumentation.
Properuseandcareofthismeterwillprovidemanyyearsofreliableservice.
Features
MeasuredCoatings:Non‐magneticcoatings(e.g.paint,zinc)onsteel;InsulatedCoatings(e.g.
paint,anodizedcoatings)onnon‐ferrousmetals
Intuitivemenu‐basedprogramming
Memorystorageofupto1500readingsin30groups(50readingspergroup)
Deletesinglereadingsorallgroupseasily
AutoPowerOFFwithdisablefeature
DatatransfertoPCviaUSB
UserZeroCalibrationability
Applications
Corrosionprotection
PaintShopsandElectroplaters
Chemical,Automobile,Shipbuilding,andAircraftindustries
Laboratory,Workshop,andFielduse

ProbeDescription
TheCG206probeisspringmountedinthesensorsleeve.Thisensuressafeandstablepositioning
oftheprobeandensuresconstantcontactpressure.
AV‐grooveinthesleeveoftheprobefacilitatesreliablereadingsonsmallcylindricalparts.The
hemisphericaltipoftheprobeismadeofhardanddurablematerial.

Measuringmetalliccoatings
Thismetercanmeasurenon‐magneticmetalcoatings(Zinc)onamagnetic(ferrous)substance
base,andnon‐metalcoatingsonametalbase(ferrousornon‐ferrous).

Operation
MeterPower

Installtwo‘AAA’1.5Vbatteriesintotherearbatterycompartment.Pressthepowerbutton
toswitchthemeterON.ThedisplaywillswitchON.IfthedisplaydoesnotswitchON,installor
replacethebatteries.Whenpoweringup,pleasekeepthemeteratleast10cm(4”)frommetal
objects.Replacethebatterieswhenthebatterystatusiconappearslow,themeterwillgive
inaccuratereadingsifthebatteryvoltagefallsverylow.
Measurements

BeforeeachmeasurementsessionpleaseperformaZeroCalibrationasdescribedlaterinthis
UserGuide.

Practicewiththefilmandzeroreferencemetalsubstratestolearnhowthemeteroperates
beforemovingtoaprofessionalapplication.Theheaviermetalsubstrateistheferrous
(magnetic)zerosubstrate(Fe)andthelightermetalsubstrate(Al)isthenon‐ferrous(non‐
magnetic)zerosubstrate.InAutomode,themeterautomaticallysensesferrousandnon‐ferrous
substrates.

1. Placeareferencefilm(250µm,forexample)ontheferroussubstrate(FE).
2. Powerthemeteronbypressingthepowerbutton.
3. Placethespring‐loadedmetersensoragainstthereferencefilm.
4. Themeterwillemitanaudibletoneindicatingthatthemeasurementhasbeentaken.
5. TheLCDwillshowthereadingatthecenterofthedisplayarea.
6. ForatypicaldisplayseetheDisplaydescriptiondiagram.

AutomaticPowerOFF
Inordertoconservebatterylife,themeterwillautomaticallyturnoffafterapproximately3
minutes.Todefeatthisfeature,usetheprogrammingmenudetailedinthenextsection(menu

ZEROCalibration

ThecustomershouldperformaZeroCalibrationbeforeanymeasurementsaretaken.
PreparingforZEROCalibration
1. Cleantheprobetipandthesubstrate(grease,oil,metalscraps.
Theslightestimpuritywillaffectmeasurementandwilldistortreadings.
2. SwitchthemeterONata10cm(4”)minimumdistancefromanymetal.
3. Setthemetertothecorrectsubstratetype,FEorNFE.
4. Themeterisnowreadyforcalibration.
ZeroCalibration
ZEROCalibrationfromtheProgrammingMode
1. Fromthenormalmeasurementmode,presstheLEFTbutton(SEL)toaccessthemenu.
2. UsetheUP/DOWNbuttontoscrolltoCALIBRATIONmode.
3. PressLEFT(SELECT)toopentheCALIBRATIONparameter.
4. Scrollto‘CALZEROOFFE’or‘CALZEROOFNFE’

7. PresstheLEFTbutton(OK)toacceptthecalibrationvalueorpresstheRIGHTbutton
(CANCEL)toabortthecalibration.
8. Ifthemeterdidnotread0.0youcantryagainor“Set”theZeroreferencebypressing
andholdingtheZERObuttonuntilthemeterbeeps.
9. WhentheZerocalibrationiscomplete,themeterisreadytomakemeasurements.

NotethattheusercandeleteZEROCalibrationdatabyselecting‘DelZEROofFE’or‘Del
ZEROofNFE’fromtheCALIBRATIONmodeintheProgrammingmenu.

ZEROCalibration–RelativeMode
1. Thismodecanbeusedtosetazeropointonreferencesubstrateoronaknown
thicknessofmaterial.
Forarelativemeasurement,anythicknessgreaterorlesserwillbereferencedtothisset
value.
2. PressthesensoragainsttheFEorNFEzeroreferencesubstrateoronaknownthickness
