1. Introduction

This unit isan intelligent handheldproduct, which adopts

ultrasonic measuring principle,and is controlledby micro

processor, providesquick and precisemeasurement of

thickness for mostof industrial material.This unit is widely

used in variousprecise measurement fordifferent hardware /

parts in industrialrealm; one ofits important application

is to monitorthe level ofthickness-decreasing during

operation of variousand pressure container. Diffusely

applied in manufacturefields, metal processing,and

commercial inspection.

6.1 Battery replacement

When low batteryicon is showed,please replace thebatteries.

A. Press toturn off.

B. Open thebattery door properly.

C. Replace thelow power batteriesby new batteries.

When the gaugeis not usefor long period,please take outthe

batteries.

6.2 Protection oftransducer

Because the wearface of transduceris propylene materialwhich

easy to bescratched. During takingmeasurement on rough

material, please usingthe transducer ingentle motion. The tem-

-perature of thehardware should notover 60 , otherwise itwill

cause damage onthe transducer.Adhering oil,dust on thewear

face will speedup aging oftransducer and leadto rupture. Clean

the lead-wire &transducer after use.

6.3 Cleaning thecabinet

Do not usesolvent/alcohol for cleaningwhich erode thecabinet

& LCD window, brush andsweep only witha moist cottoncloth.

6.4 Cleaning thesample block

Because of couplingagent should beput on thesample block

during calibration, afteruse the sampleblock should becleaned

for preventing rust.In higher temperatureenvironment, be sure

protect the blockform the dropletof water.If the gaugeis not use

for a longperiod, please applysome antirust onthe sample block.

6.5 Avoid shocking/impact. Do not store the unit in high humidity

environment.

5.6 Multilayer /composite material

It is impossibleto read outthe thickness ofthe uncoupled mult-

-ilayer for theultrasonic wave cannot go throughthe uncoupled

space. Further more,the sonic wavecannot travel inthe comp-

-osite material atan even speed,so ultrasonic reflectprinciple

cannot be appliedto measure themultilayer/composite material.

5.7 Influence fromthe oxidized surface

For some metals,such as aluminuma layer ofoxide being

generated on theirsurface. The oxidized layer combined with

the substrate tightly, but thesonic wave travel within 2 different

material which willlead to errorreading, the moreoxidized layer

the reading willbe more tolerant.Please calibrated theunit with

the sample blockthat pick upalong the hardwareto be measured,

and obtain thethick of sampleblock by usingmicrometer.

5.8 Abnormal reading

A seasonedoperator should becapable to distinguishthe

abnormal reading, practicallyresult from rusting,erosive recess

surface / incorrectcalibrate sample block/the inner flawof

material.

5.9 Choose andusing coupling agent

Coupling agent serves the high frequency ultrasonic wave tran-

-smitting between thetransducer to thehardware. Choose inco-

-rrect agent orwrong operation mancause error orpoor coupling

which lead tofailure of measuring.The coupling agent should

be used inproper way, typiccally, a singledroplet of agentis

sufficient.

It is importantto use proper coupling agent, low viscosity

agent(the provided agent/ machining oil)is suitable forsmooth

surface. For rough/ veritcal /aluminum surface, highviscosity

agent like glycerinand lubrication greaseis applicable.All kinds

of coupling agentis available inlocal market, youcan buy itform

local distributor aswell.

5. Precautions foraccuracy

5.1 For verythin material

Any ultrasonic thicknessgauge, when thethickness of themat-

-erial to bemeasured is lessthan the minimumlimit the fault

reading will occurs.Using sample blockcompare method to get

a minimum limitof this material.

5.2 For stained,rusting surface

The stained/rusting surfaceon the contraside will occurs the

ruleless wrong readings.Sometimes a smallstained spot is

hard to findout. Take care formeasurement while measuring the

known rusting spot/suspiciousarea. Or usingsound insulation

boardcelotex to locatesthe spot indifferent testing angles.

5.3 Identify different velocity with vary material

A faultreading would obtains,when measuring the hardware

with the velocitycalibrated by priormaterial. So acorrect

velocity should beadopted. The fault reading may also result

form the difference between the actual velocity with the calibr-

-ated value.

5.4 Abrasionfo the transducer

Because the transduceris made ofpropylene, long period use

will cause thesurface of transducerbecame more rough which

will decline thesensitivity lead tothe wrong reading. Please

polish the surfacewith sand paperor whetstone to assure the

smoothness and parallel.If the readingstill unsteady, the tran-

sducer should bereplaced with newone.

5.5 ZERO function

ZERO(calibration) is usedto calibrate theunit with thestandard

block on thepanel, do pressthis key forcalibration with other

materials or willthe wrong measuringwill take place.

3.1. Before measurement

(1). Connectthe transducer withthe unit, press to turn on,

LCD with fullscreen display withback light for0.5 second, then

LCD display thelast applied soundvelocity, now the unit is ready

for use.

(2). Soun velocityselection

4.7 Influence ofthe material temperature

The size &sound velocity ofmaterial will change with the tem-

-perature, when theprecision is critical,please make measur-

-ement in 2samples of thematerial under thesame temperat-

-ure to determinethe proper readingresulting from the temp-

-erature. When takingmeasurement for steelparts in high

temperature, this methodmay be adoptedto obtain the

correct reading.

4.8 High acousticreduction material

For materials infiber, poriferousor big granular, acoustic disp-

-ersion will causethe energy attenuationthat may result in

abnormal readings(practically thereading less thanthe actual

thickness), in thiscase the materialis not suitablefor the unit.

4.9 Reference sampleblock

For calibration forthe gauge, agiven thickness orsound veloc-

-ity of thematerial is veryimport. Calibration needsat lest one

referring standard sampleblock. This gauge is provided with a

4.0mm sample block,please check forcalibration operations.

In different material & situation, only one sample block may not

satisfy every calibration.The more similar sample block, the

more exact readingobtained. Ideally, referring block is a group

of different thickness and same material, by calibrating to the

referring block, theeffect of variation of sound velocity will be

minimized. To get themost exact measure, a set ofreferring

block is veryimportant.

When measuring thinmaterial which thicknessclose to the

minimum limit rangeof this unit,please use areferring block to

define exact limitof this material.Do not measuringthe

material that thethickness under theminimum limit.

4.Measurement Tips

4.1 Cleaning surface

Before measuring, thedust, dirt, rustingand grease etcthat

adheres on thehardware/workpiece must beremoved off and

cleaned.

4.2 Decreasing theroughness of surface

Toorough surface mayresult in measureerror/ fault reading.

Please try tomake the surfacesmooth by milling,polishing,

filling or usinghigh viscosity couplingagent.

4.3 Rough machiningsurface

The regular tinytexture/slots resulting formrough machining

process may causeerror, andthe compensation methodis the

same as in4.2, adjusting theangle between thecrosstalk segr-

-egating board ofthe transducer ametal membrane crossing

the detector bottomcentre and lineartexture/slots (parallel or

vertically) may alsoget a betterresult.

4.4 Measuring pipeand tubing

When measuring cylindricalparts to determinethe thickness

of the pipewall, orientation ofthe transducers isimportant. If

the diameter ofthe pipe islarge than approximately4 inches,

measurements should bemade with thetransducer oriented so

that the gapin the wearfaceis perpendicular (atright angle) to

long axis ofthe pipe. Forsmaller pipe diameters,two measure-

-ments should beperformed, one withthe wearface gapperpe-

-ndicular, anotherwith the gapparallel to thelong axis ofthe

pipe. The smaller of the two displayed values should then be

taken as thethickness at thatpoint.

4.5 Complex shapematerial

For complex shapematerial measurement, pleaserefer to the

4.4, the smallerof the tworeading should thenbe taken asthe

thickness.

4.6 Non-parallel surface

Toget a satisfyingultrasonic response, thesurface must have

its one measuringside parallel withanother, otherwisewill

obtain wrong result.
