1.1 DEVICE APPOINTMENT
1.1.1 Appointmentoftheawdetector
The aw detector А1214 EXPERT is related to ultrasonic general-
purposeawdetectorsformanualcontrol.
Theawdetectorisdesignedforsearch,denitionofcoordinatesand
estimationofvariousinfringementssizesincontinuityanduniformityofa
materialinproductsmadefrommetalsandplastic.
The aw detector allows to form, register and keep in non-volatile
memorytimerealizationsofechosignals.Theelectroluminescentdisplay
oftheelectronicblockprovidesdisplayingofechosignalsintheformof
A-involute, and also the images of control objects sections in the form
ofB-scan.Manualandautomaticmeasurementoftimeintervals,signals
amplitudesandautomaticcalculationofdefectscoordinatesareprovided.
ThesoftwareAdvancedDataManager(ADM),includedintotheset
ofdevicedeliveryallowstotransferthedatafromthedevice’smemoryto
theexternalpersonalcomputer(personalcomputer)fortheirsubsequent
analysis and documenting. Also there is a possibility to make device
adjustmentthroughthecomputer,toobserveonthecomputerscreenecho
signalsinrealtimeandscale,toprocessthem(computerawdetector
