Lub suab nrawm hloov kho thiab sojntsuam xaiv ntawm ultrasonic thickness gauge
1. Kev hloov suab nrawm: Yog tias lub suab nrawm ntawm lub ntsuas ntsuas ultrasonic thickness hloov, qhov ntsuas tus nqi yuav hloov. Piv txwv li, thaum kho lub suab nrawm, nias qhov "ENTER" tus yuam sij kom kho lub suab nrawm mus rau 5900M/S. Xaiv "Sound Speed" lossis "Sound Speed Adjustment" hauv cov ntawv qhia zaub mov, nias thiab tuav lub "CAL" lossis "Calibration" yuam sij li ob vib nas this, lub suab nrawm yuav raug kho sai sai rau 5900M/S, thiab tom qab ntawd nias qhov "ENTER" lossis "Confirm" kom rov qab mus rau qhov ntsuas ntsuas. Yog tias tseem muaj qhov yuam kev hauv kev ntsuas, lub LCD ntawm cov qauv ntsuas ntsuas ntawm lub ntsuas ntsuas yuav tsum tso "4.0" lossis "4.{11}}mm". Yog tias nws yog tus lej, nias thiab tuav tus yuam sij "CAL" lossis "Calibration" li 2 vib nas this thaum ntsuas qhov ntsuas ntsuas. , kom txog thaum tus lej dhau los ua "4.0" lossis "4.00mm", uas yog, qhov ntsuas ntsuas tau ua tiav thiab qhov ntsuas tau ua tiav.
2. Kev sojntsuam xaiv: Ultrasonic thickness gauge probes feem ntau yog cais raws li kev ua tau zoo thiab txoj kab uas hla mus rau 7MHz/φ6mm sojntsuam, 5MHz/φ10mm sojntsuam, 2.5MHz/φ14mm sojntsuam, thiab 5MHz/φ8mm. Ua ntej siv ib qho kev sojntsuam, koj yuav tsum xub xaiv qhov kev sojntsuam sib thooj ntawm lub ntsuas. Nias lub "ENTER" lossis "Confirm" khawm kom txuag tau. Lwm zaus koj qhib lub computer, qhov kev sojntsuam yuav yog tus sojntsuam xaiv lub sijhawm no. Txhawm rau kom ntseeg tau tias ntsuas qhov tseeb thiab ruaj khov, nws raug nquahu kom tsis txhob cuam tshuam kev sojntsuam. Tom qab siv lub ntsuas, cov couplant thiab av ntawm qhov kev sojntsuam thiab ntsuas yuav tsum tau muab tshem tawm.
Thickness gauge calibration tswv yim
1. Siv tus ntaiv ntsuas ntsuas ntsuas ntsuas thaum lub thickness yog ze rau qhov siab tshaj tus nqi thiab qhov tsawg kawg nkaus tus nqi ntawm cov thickness yuav tsum tau ntsuas (los yog 1/2 ntawm qhov siab tshaj tus nqi ntawm cov thickness yuav tsum tau ntsuas);
2. Muab qhov kev sojntsuam rau ntawm qhov ntsuas tuab tuab thiab kho qhov "Sound Velocity Correction" pob qhov rooj kom lub thickness gauge qhia ib qho kev nyeem ze rau tus nqi paub;
3. Muab qhov kev sojntsuam rau ntawm qhov ntsuas nyias nyias thiab kho qhov "zero kho" pob qhov rooj kom lub thickness gauge zaub nyeem ze rau tus nqi paub;
4. Kho dua tshiab kom tau txais cov ntawv nyeem kom raug ntawm ob qhov siab thiab qis kawg ntawm qhov ntsuas qhov ntsuas, thiab tam sim no qhov ntsuas tau debugged;
5. Yog tias lub suab nrawm ntawm cov khoom paub, lub suab ceev tus nqi tuaj yeem hloov kho ua ntej, thiab tom qab ntawd ntawm qhov ntsuas ntsuas txuas nrog lub ntsuas ntsuas, kho qhov "zero calibration" knob kom lub ntsuas ntsuas ntsuas qhov tuab ntawm qhov ntsuas. thaiv, thiab qhov ntsuas tau debugged.
