Sinov usuli bosqichlari:
1. Sinov uchastkasida sinov nuqtalarini tashkil qilishimiz kerak, ularning masofasi test ehtiyojlariga bog'liq.O'lchov nuqtasi yo'l harakati chizig'ining g'ildirak yo'li kamarida bo'lishi va oq bo'yoq yoki bo'r bilan belgilanishi kerak.2. Biz foydalanadigan sinov mashinasi uchun sinov mashinasining orqa g'ildiragi bo'shlig'i o'lchov nuqtasi orqasida taxminan 3 ~ 5 sm masofada joylashganki, bu bizning tekshiruvimiz uchun qulaydir.3. Keyin, biz burilish o'lchagichni avtomobilning orqa g'ildiraklari orasidagi bo'shliqqa joylashtiramiz, avtomobil yo'nalishiga mos keladi, nur qo'li shinaga tegmasligi kerak, burilish o'lchagich probi o'lchash nuqtasiga joylashtiriladi va terish indikatori burilishda o'rnatiladi Asbobning o'lchash tayog'ida.4. Biz xohlagan og'ish o'lchagichni bir tomondan o'lchash mumkin yoki uni har ikki tomondan nolga qaytarish mumkin, va terish indikatori deflection o'lchagichning o'lchov tayog'iga o'rnatiladi.5. Nihoyat, sinovchi mashinani asta-sekin oldinga siljish uchun buyruq berish uchun hushtak chaladi va yo'l sirtining deformatsiyasi ortishi bilan terish indikatori oldinga aylanishda davom etadi.Qo'l maksimal qiymatga aylanganda, L1 dastlabki o'qishni tezda o'qing.
