TAROZIDA TORTISH QOIDALARI

  1. Taroziny bir joydan ikkinchi joyga ko’chirishga ruxsat etilmaydi.

  2. Tarozida tortishdan avval uning to’g’ri ekanligiga ishonch hosil qilish kerak; buning uchun arretir dastasini (diskini) sekin, siltamasdan o’ngga burab, ko’rsatkich harakati kuzatiladi. Agar ko’rsatkichning nol nuqtaga nisbatan o’ng va chap tomonga harakat qi-
    lishi bir xil bo’lsa yoki bir-biridan yarim darajaga farq qilsa, uni «to’g’ri tarozi» deyish mumkin.

  3. Agar tarozi muvozanat holatga kelmasa, uni qo’l bilan ushlab nolga keltirish yaramaydi, bunday holatda tarozi ostidagi maxsus vintlarni burab, tarozini gorizontal vaziyatga keltirish tavsiya etiladi.

  4. Taroziga issiq yoki iflos buyum yoki moddalarni qo’yish va toshlarni qo’l bilan olish mumkin emas; tosh o’ng pallaning o’rtasiga, tortiladigan modda tarozi
    chap pallasining o’rtasiga qo’yiladi. Tortiladigan modda to’g’ridan-to’g’ri pallaga qo’yilmaydi, bunda ma'lum bir idish, byuks, soat oynasi yoki qog’ozdan foydalanish kerak.

  5. Taroziga yuk va tosh qo’yishda, shuningdek ularni tarozidan olish vaqtida tarozi arretirda bo’lishi kerak. Aks holda prizmaning qirrasi tez eyilib, tarozining aniqligi kamayadi.

  6. Tarozi pallasiga toshlarni ma'lum tartibda, eng og’iridan boshlab qo’yish va shu tartibda olish tavsiya hilinadi.

  7. Bir tajribani ohirigacha bajarishda bitta tarozi va bitta qutichadagi toshlardan foydalanish tavsiya etiladi.

8. Tortish tugagandan keyin tarozining arretirini burab, g’ilofning eshigini berkitish zarur.
