O‘lchash asboblarining asosiy metrologik tavsiflari
Har qanday o‘lchash asbobini tanlashda eng avvalo uning metrologik tavsiflariga e’tibor berishimiz lozim bo‘ladi.
O‘zgartirish funksiyasi – buni analogli o‘lchash asboblarida shkala tenglamasidan ham bilishimiz mumkin. Tanlanayotgan asbobda o‘zgartirish funktsiyasi chiziqli bo‘lishi qaydnomalarni olishni osonlashtiradi, sub’ektiv xatoliklarni esa kamaytiradi
II. Amaliy topshiriq
Misol. Karrali va ulushli birliklarni hosil qiluvchi old qo‘shimchalar.
3 - jadval
T [Tera] = 1012
G [Giga] = 109
M [Mega] = 106
K [Kilo] = 106
G [Gekto] = 102
|
K > 0 - karrali
|
d [detse] = 10-1
s [santi] = 10-2
m [milli] = 10-3
mk [mikro] = 10-6
n [nano] = 10-9
|
K < 0 - ulushli
|
Keltirilgan fizik kattaliklarning qiymatlarini karrali va ulushli birliklar ko‘rinishida ifodalang (3-jadval asosida)
