Kev faib tawm ntawm Kev Siv Hluav Taws Xob Hluav Taws Xob Meters

(1) Cov ntsuas hluav taws xob hluav taws xob tuaj yeem muab faib ua DC hluav taws xob ntsuas hluav taws xob thiab AC hluav taws xob ntsuas hluav taws xob raws li cov hluav taws xob uas lawv siv. AC hluav taws xob ntsuas hluav taws xob tuaj yeem muab faib ua ib zaug -theem hluav taws xob ntsuas hluav taws xob, peb-theem peb-hlau hluav taws xob ntsuas hluav taws xob thiab peb-theem plaub- xaim hluav taws xob hluav taws xob ntsuas raws li lawv cov kab theem.

(2) Cov ntsuas hluav taws xob hluav taws xob tuaj yeem muab faib ua hluav taws xob- cov tshuab hluav taws xob hluav taws xob ntsuas hluav taws xob thiab hluav taws xob hluav taws xob ntsuas hluav taws xob (tseem hu ua hluav taws xob hluav taws xob zoo li qub, khoom siv hluav taws xob- lub xeev hluav taws xob ntsuas hluav taws xob) raws li lawv cov qauv kev ua haujlwm . Electromechanical hluav taws xob ntsuas hluav taws xob siv hauv AC circuits raws li cov khoom siv hluav taws xob zoo tib yam ntsuas, thiab feem ntau siv cov ntsuas hluav taws xob inductive. Cov ntsuas hluav taws xob hluav taws xob tuaj yeem muab faib ua cov ntsuas hluav taws xob tag nrho thiab cov ntsuas hluav taws xob hluav taws xob.

(3) Cov ntsuas hluav taws xob hluav taws xob tuaj yeem muab faib ua ib qho hluav taws xob ntsuas hluav taws xob thiab faib hluav taws xob ntsuas hluav taws xob raws li lawv cov qauv.

(4) Cov ntsuas hluav taws xob hluav taws xob tuaj yeem muab faib ua hluav taws xob hluav taws xob ntsuas hluav taws xob, hluav taws xob hluav taws xob ntsuas hluav taws xob, ntsuas qhov xav tau siab tshaj plaws, cov ntsuas hluav taws xob hluav taws xob hluav taws xob, ntau- lub sijhawm sijhawm- ntawm- siv hluav taws xob cov ntsuas hluav taws xob, hluav taws xob hluav taws xob them ua ntej, ntsuas hluav taws xob poob thiab ntau- siv hluav taws xob ntsuas hluav taws xob raws li lawv siv. Tos.

(5) Cov ntsuas hluav taws xob hluav taws xob tuaj yeem muab faib ua cov ntsuas hluav taws xob zoo tib yam (0.2, 0.5, 1.0, 2.0, 3. {{10}} qib) thiab portable precision hluav taws xob ntsuas hluav taws xob (0.01, 0.02, 0.05, 0.1, 0.2 qib) raws li lawv cov qib raug.
