Yuav ua li cas ntsuas tsis kam thiab xaim txuas ntxiv nrog clamp ammeter
Kev ntsuas hluav taws xob:
① Tig qhov hloov mus rau qhov hluav taws xob tsis kam ntawm qhov tsim nyog.
② Khaws qhov hloov pauv hauv lub xeev tso tawm.
③ Cov hlau lead kuaj liab txuas nrog lub davhlau ya nyob twg "Ω", thiab cov hlau kuaj dub txuas nrog lub davhlau ya nyob twg "COM".
④ Cov kev xeem liab thiab xim dub tau txuas nrog rau ob qhov kawg ntawm cov hlau hauv kev sim. Thaum ntsuas qhov tsis kam ntawm cov hlau hauv kev siv, cov kab yuav tsum tau txiav tawm ntawm lub hwj chim ua ntej, thiab lub capacitance txuas nrog cov hlau yuav tsum tau muab tso tawm tag nrho ua ntej ntsuas.
Hlau Txuas Txuas Test
① Tig qhov hloov mus rau 200Ω (los yog buzzer).
② Cov kev xeem liab thiab dub yog txuas nrog rau qhov kawg "Ω" thiab "COM" kawg.
③Yog qhov kev tawm tsam ntawm qhov kev xeem liab thiab xim dub yog tsawg dua (50 ± 25)Ω, lub buzzer built-in yuav ua suab nrov.
