Ua haujlwm nrog digital multimeters
1. Kev ntsuas hluav taws xob
For example, to measure the voltage on a certain line, turn the multimeter to the corresponding voltage level, and then connect the two test leads to the two ends of the line under test, and the measured data can be seen through the display screen.
2. Cable continuity test
Yog tias txoj kab raug txiav tawm, sim qhov kev tawm tsam ntawm ob qho kawg kom tsis muaj kev tawm tsam. Yog tias ob txoj kab txuas nrog ua ke, qhov kev sim tawm ntawm qhov yuav ua rau lub suab nrov, thiab qhov tsis kam yuav yog xoom thaum kuaj nrog cov ntaub ntawv tsis kam.
3. Kev ntsuas ntsuas
Tig lub multimeter mus rau cov iav tiv thaiv, ntsuas ob qhov kawg ntawm qhov kev tawm tsam nrog ob qhov kev xeem coj, thiab nyeem tus nqi ntawm cov zaub.
4. Kev ntsuas tam sim no
Tig lub multimeter mus rau lub iav tam sim no thiab nyob deb ntawm qhov tsim nyog, tom qab ntawd ntxig ob qhov kev xeem coj mus rau hauv lub qhov tam sim no thiab txuas rau lawv hauv cov kab sib txuas rau hauv Circuit Court, thiab ua kom lub zog ntawm lub voj voog los ntsuas qhov tam sim no hauv Circuit Court.
Los ntawm cov lus qhia saum toj no rau kev siv digital multimeters, kuv ntseeg tias txhua tus neeg muaj kev nkag siab zoo ntawm digital multimeters. Nrog rau kev siv ntau dua thiab kev xyaum, koj yuav paub sai sai rau kev siv tshwj xeeb ntawm digital multimeters.
