Lub ntsiab lus ntawm txoj haujlwm kho pob zog ntawm lub analog multimeter
Txawv sib txawv cov multimeters tuaj yeem kuaj cov khoom sib txawv, yog li lawv cov lej tseem ceeb thiab kev ua haujlwm kuj sib txawv. Hauv qab no, peb yuav coj ib qho taw tes zoo li ua piv txwv los qhia kev faib tawm ntawm lub cev multimeter (vaj huam sib luag) ntawm ntau lub xov tooj, raws li qhia hauv daim duab. Yog li ntawd, txoj haujlwm hloov lub zog ntawm lub pointer multimeter yuav tsum to taub ua ntej thaum siv nws:
1. Qhov haujlwm tawm yog thaum lub voj voos sab hauv ntawm tus pointer multimeter tau nyob rau hauv lub xeev disconnected. Thaum pululation tsis siv, tig lub pob qhov rooj rau txoj haujlwm no. 2. When measuring AC voltage, select the AC voltage mode (ACV), which has four ranges of "1{{10}}V, 50V, 250V, 1000V" based on the measured voltage value. 3. Thaum ntsuas ntsuas DC tam sim no nrog H-tam sim RLL tam sim no hom (DCA), xaiv hom no thiab faib cov nqi no raws li tus nqi tam sim no: 50MA, 50MA, 500MA, 10A. 4. Thaum ntsuas qhov tsis kam nrog Ohm hom (OHM), xaiv hom no thiab faib cov hom "x1, x 300 thiab lwm hom qauv raws li kev ntsuas tus nqi. 5. Thaum ntsuas qhov ntsuas hluav taws xob trantor (HFE), xaiv lub iav thiab nyeem ncaj qha raws tus lej nyeem ntawv. 6. Xaiv cov iav beep thaum kuaj tau Diode. 7. DC voltage hom (DCV) tau xaiv rau kev ntsuas DC voltage. Raws li qhov ntsuas hluav taws xob ntsuas tau ntsuas, rau qib txuas ntxiv tuaj yeem xaiv: 2.5V, 10V, 250V, thiab 1000V.
