Qhov zoo thiab qhov tsis zoo ntawm digital multimeter thiab pointer multimeter
Multimeters, muab faib ua digital multimeter thiab pointer multimeter, yog qhov tseem ceeb ntsuas ntsuas hauv hluav taws xob hluav taws xob thiab lwm yam haujlwm. Lawv feem ntau yog siv los ntsuas qhov voltage, tam sim no, thiab tsis kam, thiab yog cov cuab yeej siv ntau yam thiab ntau yam ntsuas. Ob qho tib si digital thiab ib txwm siv lub luag haujlwm tseem ceeb hauv kev ntsuas, tab sis lawv qhov zoo thiab qhov tsis zoo piv rau ib leeg yog dab tsi?
Pointer Multimeter:
1. Ib tug pointer multimeter yog ib qho nruab nrab hom ntsuas nrog intuitive thiab pom kev nyeem ntawv indications.
2. Ib tug pointer multimeter feem ntau tsis muaj lub amplifier nyob rau hauv, yog li lub internal kuj yog me me.
3. Cov yam ntxwv zaus ntawm tus pointer hom multimeter yog qhov tsis sib xws vim nws qhov kev ua haujlwm me me thiab kev siv cov khoom sib cais los ua ib qho shunt thiab voltage divider circuit.
4. Cov qauv sab hauv ntawm lub pointer hom multimeter yog qhov yooj yim, yog li nws muaj tus nqi qis dua, kev ua haujlwm tsawg dua, kev saib xyuas yooj yim, thiab muaj zog overcurrent thiab overvoltage peev xwm.
5. Lub pointer hom multimeter muaj qhov tso zis siab voltage thiab tam sim no, ua kom yooj yim rau kev sim thyristor, LED, thiab lwm yam.
Digital Multimeter:
1. Ib qho digital multimeter yog ib qho ntsuas ntsuas tam sim uas siv cov qauv coj txhua txhua 0.3 vib nas this los tso saib cov txiaj ntsig ntsuas, uas tsis yooj yim npaum li hom pointer rau kev nyeem ntawv.
2. Vim yog kev siv sab hauv ntawm lub chaw ua haujlwm amplifier Circuit Court, cov digital multimeter tuaj yeem muaj qhov loj hauv kev tiv thaiv, uas tuaj yeem muaj kev cuam tshuam me me rau qhov ntsuas hluav taws xob thiab ntsuas qhov tseeb dua.
3. Lub tshuab digital multimeter siv ntau yam hauv oscillation amplification, zaus faib, tiv thaiv circuits, thiab lwm yam, yog li nws muaj ntau yam haujlwm.
4. Vim yog siv cov kev sib xyaw ua ke hauv cov qauv sab hauv ntawm lub tshuab digital multimeter, nws lub peev xwm overload tsis zoo thiab feem ntau tsis yooj yim kho tom qab kev puas tsuaj.
5. Cov zis hluav taws xob ntawm lub tshuab hluav taws xob digital yog qhov tsawg (feem ntau tsis tshaj 1 volt), ua rau nws tsis yooj yim rau kev sim qee yam khoom siv hluav taws xob tshwj xeeb, xws li thyristors, lub teeb-emitting diodes, thiab lwm yam.
