Yuav ua li cas siv ib tug multimeter los kuaj xyuas cov kab txuas?
Teb: Ib tug choj pawg yeej tseem ceeb encapsulates ib tug choj rectifier Circuit Court nyob rau hauv ib tug yas casing, uas tsis tsuas yog txo qhov chaw nyob los ntawm diodes nyob rau hauv lub luam Circuit Court board, tab sis kuj simplifies lub Circuit Court. Cov tsos thiab sab hauv Circuit Court ntawm tus choj pawg tau pom hauv daim duab 3-12. Feem ntau, cov cim rau AC voltage input thiab DC voltage tso zis yog cim rau ntawm sab nrauv ntawm tus pins sib thooj ntawm tus choj pawg.
Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhim kho tus choj zoo, nws tuaj yeem pom los ntawm cov qauv kev sib txuas ntawm tus choj rectifier Circuit Court uas siv plaub tus pins ntawm tus choj tuaj yeem kuaj pom plaub lub diodes hauv tus choj, siv tib txoj kev los kuaj xyuas cov diodes zoo tib yam.
Tsis tas li ntawd, yog tias muaj kev puas tsuaj rau tus choj pawg tau pom thaum lub sijhawm kho, lub tshuab multimeter tuaj yeem siv los xyuas seb nws puas yog qhov qhib Circuit Court lossis luv Circuit Court txhaum. Yog hais tias qhov qhib Circuit Court txhaum tshwm sim, lub rectifier diode nrog tib qhov rov qab voltage thiab tam sim no raws li tus choj pawg tuaj yeem txuas nrog tus pin sib txuas ntawm lub diode sab hauv puas, uas tuaj yeem ua kom muaj kev ua haujlwm zoo ntawm tus choj pawg.
Yuav siv digital multimeter los ntsuas qhov kub li cas?
Digital multimeter, siv tus pas ntsuas kub built-in, tus qauv thermocouple thiab ntsuas kub converter. Chav tsev ntawm qhov kub thiab txias tuaj yeem nyeem ncaj qha hauv Celsius ntsuas qhov ntsuas kub thiab Fahrenheit ntsuas kub ntsuas ℉, thaum muab qhov ntsuas kub tsis raug them nyiaj ua haujlwm. Thaum paub qhov yuam kev ntawm qhov kev sojntsuam, qhov tseeb thiab qhov ntsuas kub tiag tiag tuaj yeem pom ncaj qha los ntawm kev teeb tsa. Kev ua haujlwm yog raws li nram no:
(1) Txuas cov plugs ntawm ob qho kawg ntawm lub thermocouple mus rau qhov chaw nres nkoj hluav taws xob nrog qhov zoo thiab qhov tsis zoo polarity.
(2) Tig lub pob qhov rooj mus rau qhov kub thiab txias ntawm Celsius degrees Celsius. Lub pob xiav nyob rau sab xis ntawm lub ntsuas vaj huam sib luag tuaj yeem hloov qhov ntsuas kub mus rau Fahrenheit.
(3) Nrog xoom taw tes them nyiaj ua haujlwm, nias lub teeb daj teeb thiab lub teeb ci tom qab ib txhij kom nkag mus rau hom kev hloov kho. Los ntawm kev siv lub nce thiab nqis xub hloov cov yuam sij nyob rau sab xis sab xis, qhov kev siv xoom taw tes tuaj yeem hloov kho ob qho tib si.
(4) Thaum qhov kev hloov kho tiav thiab paub tseeb, thov nias lub pob teeb daj thiab lub teeb nraub qaum ib txhij.
(5) Nias lub teeb daj teeb thiab Hz feem pua ms tus yuam sij kom tawm ntawm kev hloov kho.
