Advanced Function Nta ntawm Digital Multimeters
Los ntawm kev tswj circuits mus rau cov khoos phis tawj me me, kev sib xyaw ua ke ua rau cov cuab yeej digital niaj hnub muab kev ua haujlwm ntau dua.
Cov kev ntsuas kev txhim kho uas muaj xws li:
Tam sim no - txwv tsis pub semiconductor junction voltage poob ntsuas, siv los txiav txim seb hom transistor;
Graphical zaub ntawm cov ntsuas ntsuas, xws li histograms;
Yuav ua kom mus / tsis tau - mus ntsuas tau yooj yim dua;
Kev ntsuas tsis tu ncua, thiab suab tswb thaum lub voj voog tshwm sim;
tsawg zaus oscilloscope;
xov tooj kuaj ntaus ntawv;
Kev ntsuas hluav taws xob tsis siv neeg, suav nrog lub sijhawm tsis siv neeg, ncua cov teeb liab, thiab lwm yam .;
Kev tshawb nrhiav cov ntaub ntawv yooj yim ua haujlwm, xws li sau qhov siab tshaj plaws thiab qhov tsawg kawg nkaus nyeem ntawv rau lub sijhawm teev tseg, lossis noj qee cov qauv nyeem ntawm ib ntus.
Qauv thiab tuav kom kaw qhov kev nyeem ntawv kawg rau kev nyeem ntawv tom qab lub cuab yeej raug tshem tawm ntawm qhov ntsuas hluav taws xob;
Qhov ntsuas qhov ntsuas tau hloov pauv hloov pauv, thiab lub ntsuas ntsuas tau xaiv qhov ntsuas qhov tsim nyog thaum ntsuas los tiv thaiv lub ntsuas ntsuas los ntawm kev puas tsuaj.
Digital multimeters feem ntau muaj circuitry lossis software uas tuaj yeem ua kom ntsuas qhov tseeb ntawm AC voltage ntawm txhua zaus. Hom multimeter no siv txoj kev rms los ua ke cov teeb liab tawm tswv yim, yog li txawm tias lub teeb liab tawm tswv yim tsis yog qhov zoo tshaj plaws sine yoj, nws tuaj yeem nyeem cov nqi hluav taws xob tiag tiag.
Qee qhov niaj hnub multimeters tuaj yeem txuas nrog lub khoos phis tawj ntawm tus kheej ntawm infrared, RS-232 lossis IEEE-488 ntaus ntawv tsheb npav, thiab lwm yam. Nyob rau hauv txoj kev no, lub khoos phis tawj tuaj yeem sau cov ntawv nyeem thaum ntsuas, lossis xa cov txiaj ntsig ntawm lub cuab yeej mus rau lub computer. .
Modern equipment and systems are becoming more complex, and the multimeter is becoming less common in the technician's toolbox; more complex and specialized equipment is replacing it. For example, when measuring an antenna, a worker might have used an ohmmeter to measure its resistance; a modern technician might use a handheld analyzer to test several parameters to determine the integrity of the antenna cable.
