Chii chinonzi multimeter amplifier chiratidzo?

Iyo multimeter amplifier chiratidzo chakakosha kana iwe uchida kushandisa iyo multimeter nemazvo. A multimeter chishandiso chakakosha chinogona kukubatsira mumamiriro mazhinji. Inogona kushandiswa kuyedza kunaka kwewaya, mabhatiri ekuyedza, uye kuona kuti ndezvipi zvikamu zviri kuita kuti dunhu rako risashande. Nekudaro, kana iwe usinganzwisise ese zviratidzo pane multimeter, hazvizokubatsira zvakanyanya.

Chinangwa chikuru chechiratidzo cheamplifier ndechekuratidza huwandu hwezvino inoyerera kuburikidza nedunhu. Izvi zvinogona kuyerwa nekubatanidza iyo multimeter inotungamira munhevedzano nedunhu uye kuyera kudonha kwevolti pavari (mutemo waOhm). Chiyero chechiyero ichi mavolts per ampere (V/A). (1)

Chiratidzo cheamplifier chinoreva ampere (A) unit, iyo inoyera magetsi anoyerera kuburikidza nedunhu. Chiyero ichi chinogona zvakare kuratidzwa mumamiliamps mA, kiloamps kA kana megaamps MA zvichienderana nekuti yakakura kana idiki kukosha kwacho.

Tsananguro yemudziyo

Iyo ampere ndiyo SI unit yekuyera. Inoyera huwandu hwemagetsi emagetsi anoyerera nepakati imwe musekondi imwe. Imwe ampere yakaenzana ne6.241 x 1018 maerekitironi anopfuura neimwe nzvimbo musekondi imwe. Mune mamwe mazwi, 1 amp = 6,240,000,000,000,000,000 maerekitironi pasekondi.

Resistance uye voltage

Resistance (Resistance) inoreva kushorwa kwekufamba kwezvino muchikamu chemagetsi. Resistance inoyerwa muohms uye pane hukama huri nyore pakati pemagetsi, ikozvino uye kuramba: V = IR. Izvi zvinoreva kuti iwe unogona kuverenga ikozvino mune amps kana iwe uchiziva voltage uye kuramba. Semuenzaniso, kana paine 3 volts ine kushorwa kwe6 ohms, ikozvino ikozvino 0.5 amperes (3 yakakamurwa ne6).

Amplifier multiplier

m = milli kana 10 ^-3
u = diki kana 10^-6
n = nano kana 10^-9
p = pico kana 10^-12
k = kilogram uye zvinoreva "x 1000". Saka, kana ukaona chiratidzo kA, zvinoreva kuti x kukosha 1000

Pane imwe nzira yekuratidza magetsi emagetsi. Iwo anonyanya kushandiswa zvikamu zve metric system ndeye ampere, ampere (A), uye milliamp (mA).

Formula: I = Q/t apo:
I = magetsi azvino muamps (A)
Q = kuchaja muma coulombs (C)
t= nguva yepakati mumasekonzi (s)

Rondedzero iri pazasi inoratidza akawanda eanowanzo shandiswa akawanda uye submultiples yeampere:

1 AMAI = 1,000 Ohm = 1 kOhm
1 mkOm = 1/1,000 Ohm = 0.001 Ohm = 1 mOm
1 nOhm = 1/1,000,000 0 XNUMX Ohm = XNUMX

Zvidimbu

Mamwe mapfupiso akajairwa anoreva magetsi aungasangana nawo. Vari:

mA - milliamp (1/1000 amp)
μA - microampere (1/1000000 ampere)
nA - nanoampere (1/1000000000 ampere)

Nzira yekushandisa sei ammeter?

Ammeters anoyera huwandu hwezvino kana kuyerera kwemagetsi muma amps. Ammeters akagadzirwa kuti abatanidzwe munhevedzano nedunhu ravari kutarisa. Iyo ammeter inopa kuverenga kwakanyanya kana dunhu richimhanya rakazara kana uchiverenga.

Ammeters anoshandiswa mumhando dzakasiyana dzemagetsi nemagetsi ekushandisa, kazhinji sechikamu chezvimwe zvakaoma zviridzwa senge multimeter. Kuti uone kuti ndeapi saizi ammeter inodiwa, iwe unofanirwa kuziva iyo yakakwira inotarisirwa ikozvino. Iyo yakakwirira nhamba yeamps, yakafara uye yakakora waya inodiwa kuti ishandiswe mumamita. Izvi zvinodaro nekuti high current inogadzira magnetic field inogona kukanganisa kuverenga mawaya madiki.

Multimeters inosanganisa akati wandei mabasa mumudziyo mumwe, kusanganisira voltmeters uye ohmmeters, uye ammeters; izvi zvinoita kuti zvive zvakakosha kune zvakasiyana-siyana zvekushandisa. Iwo anowanzo shandiswa nevemagetsi, mainjiniya emagetsi uye vamwe vatengesi.

Tarisa zvimwe zvezvinyorwa zvedu pazasi.
