Yog vim li cas vim li cas lub digital zaub xeem cwj mem qhia pom xob laim
Hais txog cov laj thawj vim li cas tus ntsuas cov duab digital qhia pom xob laim, suav nrog cov lus piav qhia ntawm lub pob, qhov kev tshawb pom ncaj qha, nrhiav tsis tau ncaj qha thiab qhov tawg ntawm qhov ntsuas qhov ntsuas digital, tus tester tsim nyog rau kev txheeb xyuas ncaj qha ntawm 12-250v AC thiab DC thiab indirect nrhiav pom ntawm xoom kab thiab theem ntawm AC kab thiab breakpoints.
Yog vim li cas vim li cas lub digital zaub xeem cwj mem qhia pom xob laim
Yuav ua li cas saib tus cwj mem ntsuas digital, qee zaum nws yog lub cim hluav taws xob, qee zaum nws yog txoj hlua ntawm cov lej tom qab xob laim.
1. Khawm piav qhia
(Ib tus yuam sij) DIRECT, ncaj qha ntsuas khawm (nyob deb ntawm lub vijtsam LCD), uas yog, thaum siv lub taub hau batch ncaj qha mus kov cov kab, thov nias lub pob no;
(B qhov tseem ceeb) KEV PAB CUAM, inductive ntsuas khawm (ze rau ntawm lub vijtsam LCD), uas yog, thaum siv me ntsis kom nkag siab cov kab sib cuag, thov nias lub pob no.
Nco tseg: Txawm hais tias yuav luam tawm ntawm tus cwj mem hluav taws xob li cas, thov nco ntsoov tias qhov deb ntawm lub vijtsam LCD yog qhov ntsuas ncaj qha; ib qho ze rau lub LCD yog tus yuam sij sensor!
2. Lub peev xwm ntawm daim ntawv thov ntawm tus cwj mem xeem
Nws yog qhov tsim nyog rau kev tshawb nrhiav ncaj qha ntawm 12-250v AC thiab DC thiab kev tshawb nrhiav tsis ncaj ntawm cov kab nruab nrab, kab theem thiab qhov tawg ntawm qhov hloov pauv tam sim no. Nws kuj tseem tuaj yeem ntsuas qhov txuas ntxiv ntawm cov conductors tuag.
3. Kev tshawb nrhiav ncaj qha
a. Tus lej kawg yog ntsuas tus nqi hluav taws xob; b. Thaum tus nqi siab-tawg tso tawm tsawg dua 70 feem pua, qhov qis-so nqi yog tso tawm; c. Thaum ntsuas DC, kov lwm tus ncej;
4. Indirect detection: Nias thiab tuav tus yuam sij B, thiab nqa lub taub hau batch ze rau ntawm txoj kab hluav taws xob. Yog tias cov kab hluav taws xob raug them, cov duab ntawm cov cwj mem digital yuav tso tawm cov cim hluav taws xob siab.
5. Kev txheeb xyuas qhov tawg: tuav tus yuam sij B thiab txav mus ntev raws li cov xaim, qhov chaw uas tsis muaj qhov pom ntawm lub qhov rais zaub yog qhov tawg.
1. Vim li cas cov ntawv ntsuas ntsuas digital tsuas tso tawm 12V, tab sis qhov tseeb yog 220V? Muaj ob lub nyees khawm, ib qho yog Direct Test, thiab lwm qhov yog Induction Break-point?
1. Lub qhov rais me me uas tso tawm los ntawm tus cwj mem xeem no yog kab ntawm tus lej preset, uas tsis yog cov lus qhia ntse. Lawv yog 12|36|55|110|220, uas tej zaum yuav yog vim tsuas yog ua tib zoo saib rau tus lej pem hauv ntej thiab tsis xyuam xim rau cov lej tom qab;
2. Hom cwj mem no tsuas yog txiav txim los ntawm kev paub dhau los, nws tsis yog qhov tseeb heev, uas yog, cov lej pom yog siv rau kev siv nkaus xwb, thiab feem ntau ntawm lawv tau tshwm sim ntawm ob kab nyob thiab nruab nrab, tab sis lawv tseem tuaj yeem muab piv nrog. ntawm cov zaub, tsuas yog los ntawm cov kev paub accumulated mus rau "nrhiav" siv; hom kev xeem cwj mem no tsis pom zoo.
2. Nws txhais li cas tias 12 36 55 tshwm rau ntawm cov ntawv ntsuas digital?
Daim ntawv ntsuas ntsuas tus cwj mem, tus lej 12 36 55 tshwm thaum lub sijhawm xeem, qhov no txhais li cas?
12, 36, 55, thiab tus lej kawg yog 220. Qhov no yog qhov siab thiab qis qis uas sawv cev rau qhov ntsuas voltage. Lub sijhawm no, qhov hluav taws xob tso tawm yog 55V. thiab lwm yam. Txawm li cas los xij, tus cwj mem digital no tsis raug thiab tsuas yog siv tau raws li kev siv.
3. Nws txhais li cas thaum lub ntsuas ntsuas ntsuas 12, 36, 55, 110, 220V?
Tus cwj mem ntsuas ntsuas 220v voltage, yog tias ntsuas 110v voltage, nws yuav tso saib: "12, 36, 55, 110", thiab lwm yam.
