HZ-3340S Dual Channel 40A Transformer DC Resistance Tester

I.Gmuaj zog

Lub tuam txhab Huazheng tau tsim cov tiam tshiab HZ-3340S series DC resistance test meter raws li nws tus kheej technology kom zoo dua. Cov cuab yeej siv tshiab lub cim thib peb ntawm lub zog thev naus laus zis, uas yog tus yam ntxwv nrog lub ntim me me, lub teeb yuag, cov zis siab tam sim no thiab lwm yam. Lub tshuab tag nrho yog tswj los ntawm ib qho chip microcomputer, uas muaj kev tshuaj xyuas tus kheej, cov ntaub ntawv txheej txheem, thiab lwm yam. functions, nws kuj muaj tsis siv neeg paug thiab paug qhia thiab lwm yam functions. Kev ntsuas qhov tseeb ntawm qhov ntsuas yog siab, kev ua haujlwm yog qhov yooj yim thiab yooj yim, thiab nws tuaj yeem paub qhov ntsuas nrawm ntawm transformer DC tsis kam.

II.Kev ua tau zoo

1. High tso zis tam sim no ntawm lub ntsuas (Max. tam sim no cov zis muaj peev xwm ncav cuag 40A), siab them voltage (50V).

2. Kev ntsuas dav dav (0Ω-40kΩ), uas tuaj yeem ntsuas transformer, tam sim no thiab voltage transformers thiab lwm yam. tag nrho inductive DC kuj.

3. Lub tshuab yog nruab nrog tsis siv neeg pab sib nqus muaj nuj nqi, aiming ntawm kev xeem winding ntawmtsibkemhlau tub ntxhais uas tsis muaj hluav taws xob lub kaum sab xis YND11 loj muaj peev xwm transformer, high-low-voltage serial excitation method yog saws los kuaj, winding txuas tau txais raws li cov theem hauv cov cuab yeej, thiab ntsuas ceev thiab raug ntsuas ntawm qhov hluav taws xob qis winding tuaj yeem ua tiav. Kev xav tau ntawm lub sijhawm ntawm qhov ntsuas kub nce ntawm transformer tuaj yeem ua tau raws li,dual channelsthiabkev xaiv theemKev ntsuas, peb hom kub nce lub sij hawm tus nqi hom, lub sij hawm tiag tiag sampling thiab luam tawm tuaj yeem pom tau, uas ua rau qhov ntsuas kub nce siab yog qhov yooj yim thiab yooj yim.

4. Nruab nrog kev tiv thaiv zoo tshaj plaws, lub tswb nrov tawm, kom meej meej uas txo qis kev ua haujlwm tsis zoo.

5. Muaj yeeb yuj lub vijtsam loj thiab kov tswj, uas yooj yim thiab yooj yim, thiab cov ntaub ntawv tso tawm kom pom tseeb thiab nyeem tau yooj yim.

6. Cov cuab yeej yog nruab nrog perpetual daim ntawv qhia hnub, 100 pawg ntawm cov ntaub ntawv ib txwm khaws cia, 4 lub sij hawm ntawm qhov kub thiab txias ntsuas cov ntaub ntawv khaws cia, tsis siv neeg kub hloov pauv ua haujlwm nyob rau hauv hom qub, cov ntaub ntawv yuav tsis ploj tom qab kaw. Thiab nruab nrog "U disk" interface los pab txhawb kev xa tawm kub nce cov ntaub ntawv rau kev siv thiab tsim qhov kub nce nkhaus.

7. Cov cuab yeej yog nruab nrog RS485 kev sib txuas lus interface, nyob rau hauv kev sib koom tes nrog manipulation software ntawm lub computer sab sauv kom paub txog tej thaj chaw deb tswj ntsuas.

8. Cov cuab yeej yog nruab nrog tsis siv neeg demagnetization muaj nuj nqi, uas txo cov seem hlau nplaum ntawm lub transformer thiab tsis txhob muaj teeb meem nyob rau hauv switching.
