HZJD-3002 Ob chav Clamp Multi-function av Resistance Tester
Ob chav Clamp Multi-function av Resistance Tester
I．Introduction
Cov qib siab grounding resistance tester integrates ntau yam kev ntsuas. Ntxiv nrog rau kev ua haujlwm ib txwm muaj ntawm kev ua haujlwm hauv av ua haujlwm, nws kuj tseem muaj qhov tshwj xeeb ntawm kev ntsuas yam tsis muaj kev pabcuam hauv av. Nws siv lub LCD loj grey screen backlight zaub thiab microprocessor technology, los ntawm microprocessor tswj precision 4-wire method, 3-wire method thiab yooj yim 2-xaim txoj kev, xaiv txoj kev, ob chav clamp txoj kev ntsuas grounding resistance test. Loj-inch tam sim no clamp tsim, siv ob lub puab tsaig ntsuas thev naus laus zis, tsis tas yuav tsum tau ntaus lub hauv paus auxiliary, tsis tas yuav tsum tau cais cov av hauv av thiab cov khoom siv kom ua tiav cov kev ntsuas hauv online.Suitable rau kev sib txuas lus, hluav taws xob, huab cua, computer chav, cov roj av, cov kab hluav taws xob, cov kab hluav taws xob ntauwd, cov khoom siv roj av, cov chaw tsim khoom hauv av, cov hlua hluav taws xob thiab lwm yam. Kev ntsuas ntsuas yog qhov tseeb, nrawm, yooj yim, ruaj khov thiab txhim khu kev qha.
Earth Resistance Tester yog tswj los ntawm microprocessor thiab tuaj yeem txheeb xyuas cov av tiv thaiv, av tiv thaiv, av voltage, DC tsis kam thiab AC tam sim no. Nws siv cov txheej txheem lim ceev kom txo qis kev cuam tshuam. Tus nqi tsis kam ntawm cov khoom siv hluav taws xob tau tshwm sim ntawm tib lub vijtsam los pab txhawb kev txiav txim siab ntawm qhov ntsuas qhov yuam kev vim yog ib puag ncig, thiab nws yooj yim los ntsuas qhov tseeb hauv av tiv thaiv ntau dua.Tam sim no khaws 500 cov ntaub ntawv, online saib xyuas cov ntaub ntawv los ntawm kev saib xyuas software, USB cov ntaub ntawv uploaded rau PC thiab cov yam ntxwv tshwj xeeb xws li kev ceeb toom lub tswb.
Earth Resistance Tester muaj cov tswv tsev, saib xyuas software, kab xeem, USB cable, thiab pas nrig hauv av. Nws muaj cov haujlwm ntawm kev nyeem ntawv, txheeb xyuas, txuag, tshaj tawm thiab luam tawm cov ntaub ntawv keeb kwm.
