EARTH RESISTANCE CLAMP YH3002

Advanced Earth Resistance Tester with Double Clamp YH3002
Features:
YH3002 is advanced intelligent Earth Resistance Tester,which is used to measure grounding resistance for grounding pole connected to some conductive part of facility in the power distribution unit of power circuit or building struture,for working grounding(the power distribution unit of power circuit is setting some earth electrode for good operating condition),for safeguard grounding for the thunder and lightning
(It is seted for thunderstruck safeguard facility and the construct rack of the power distribution unit or electric pole tower may be electrified.Therefore,setting safeguard grounding to prevent person and facility from electric damage),for safeguard grounding for the thunder and lightning (It is seted for thunderstruck sateguard facility is discharge),for static electricity safeguard grounding(to prent the inflammable oil,natural gas tin and pipe from static electricity danger),for grouding pole(It is matal conductor that is buried in the soil and directly in touche
.Test voltage have 20v/48v provide choice
.2 pole resistance measurement
.3 pole &4 pole earth resistance measurement
.4 pole soil resistivity testing
.current clamp selection method is used to measuring earth resistance without breaking grouding connection
.double clamp without auxiliary electrode is used to fast measuring ground resistance
.auto and manual contral the test frequency have 94 Hz,105Hz,111Hz,128Hz four frequency provide choice.Automatic frequency control(AFC) IS automatically identified interference frequency and then selected the proper measurement frequency,so that reduced the attect of interference voltage
.automatically measuring the interference voltage and the leakage currenct.The limited value will be alarmed.
.auto power off
.clock display
.double battery power sully and low battery indication
.data storage:can memorize up to 100 measuring values,and uploading to PC by USB2.0 interface.　　There are three models of this series, including Meter A, Meter B and Meter C, which can meet various requirements of different customers. The features are summarized in the following table.
