 Advanced earth Resistance Tester YH302

The YH302 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 structure,  for working grounding (the power distribution unit of power circuit is setting some earth 

electrode for good operating condition),  for safeguard grounding( if the insulation is damaged,  the metal case of electric facility and the construct rack of the power distribution unit or electric pole tower may be electrified. 

Therefor, setting safeguard grounding to prevent person and facility from electric damage),  for safeguard grounding for the thunder and lightning 

(It is seted for thunderstruck safeguard facility is discharg),  for static electricity safeguard grounding (to prevent the inflammable oil,  natural gas tin and pipe from 

static electricity danger). For grounding pole (It is metal conductor that is buried in the soil and directly in touched with earth),  for grounding wire(It is used to connect the ground terminal of electric facility to grounding pole),  and for the Grounding Net (It is Large-Size horizontal net grounding unit that is consist of vertial grounding pole and horizontal grounding pole used for Power House,  

Transformer Station. The grounding unit has discharge function and Stabilize voltage ) The tester used for the furnish power,  transformer station ,  

it\'s rated AC voltage up to 500KV.

Features

☉ 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 grounding connection

☉ Double clamp without auxiliary electrode is used to fast measuring grounding resistance

☉ Auto and manual control the test frequency have 94Hz, 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  affect of interference voltage.

☉ Automatically measuring the interference voltage and the leakage current. The limited value will be alarmed.

☉ Auto power off

☉ Clock display

☉ Double battery power supply and low battery indication

☉ Data storage:Can memorize up to 100 measuring values,  and uploading to PC by USB2.0 interface.
