Insulation Resistance Tester, Clamp Resistance Meter Ground Pile Clamp Ground Resistance Tester Loop Resistance Tester ES3022

Feature:Ground-pile clamp ground resistance tester, also known as loop resistance tester, is used to test ground resistance. This instrument uses a brand new 2.4-inch luxury color screen design, with clamp resistance, three or four wire resistance, AC voltage, current measurement functions, and also has data storage, data access, alarm, automatic shutdown and other functions. The whole machine is beautiful and high-grade, wide range, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance, strong anti-interference ability. Moreover, it has a shock-proof, dust-proof and moisture-proof structure. It is a commonly used and indispensable instrument for telecommunications, electric power, meteorology, computer rooms, oil fields, electromechanical installation and maintenance, and industrial enterprises that use electricity as industrial power or energy. It is suitable for measuring grounding resistance of various telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, transmission lines of iron towers, gas stations, factory grounding grids, lightning rods, etc.The ground-pile clamp ground resistance tester is controlled by a microprocessor and can accurately detect ground resistance. It uses fast filtering technology to minimize interference. At the same time with data storage and data upload functions.Specification:Model：ES3022Clamp resistance Range：0.00Ω-1500Ω 0.00Ω-1800Ω 0.00Ω-2000ΩLeakage current range：0.000mA-40A 0.000mA-50A 0.000mA-60ACurrent resolution：1uA 1uA 1uAThree-four-wire method range：0.00Ω-3000Ω 0.00Ω-30kΩ 0.00Ω-30kΩSoil resistivity range：0.00Ω-9999kΩm 0.00Ω-9999kΩmGround voltage range：600V 600V 600VBluetooth：NOBuilt-in rechargeable battery:YESTFT Color display:YESUSBData upload function:YESdata storage:YESReal-time battery power indicator:YESBacklight:YESAlarm function:YESLow battery voltage indication:YESOverload protection:YESTechnical SpecificationFunction：Ground resistance test, loop resistance test, AC current test, AC voltage testAccuracy guaranteed temperature and humidity：23℃±5℃, below 75%rhPower Supply：DC 3.7 Vlithium batteryResistance resolution：0.01ΩCurrent resolution：0.001mAVoltage resolution：0.01VClamp Size：68mmDisplay：2.4 inch color LCD screenLCD Size：46mm×29mmMeter Dimension：273mm×106mm×53mmmeasure time：1 time/secUSB ：With USB interface,uploaded the data to the computer, saved and printedCommunication line：USB communication line 1Data storage Maximum：100 groups of data, display "FULL" symbol to indicate that the storage is fullOverflow display：“OL” symbol indication when over-range overflowAlarm function：When the measured value exceeds the alarm set value, an alarm will be issuedbattery voltage：Real-time display of battery power, reminding to charge in time when battery voltage is lowAutomatic shut-down Turn off automatically after 15 minutesPower consumption：750mA MAXQuality Meter: 975g (including battery)Working temperature and humidity ：-20℃～50℃; Below 80%rhStorage Temperature and Humidity：-40℃～60℃; below 70%rh Insulation Resistance：20Ω or more (500V between circuit and outside)Pressure Resistance：AC 3700V/rms(between circuit and outside)External magnetic field：＜40A/mExternal electric field：＜1V/mSuitable for Safety Regulations IEC61010-1(CAT Ⅲ 300V、CAT IV 600V、Pollution Degree 2);IEC61010-031；IEC61557-1(Ground resistance)Package List:Meter：1 pcsTest line：4 pcsSimple test line：2 pcsUSB communication line：1 pcsCharger：1 pcsMonitoring software CD：1 pcsInstructions, warranty：1 setInstrument box：1 pcs
