Description: Three-wire grounding Resistance Tester with Earthing Resistance Range 0.01~3000Ω Application Scenarios: Digital grounding resistance tester, also known as the three-wire grounding resistance tester, grounding resistance meter, etc., is a commonly used meter for measuring grounding resistance. It adopts a large LCD gray-white screen backlight display and microprocessor technology to meet the requirements of two-wire and three-wire test resistance. Suitable for telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, factory grounding networks, lightning rods and so on. Instrument testing is precise, fast, simple, stable and reliable. The digital grounding resistance tester is controlled by the microprocessor and can automatically detect the connection status of each interface and the interference voltage and interference frequency of the ground network, and has the function of testing the auxiliary grounding resistance value. At the same time store 500 sets of data, resistance measurement range: 0.01Ω ~ 3000Ω, grounding voltage range: 0.01 ~ 600.0V Main Features Earthing Resistance Range0.01Ω~3000Ω Accuracy±1.5%rdg±5dgtGround resistance resolution0.01ΩGrounding voltage range0.01~600V AC Accuracy±1.5%rdg±3dgtGround voltage resolution0.01VReference conditions23°C±5°C, 75%rh or less (Auxiliary earth resistance 100Ω±5%, voltage to ground <10V)FunctionEarth ground resistance measurement, voltage to ground measurement, low value resistance measurementPower SupplyDC 6V 1.5V LR14 batteryBacklightControllable gray screen backlight, suitable for use in dim placesMeasuring ModePrecise 3-pole measurement, simple 2-pole measurementMeasuring MethodEarth ground resistance: rated current change-pole method, Test current >20mA (sine wave),128Hz;Voltage to ground: average value rectificationWire Resistance VerificationAvoid error caused by testing wire that is failed to be fully inserted into tester interface or by poor contact or by users’ replacing or lengthening testing wires, making it more accurate for earth ground resistance measurement.Display Mode4-digital super-large LCD display, gray screen backlightMeasuring indicatorDuring measurement, LED flash indicator, LCD count down displayLCD Dimension108mm×65mmDimensionL×W×H: 240mm×188mm×85mmTesting WiresThree wires: each for Red 15m, Yellow 10m, and Green 5mSimple Testing Wire2 wires: each for Red 1.5m and Green 1.5mAuxiliary earthing rod2 PCSMeasuring RateVoltage to ground: about 2 times/second; earth ground resistance: about 5 seconds/timeMeasuring TimesOver 5000 timesCircuit VoltageMeasuring voltage to ground: measuring below AC 600VData Storage500 sets, flash display “FULL” icon to indicate storage is fullData ReadData read function: “MR” icon displayOverflow DisplayExceeding measuring range overflow function: “OL” icon displayAlarm FunctionWhen measuring value exceeds alarm setting value, there is beeper alarmingBattery VoltageBattery power indicate in real time, the battery voltage is low and remind to charge in timePower ConsumptionBacklight:25mA MaxStandby: 25mA Max(Backlight shut off)Measurement:70mA Max(Backlight shut off)WeightTester:1230g (including battery)Testing Wires:610g (including simply testing wires)Auxiliary earthing rod:360g(2 PCS)Meter bag:1200gWorking Temperature & Humidity-10℃~40℃;below 80%rhStorage temperature & humidity-20℃~60℃;below 70%rhOverload ProtectionMeasuring earth resistance: between each interfaces of E-H、E-S, AC 280V/3 secondsInsulation ResistanceOver 10MΩ(between circuit and enclosure it is 500V)Withstanding VoltageAC 3700V/rms (Between circuit and enclosure)Electromagnetic FeaturesIEC61010-4-3, radio frequency electromagnetic field ≤ 1V/mProtection TypeIEC61010-1、IEC1010-2-31、IEC61557-1,5、IEC60529(IP54)、Pollution grade 2、CAT Ⅲ 300V
