ETCR3200 Double Clamp Earth Resistance Tester, through a variety of methods measuring earth resistance (range: 0.01Ω ~ 30.00 kΩ), soil resistivity (range: 0.01Ωm ~ 9000kΩm), earth voltage (range: 0.1 V ~ 100.0 V), grounding lead leakage current, AC current (range: 0.01mA ~ 600A); The tester adopts the precision 4-wire method, 3-wire method, simple 2-wire method, selection method and double-clamp method to measure grounding resistance. Large caliber current clamp design, can measure the grounding system which using large grounding down lead.It can flexibly and accurately measure arbitrary grounding resistance values of single point and mesh grounding and other complex grounding conditions. When measuring parallel grounding, it is unnecessary to disconnect any parallel grounding electrode to maximize the convenience of measurement. Import FFT (fast Fourier transform) technology, AFC (automatic frequency control) technology, ensure the measurement of  high precision, high stability and reliability. ETCR3200 Double Clamp Multi-function Grounding Resistance Tester is composed of host machine, current clamp, monitoring software, test wires, auxiliary ground rod and communication cable. Host machine with large LCD display, white backlight, bar chart indication, clear at a glance. It can store 2000 sets of data at the same time, through the monitoring software to relize historical access and online real-time monitoring functions, dynamic display, alarm indication and auto shut down, with historical data reading, accessing, saving, reporting, printing and other functionsPower Supply DC 9V Alkaline dry cell LR14 1.5V*6PCS, continues standby 300 hoursLCD Size 124mm x 67mm(with backlight)Range Selection measurement method :0.01Ω - 3000ΩDouble clamp measurement method :0.01Ω - 100Ω2/3/4 pole measurement method :0.01Ω - 30.00kΩSoil Resistivity :0.01Ωm - 9000KΩDC Resistance:0.01Ω - 30.00kΩEarth Voltage:0.1V -100.0VAC Current:0.01mA -600AResolution Resistance:0.01ΩSoil Resistivity :0.01ΩmCurrent:0.01mAVoltage:0.1VMax Accuracy ±2%rdg±3dgtData Storage 2000 groupsData Upload RS232 interface, storage data can be uploaded to computer, saved or printed.Automatic Shut Down Automatically shut down after 15 minutes start upPower Consumption Turn on the backlight: 45mA MaxTurn off the backlight : 25mA MaxMeasurement: 100mA Max(Backlight shut off)Working Temperature & Humidity -10℃-40℃, below 80%rhStorage temperature & humidity -20℃-60℃, below 70%rhClamp Caliber Φ68mmMeasuring Method 2/3/4 pole measurement method: Change-pole method, measurement current 20mA MaxSelection measurement method: Change-pole method, measurement current 20mA MaxDouble clamp measurement method: Non-connect mutual inductance method, measurement current 1mA MaxSoil Resistivity: 4-pole measurement (Wenner method)AC current: Mutual inductance method(clamp)Earth Voltage: Average rectification(between P(S)-ES)Test Frequency 128Hz/111Hz/105Hz/94Hz(AFC)Data Model Average value,maximum,minimum valueline resistance check Automatic calibrationMeasuring Rate AC current: about 0.5 times/secondEarth Voltage: about 0.5 times/secondEarth resistance,soil resistivity: about 5 seconds/timeMeasuring Times Over 5000 times (Short-circuit test, interval time should be at least 30seconds)Short-circuit Test Current AC 20mA maxOpen-circuit Test Voltage AC 40V maxTest Voltage Wave Sine waveElectrode Distance Range 1m-100mLine Voltage Measurement below AC 600VData Hold Data hold function: "HOLD" symbol displayData Access Data read function: "READ" symbol displayOverflow Display Exceed measuring range overflow function: "OL" symbol displayAuxiliary Grounding Test With auxiliary grounding resistance test function, 0.00KΩ-30kΩ(100R+rC<50kΩ, 100R+rP<50kΩ)Interference Test Automatic identification of interference signals, "NOISE" symbol indication when the interference voltage is higher than 5VAlarm Function Measuring value exceeds alarm setting value, will ''Toot-toot-toot'' alarm hintBattery Voltage While battery voltage decreases to around 7.5V, will display battery voltage low symbol"     ", and reminding to replace the batteryOverload Protection Measure earth resistance: between each interfaces of E-P.E-E- C,AC 280V/3 secondsInsulation Resistance Over 20MΩ(between circuit and outside shell is 500V)Withstand Voltage AC 3700V/rms.
