1000 ohm Digital Earth Clamp Meter

ETCR2000 series Earth Clamp Meter is widely used in the grounding resistance measurement of electric power, telecommunications, meteorology, oilfield, construction and the industrial and electrical equipment.> The measurement does not require disconnecting the grounding wire, need no auxiliary electrode.
> It is safe, fast and simple in use.
> It equips long jaws or round jaws. Long jaw is particularly suitable for the occasion of grounding with the flat steel.
> It also be able to measure the leakage current and the neutral current in the grounding system.Series product parameters table as following:ModelJaws sizeResistance rangeCurrent rangeData uploadAlarmData saveETCR2000ALong type 65x32mm0.01Ω-200ΩxxxxETCR20000.01Ω-1000ΩxxxxETCR2000C0.01Ω-1000Ω0.00mA-20.0Ax√√ETCR2000A+0.01Ω-200Ωxx/√√√ETCR2000+0.01Ω-1200Ωxx/√√√ETCR2000B+0.01Ω-1200Ωxx/√√√ETCR2000C+0.01Ω-1200Ω0.00mA-20.0Ax/√√√ETCR2000E+0.01Ω-1200Ω0.00mA-40.0A√√√ETCR2100ARound type ∮32mm0.01Ω-200ΩxxxxETCR21000.01Ω-1000ΩxxxxETCR2100C0.01Ω-1000Ω0.00mA-20.0Ax√√ETCR2100A+0.01Ω-200Ωxx/√√√ETCR2100+0.01Ω-1200Ωxx/√√√ETCR2100C+0.01Ω-1200Ω0.00mA-20.0Ax/√√√ETCR2100E+0.01Ω-1200Ω0.00mA-40.0A√√√Measuring itemMeasuring rangeResolutionAccuracyResistance0.010Ω-0.099Ω0.001Ω±(1%+0.01Ω)0.10Ω-0.99Ω0.01Ω±(1%+0.01Ω)1.0Ω-49.9Ω0.1Ω±(1%+0.1Ω)50.0Ω-99.5Ω0.5Ω±(1.5%+0.5Ω)100Ω-199Ω1Ω±(2%+1Ω)200Ω-395Ω5Ω±(5%+5Ω)400-590Ω10Ω±(10%+10Ω)600Ω-880Ω20Ω±(20%+20Ω)900Ω-1000Ω30Ω±(25%+30Ω)Current0.00mA -9.95mA0.05mA±(2.5%+1mA)10.0mA -99.0mA0.1mA±(2.5%+5mA)100mA -300mA1mA±(2.5%+10mA)0.30A-2.99A0.01A±(2.5%+0.1A)3.0A-9.9A0.1A±(2.5%+0.3A)10.0A-20.0A0.1 A±(2.5%+0.5A)FunctionGround resistance test, contact resistance testResistance measuring range0.01Ω-1000ΩCurrent measuring range0.00mA-20.0AData storage99Power Supply6VDC 4 PCS of AA Alkaline batteries LR6Alarm Sound and Light"Beep-beep-beep" alarm tone, Alarm Symbol Flashing, Press AL key to turn on, turn off Alarm or set Alarm Threshold.Interference Signal Recognition"Beep-beep-beep" tone, NOISE symbol blinkingWorking Temperature and Humidity-20°c-55°c; 10%RH-90%RHLCD Screen4 Digits LCD display, Screen L*W: 47mm*28.5mmJaw size65mm*32mmJaw opening35mmClamp Weight< 2KG 285mmx85mmx56mmProtection LevelDual InsulationStructural FeatureClamp CTrange ShiftingAutomatic shiftingExternal magnetic field<40A/mExternal electrical field<1V/mSingle measurement time<0.5 secondResistance measurement frequency>1KHzMeasured current frequency50/60Hz Automatic measurementAccessoriesMeter: 1 piece, Test ring: 1 Piece, Meter Suitcase: 1 Piece, Manual 1 Copy
