Contact Type Online Earth Resistance Tester Grounding Voltage Meter Tester RS485

Description: Contact Type Online Earth Resistance Tester Grounding Voltage Meter Tester RS485 Note: Battery cannot be included during the shipping !!! Overview:1. Contact Type On-line Earth Resistance Tester is high-tech product that our company has devoted to "Earth Resistance Detect Technology Research" for more than ten years, Adopt precision 3-wire or simple 2-wire measurement method to test the earth resistance. Adopt average value rectification method to test grounding voltage, online detection, real-time monitoring. User can select RS232 or RS485 communication, according the protocol MODBUS to secondary development, build the network, realize remote multipoint online monitoring etc.2. Contact Type On-line Earth Resistance Tester displayed by super large LCD, very clear and obvious. The alarm critical value can be set via the button, and with the sound and light alarm indication. Ensure the high accuracy, high stability and high reliability of real-time online monitoring of grounding resistance value in various place.3. Contact Type On-line Earth Resistance Tester suitable for transmission line tower grounding, underground mine equipment grounding , weather lightning protection grounding, petrochemical grounding, communication base station grounding, power substation grounding , railway grounding, building warehouse grounding , electrical equipment grounding, etc. Measurement Range & Accurancy: (Note: 23℃±5℃，below 75%rh)Measurement FunctionRangeAccuracyResolutionEarth Resistance0.01Ω～20Ω±2%rdg±3dgt (auxiliary earth resistance 100Ω±5%，Voltage to earth＜10V)0.01Ω0.1Ω～200Ω±2%rdg±3dgt (auxiliary earth resistance 100Ω±5%，Voltage to earth＜10V)0.1Ω1Ω～2000Ω±2%rdg±3dgt (auxiliary earth resistance 100Ω±5%，Voltage to earth＜10V)1ΩEarth Voltage0～600V AC±2%rdg±3dgt1V Technical Parameter: FunctionDescriptionApplicationOnline monitoring of grounding resistance, grounding voltage, equipotential bonding resistance, and low value resistancePower SupplyStandard: 12V±1VDC、400mA Max; Optional: 24V±1VDCTest Methodprecision 3-wire or simple 2-wire measurement methodMeasurement MethodGround Resistance: Rated current pole method, measuring current 11mA Max，128HzGround Voltage: Average rectificationData ModeAverage valueDisplay Mode4 Digits large LCD displayMeasurement IndicationIn measurement, LCD count down indicationLCD size128mm×75mm; Display area: 124mmX67mmTester Dimension190mm×117mm×54mmMeasurement TimeVoltage to earth: about 2 times/seconds; Grounding resistance: about 30 seconds/timesMeasurement TimesAbove 10,000 timesLine VoltageMeasurement voltage to earth: AC below 600VTester InterfacePlug Terminal Block: 9-pin terminal blockData CommunicationRS485 (optional RS232)ShiftAutomatic shiftData Storage400 sets, flashes display "FULL" symbol indicate that storage fullInterval timeAutomatic monitoring interval time of setting range: 1 ~ 999 hoursData AccessData access function: display "READ" symbolOverflow IndicationOver range overflow function: display "OL" symbolPower ConsumptionStandby：25mA MaxMeasurement：400mA MaxAlarm Indicationaudible and visual alarmPower VoltageWhen power voltage lower than 10V, display low power voltage symbol, and remind to replace batteryTester Weight450gWorking Environment-10℃~40℃；below 80%rhStore Environment-20℃~60℃；below 70%rhOverload ProtectionIn measurement of ground resistance：E-P、E-C AC 280V / 3 seconds between each terminalInsulation Resistanceabove 10MΩ (500V between circuit and outside shell)Withstand VoltageAC 3700V/rms (Between the circuit and the shell)Electromagnetic characteristicsIEC61010-4-3，Wireless frequency electromagnetic field≤1V/mSuitable Safety StandardIEC61010-1、IEC1010-2-31、IEC61557-1,5、IEC60529(IP54)、Pollution 2、CAT Ⅲ 300V Packing: PackageOuter packageCartonInner packageNoneAccessoryMeter1 PCS9-pin Terminal Block1 PCSManual/Warranty Card/Certificate1 PCS
