Feature:1. ONLINE MEASURING: Non contact online measurement does not affect the thunder protection grounding effect and the normal operation of the facility, and uses GPRS wireless communication to transmit data, realize remote online monitoring.2. WIDE APPLICATION: The resistance range is 0.01-100, with a wide range of applications, a single measurement time of about 0.5 seconds, has high efficiency and durability.3. HIGH PERFORMANCE: The built in sensor and circuit board of the detector are completely closed to ensure high accuracy, stability and reliability of long term online monitoring indoors and outdoors.4. LCD DISPLAY: The test value is directly displayed by LCD, and the alarm threshold can also be set through the detector, with sound and light alarm indication, no need to set up a network.5. MULTIPLE USAGES: Suitable for transmission line tower grounding, petrochemical, communication, distribution station grounding, building warehouse, electrical equipment, etc.Specification:Item Type: Online Ground TesterModel: ETCR2800KCMaterial: PVCUses: Suitable for transmission line tower grounding; meteorological thunder protection grounding; petrochemical grounding; communication grounding; substation grounding; railway facilities grounding; building warehouse grounding; metal loop resistance; electrical equipment grounding, etc.Functions: Online monitoring of loop grounding resistance, online monitoring of metal loop connection resistance, monitoring of grounding conditionCT Structure: Open Close TypeResistance Range: 0.01-100Resolution: 0.001Accuracy: 2%rdg3dgt (205, below 70%RH)Overflow Indication: When the test value is greater than 100, the LCD displays the OL symbolAlarm Indication: Detector sound and light alarm and LCD displayAlarm Settings: Detector panel key settings, background settingsWorking Temperature and Humidity: -20-55; 20%RH-90%RHTemperature and Humidity Error: No more than 5%Shifting: Automatic shiftingExternal Magnetic Field: <40A/mExternal Electric Field: <1V/mSingle Measurement Time: About 0.5 secondsPower Consumption: 12VDC 150mA Maximum.Package List:1 x Tester1 x Plug Cable1 x Antenna2 x Hangers4 x Hex Screws1 x Hex WrenchNote:1. For a single point grounding system, it is necessary to add an auxiliary ground pole to form a loop, and then install the detector.2. Pay attention to the measurement range and operating environment specified by the detector.3. The detector is divided into an open close structure and a closed loop structure. The front and rear seats of the open close structure detector are paired at the factory and cannot be exchanged with the front and rear seats of other detectors, otherwise the test accuracy will be seriously affected. When installing, please check whether the body codes of the front and rear seats are the same.4. Please keep the joint surface of the upper and lower seats clean when installing, and tighten the screws of the upper and lower seats when fixing them.5. When used in dangerous places, the external power supply must be connected to the detector through the safety barrier, and the safety barrier should be placed in the non hazardous area.
