Ground resistance tester adopts dual power supply mode
Digital grounding resistance tester, also known as three-wire grounding resistance tester, grounding resistance meter, etc. is a common instrument for inspection and measurement of grounding resistance commonly used instruments, using a large LCD grey and white screen backlit display and microprocessor technology, to meet the two-wire, three-wire test resistance requirements. Applicable to telecommunications, electric power, meteorology, engine room, oilfield, power distribution lines, tower transmission lines, petrol stations, factories, grounding network, lightning rods and so on. Instrument testing precision, fast, simple, stable and reliable features.
Digital grounding resistance tester controlled by a microprocessor, can automatically detect the connection status of each interface and ground network interference voltage, interference frequency, and with the test auxiliary grounding pole resistance value function, the same screen display the measured grounding and auxiliary grounding resistance value at a glance. Simultaneous storage of 500 groups of data, resistance measurement range: 0.01 Ω ~ 3000 Ω, grounding voltage range: 0 ~ 100 V. Can be monitored through the monitoring software to monitor data online, USB data upload to the PC and has a numerical value to maintain and intelligent alarm prompts and other unique features.
Digital grounding resistance tester consists of host, monitoring software, test cable, USB cable, grounding pin, with historical data reading, access, save, report, print and other functions.
Features:
Dipole method to measure DC resistance and AC resistance.
Three-pole method and four-pole method measure grounding resistance.
Direct measurement of soil resistivity by four-pole method.
Current clamp selective method of measurement, without disconnecting the ground connection.
Dual clamp head without auxiliary pole method, fast measurement of ground loop resistance.
Automatic Frequency Control (AFC), can automatically identify interference and select the appropriate measurement frequency to minimise the impact of interference. Selectable frequency of 94Hz, 105Hz, 111Hz, 128Hz four.
Can automatically measure the interference voltage and leakage current.
With measurement data storage function, can store 100 groups of measurement data, and can be uploaded to the PC
Display and analyse, output test report.
Limit value alarm function.
Automatic shutdown function.
Clock display function.
Dual power supply, dry battery or rechargeable battery can be selected.
