Product Main Function
1. Measure the grounding impedance or resistance of large grounding devices, measure the conduction impedance or resistance between grounding devices, measure the soil resistivity, and measure the simple step voltage.
2. Impedance Measurement Range :0O~200O
3. Soil Resistivity Measurement Range :0Om~125KOm
   ETCR3300B Large-Scale Grounding Grid Earth Resistance Tester is a power frequency grounding resistance, grounding resistance, soil resistivity, and simple step voltage tester carefully developed by our company for substation grounding grids, power plants, microwave stations, and communication base stations. The instrument uses a touch color screen to operate particularly convenient and simple, click the "help" button to operate prompts at a glance, the instrument uses a new type of variable frequency AC power supply and microcomputer processing control and signal processing measures, a good solution to the problem of anti-interference in the test process, simplified The test operation process improves the accuracy and accuracy of the test results and greatly reduces the labor intensity and test costs of the test personnel. The instrument adopts super-strong automatic frequency conversion anti-interference technology, and with 400V/5A high-power output, it can accurately measure the data under the power frequency 50Hz in a strong interference environment. It is suitable for testing power frequency characteristic parameters such as power frequency grounding impedance, ground resistance, soil resistivity, step voltage and so on of various grounding devices.
  The instrument is based on "JJG984-2004 Grounding Continuity Verification Regulations Resistance Tester", "DL/T475-2006 Grounding Device Characteristic Parameter Measurement Guidelines", "DL/T845.2-2004 Resistance Measuring Device General Technical Conditions Part II: Engineering Frequency grounding resistance tester" manufacturing.
Product features
1. With 5 inch touch colorful screen, easy to operation. With the test function of soil resisitivity and simple step voltage.
2. Supports Bluetooth communication for Android system. After installing the APP, can test or view the test results on the mobile terminal.
3. The instrument case is made of high strength engineering plastic, which is resistant to strong impact, abrasion, aging, and protection grade is IP65..
4. 400V, 5A high power output that can ignore the power frequency interference of the substation.
5. Equipped with built-in printer, printing test results on site. With bluetooth communication function, support Android system, more convenient to view uploaded test records. and with USB interface
