KDDQ2571BV Ground Resistance Tester

　　It can be used to measure the ground resistance of various grounding devices. The four-wire method can avoid the influence of lead resistance. The input distance can be directly measured and calculated to display the soil resistivity. It can also measure the resistance value and ground voltage of low-resistance conductors.

　　Features

• 　　A single tester integrates grounding resistance, ground voltage, soil resistivity measurement and other functions, greatly improving the efficiency of field testing, built-in analog and digital filters, and strong anti-interference ability. 100 sets of test data can be saved;
• 　　dot matrix LCD display, easy to read, rich auxiliary information display, including auxiliary grounding resistance, ground interference voltage, etc.;
• 　　Intelligent identification of the interference voltage, when the interference is too large, the test will be stopped and a reminder message will be displayed, supporting two modes of single measurement and continuous measurement;
• 　　3-pole/4-pole method ground resistance maximum test current 20mA, maximum range 2kΩ, maximum resistance to 10V interference voltage;
• 　　Power frequency voltage test can measure up to 250V voltage;
• 　　The battery capacity is 14.8V/3Ah, it can be used continuously for 8 hours, and it can be directly charged with 220V city power, which is more convenient to use;
• 　　has perfect protection function, high reliability;
• 　　has a shock-proof, dust-proof and moisture-proof structure to adapt to harsh working environments.
