|MEWOI4700, MEWOI4700C intelligent Equipotential&DC Resistance Tester, also known as DC low resistance tester, DC resistance tester, Ohm meter, micro resistance meter,contact resistance tester etc., adopting four line precision test method, accurate and reliable. It is a special instrument for measuring the quality of equipotential bonding between the metal components of a building (lightning belt, ground beam, structure, protection, floor reinforcement, water pipe, radiator, toilet, door and window, balcony, kitchen and other objects). It can also measure the resistance of the connecting conductors between various electrical equipment and ground grid, It can also measure the contact resistance of circuit breakers, switches and sockets, and various coil resistors, shunt resistors, metal riveting resistors of vehicle and ship aircraft, resistance of welding joints, battery parallel connection resistance, distributor busbar and wire contact resistance, etc. It is widely used in building quality inspection station, supervision company, construction unit, lightning protection company, electric power department, ship locomotive factory, etc.|
The instrument also has alarm function, clock function, can test wire length, first measure the wire resistance of a standard length, test the resistance of the whole wire, and calculate the length of the wire through the resistance of the two times’ test.
MEWOI4700, MEWOI4700C intelligent equipotential tester consists of host, monitoring software, test line, charger, USB communication line and so on. The host has super LCD display, with backlight and bar chart instructions, can store 400 sets data. The monitoring software has the functions of reading, accessing, saving, reporting and printing historical data.
