Product Details

I． Introduction

XZTZ3060 Digital DC low resistance meter, also known as micro-ohmmeter, ohmmeter, equipotential tester, using the microprocessor technology, four-wire test, safety, precision and reliability.Mainly used to measure the wire resistance of cables, the contact resistance of switches, connectors, relays, the resistance of coils, motors, transformer windings, and equipment enclosures, lightning protection belts, ground beams, structures, cabinets, steel bars, water pipes, windows, guardrails, and heat dissipation Connection resistance test between metal components of objects such as devices, assembly lines, etc.

It is widely used in telecommunications, electric power, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding grids, lightning rods, etc.

XZTZ3060 digital DC low resistance meter is composed of host, monitoring software, test line, communication line, etc. The large-screen LCD display of the main unit is clear at a glance, and the port overload prevention function prevents the instrument from being burned out by misoperation.Store 500 sets of data, resistance measurement range: 0.001mΩ~ 300.0KΩ. The upper computer software has functions such as historical data reading, consulting, saving, and reporting.
