II ． Introduction

Digital Micro Ohm 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.

Digital Micro Ohm 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.
