please be sure to:
——Read this user manual in detail.
——Strictly follow the safety rules and precautions listed in this manual.
In any case, special attention should be paid to safety when using this tester.
Can't to measure live objects. Before measuring, make sure that the measured resistance or metal body is
not charged, otherwise there is a danger of burning the instrument.
The battery low voltage symbol shows, please charge it in time, 5-8 hours per charge.
If the meter is left unused for a long time, please charge the battery every 1-2 months.
Please stop using the meter when the test wire is broken and the metal is exposed.
Do not place or store the tester for a long time in a place with high temperature and humidity,
condensation and direct sunlight.

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.
