Safety rules and precautions
Thank you for purchasing our Handheld DC resistance tester. In order to avoid
possible electric shock or personal injury before your first use of this tester, please be
sure to read and strictly observe the safety rules and precautions set out in this manual.
Special attention should be paid to safety when using this instrument under any
circumstances.
² This instrument according to IEC61010 safety specifications for design,
production, inspection.
² Special attention should be paid to safety when using this instrument under any
circumstances.
² When measuring, please do not use the high frequency signal generator such as
mobile phone near the instrument, so as not to cause error.
² Pay attention to the label and symbol of the instrument body.
² Before use, make sure that the instrument and accessories are in good condition and
the instrument and test line insulation layer are not damaged, exposed or broken before
use.
² During the measurement, do not contact the bare conductor and the circuit being
measured.
² Make sure the connector plugs of the wires are tightly inserted into the instrument
interface.
² Do not measure in inflammable place, spark may cause explosion.
² When the instrument is in use, the casing or test line is broken and the metal is
exposed, please stop using it.

Introduction
Handheld DC resistance tester, also known as transformer DC resistance tester, DC
resistance rapid tester, grounding conductivity tester, adopts microprocessor technology,
four-wire test, safe, precise and reliable.Is mainly used for measurement of transformer
winding resistance, transformer winding resistance, ground down lead conduction testing,
the wire resistance of the cable, switch, socket, relay contact resistance, winding, motor,
shell and equipment, lightning protection zone, ground beam, structure, rack, steel, pipe,
Windows, fence, radiator, pipeline connection between objects such as metal
components resistance test.It is widely used in telecommunication, electric power,
meteorology, machine room, oil field, electric power distribution line, tower transmission

line, gas station, factory grounding grid, lightning rod and so on.
Handheld DC resistance tester is composed of a host, monitoring software, test line
and communication line.Host handheld portable design is convenient for field application,
with charging function without on-site power search, full-color large LCD display, clear at
a glance, easy to use touch screen operation, port overload protection function.Large
capacity storage 500 groups of data, resistance measurement range: 10.0 u Ω 50.00 K Ω,
measuring accuracy: ±0.2%FS±10dgt.The upper computer software has the functions of
reading, consulting, saving and reporting historical data.
