Ⅰ. Safety Rules and Precautions
Thank you for purchasing our company's clamp grounding
resistance tester. Before using the instrument for the first time,
in order to avoid possible electric shock or personal injury, please
be sure to: read and strictly observe the safety rules and
precautions listed in this manual.
In any case, use this instrument should pay special attention to
safety
The instrument is designed, produced and inspected
according to IEC61010 safety specifications.
In any case, the use of this instrument should pay special
attention to safety.
When measuring, high-frequency signal generators such as
mobile phones should not be used next to the meter to avoid
errors.
Pay attention to the text and symbols on the body of the
instrument.
Before use, make sure that the instrument and accessories
are in good condition before use.
Before starting the machine, press the trigger once or twice to
ensure that the jaws are closed properly.
Do not measure in a flammable place. Sparks may cause an
explosion.
3
Do not withhold the trigger and do not clamp any
wires when turning on the meter
After the power is turned on normally, the "OL Ω" symbol is
displayed, and the measured object can be clamped.
Do not place and store the instrument for a long period of time
under conditions of high temperature, humidity, condensation,
and direct sunlight.
When replacing the battery with the meter, make sure the
meter is turned off.
The instrument displays the battery voltage low symbol
“”, should replace the battery in time, otherwise it will
lead to ground error.
The jaw contact surfaces must be kept clean and cannot be
wiped with corrosives and rough objects.
When opening the trigger, avoid the impact of the clamp,
especially the jaw joint.
When the clamp meter measures the resistance, the clamp
head will make a slight noise, which is normal. Note the
“deep-beep-beep--” sound that distinguishes the alarm.
Pay attention to the measuring range and use environment
specified by this instrument.
Do not measure the lead current above the upper limit of the
clamp meter.
The use, disassembly, calibration and maintenance of this
instrument must be performed by authorized personnel.
4
Because of the reason of this instrument, if it is dangerous to
continue using it, it should be immediately stopped and sealed
immediately, and it should be handled by a qualified
organization.
The " " safety warning sign in the instrument and manual
must be operated strictly in accordance with the contents of
this manual.
Ⅱ. Brief Introduction
Clamp ground resistance tester, also known as loop
resistance tester, is used to test grounding resistance. The
instrument uses a new black luxury screen design, resistance
display in the screen, data storage, data access, alarm, automatic
shutdown and other functions. The machine is beautiful and
upscale, has a wide range, high resolution, convenient operation,
easy to carry, accurate, reliable, stable performance, strong
anti-interference ability. Moreover, it has a shockproof, dustproof,
moisture-proof structure and is a commonly used and
indispensable instrument for telecommunications, electricity,
meteorology, computer rooms, oil fields, electromechanical
installation and maintenance, and industrial enterprises that use
electricity as industrial power or energy. It is suitable for measuring
various grounding resistances such as telecommunications,
electricity, meteorology, computer rooms, oil fields, power

distribution lines, transmission lines of iron towers, gas stations,
factory grounding networks, and lightning rods.
The clamp ground resistance tester is controlled by the
microprocessor and can accurately detect the ground resistance. It
uses a fast filtering technique to minimize interference.At the same
time data storage and data upload functions
