I. Safety rules and precautions
Thank you for purchasing our company's clamp-on grounding
resistance tester. Before you use the instrument for the first time,
in order to avoid possible electric shock or personal injury,
please be sure to: read carefully and strictly abide by the safety
rules and precautions listed in this manual .
In any case, special attention should be paid to safety when
using this instrument.
♦The instrument is designed, produced and inspected
according to IEC61010 safety specifications.
♦ In any case, pay special attention to safety when using this
instrument.
♦During measurement, do not use high-frequency signal
generators such as mobile phones near the instrument to avoid
errors.
♦Pay attention to the text and symbols on the label of the
instrument body.
♦Make sure the instrument and accessories are in good
condition before use.
♦Before starting the machine, squeeze the trigger once or
twice to ensure that the jaws are well closed.
♦Do not measure in flammable places, sparks may cause
4
explosion.
♦When the machine is turned on, do not hold the trigger or
clamp any wires.
♦The object to be measured can only be clamped after the
“OL Ω” symbol is displayed after it is turned on normally.
♦ Do not place and store the meter for a long time in places
with high temperature and humidity, condensation and direct
sunlight.
♦ When replacing the battery of the meter, please make sure
that the meter is turned off.
♦The meter displays the low battery voltage symbol “ ”,
the battery should be replaced in time, otherwise it will lead to
ground error.
♦ The contact surface of the jaws must be kept clean and
cannot be wiped with corrosives and rough objects.
♦ When opening the trigger, avoid shock to the clamp meter,
especially the jaw interface.
♦When the clamp meter is measuring resistance, the clamp
head will make a slight noise, which is normal.
Pay attention to the "beep-beep-beep--" sound to distinguish
the alarm.
♦Pay attention to the measurement range and operating
5
environment specified by this instrument.
♦The current of the measuring lead should not exceed the
upper limit of the clamp meter.
♦The use, disassembly, calibration and maintenance of this
instrument must be operated by authorized personnel.
♦Due to the reasons of this instrument, if it is dangerous to
continue using it, you should stop using it immediately and seal
it up immediately.
♦Deposits shall be processed by authorized institutions.
♦The “ ” safety warning sign in the instrument and manual,
the user must strictly follow the instructions in this manual
for safe operation.
II. Introduction
Clamp ground resistance tester, also known as loop resistance
tester, is used to test ground resistance. This instrument uses a
new black luxury screen design, the resistance current is
displayed on the same screen, and it also has functions such as
data storage, data review, alarm, and automatic shutdown. The
whole machine is beautiful and high-grade, with a wide range,
high resolution, convenient operation, convenient carrying,
accurate, reliable, stable performance and strong
anti-interference ability. Moreover, it has a shock-proof,
6
dust-proof and moisture-proof structure. It is a common 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 grounding resistance of various telecommunications,
electric power, meteorology, computer room, oil field, power
distribution lines, tower transmission lines, gas stations, factory
grounding grids, lightning rods, etc.
The clamp ground resistance tester is controlled by a
microprocessor and can accurately detect ground resistance. It
uses fast filtering techniques to minimize interference.
Simultaneous data storage and data upload functions.
