|Xtester-Xtester-ETCR2000A+ Clamp Earth Resistance Tester is our company's technology research and development team on technical quality of the pursuit of excellence, through continuous innovation to improve, upgrade with the old product. Its performance is mainly reflected in:
Breakthrough in self-test the boot a long time to waiting, start immediately into the test.
Breakthrough relay self-test mode, using the most advanced processing algorithms and digital integration technology.
Breakthrough the old product too heavy issues, more in line with characteristics of hand-held devices.
New design, panel operation with 6 buttons, better performance.
Increase sound and light alarm function, with "beep-beep-beep” alarm sound.
Increase the interference signal recognition indicator function, with "beep-beep-beep” indicator.
Measurement range: 0.01Ω-1200Ω
Stored data 99 Units. Lower power consumption, Maximum operating current less than 50mA.
Xtester-Xtester-ETCR2000A+ Clamp Earth Resistance Tester is widely used in the grounding resistance measurement of the power, telecommunications, meteorology, oilfield, construction and the industrial and electrical equipment. In the measurement of a grounding system with loop, does not require breaking down the grounding down lead, and no need the auxiliary electrode. It is safe, fast and simple in use. The tester can measure ground faults which cannot be measured by traditional methods. It can be used in applications where traditional methods cannot be measured, because the Xtester-ETCR series clamp grounding resistance meter measures the combined value of grounding body resistance and grounding lead resistance.

(Base on the formula: R=E/I)
(R1 is the measured earth resistance;
R0 is the equivalent resistance of the grounding resistor in parallel)
The RA is the measured grounding object, connecting RA
and RB (which is the nearly grounding object like as water
pipe or building) with one wire, the tester will test and indicate the concatenation resistance value of the ground
resistance and the test line resistance.
(RT is the tested value, RL is the test line resistance value)
(1).Connect the RA and RB with a test line; use the Meter to get the first reading R1;
(2).Connect the RB and RC with a test line; use the Meter to get the first reading R2;
(3).Connect the RA and RC with a test line; use the Meter to get the first reading R3.
In the above three steps, the reading measured in each step is the value of the two series grounding resistance. In this way, we can easily calculate the value of each grounding resistance,According to the reading value of R1,R2,R3:
R1=RA+RB; R2=RB+RC; R3=RA+RC
As the reference points, the grounding resistance values of the other two grounding bodies
RB and RC are:
The machine room of telecommunication system normally in the upper deck of the
building. It is hard to use the meg-ohm meter to measure. However, Xtester-ETCR Clamp
meters are very convenient to test.
Xtester-ETCR series clamp meter can use to test the situation of contact and connect of circuit.
With the help of one test line, it can be used to test the connect situation of equipment
in station and the grounding system. Single point grounding measurement is allowed for
the measurement of grounding resistance.
If the earth poles of the building are independent of each other, the earth resistance can
be measured by clamp to testing any of the earth poles, and the earth resistance can also
be measured by clamp the building roof lightning arrester.When the measured value is
less than the allowable value, the earth electrode is qualified.If the measurement value
of the clamp meter is larger than the allowable value, please use single earth point method
