INTRODUCTION

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.

Measurement Principle

Measure the loop resistance

(Base on the formula: R=E/I)

Measure the grounding loop resistance system

(R1 is the measured earth resistance;

R0 is the equivalent resistance of the grounding resistor in parallel)

Measurement Method

Two earth point measurement method

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=RA+RB+RL

(RT is the tested value, RL is the test line resistance value)

Three earth point measurement method

(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

Then: RA=(R1+R3-R2)/2

As the reference points, the grounding resistance values of the other two grounding bodies

RB and RC are:

RB=R1-RA; RC=R3-RA

Field Application

The application of machine room earth resistance measurement

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.

The application of substation earth resistance measurement

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.

The application of building lightning protection grounding system measurement

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

to measurement.
