Description
Double clamp ground resistance tester
Product overview
KDCR series clamp type earth resistance meter is widely used in power, telecommunication, meteorology, oil field, construction and industrial electrical equipment, such as earth resistance measurement, loop resistance measurement.
When measuring the ground system with a loop, it is not necessary to disconnect the ground lead line, no auxiliary electrode is required, safe and fast. It can measure the ground fault that cannot be measured by the traditional method, and can be applied to the occasions that cannot be measured by the traditional method, because the KDCR series clamp ground resistance meter measures the comprehensive value of the grounding resistance and the grounding lead resistance.

Product characteristics
1, with USB-RS232 interface clamp ground resistance meter, data upload computer, software monitoring, dynamic display.
2, break through the long time of boot self-test wait, boot immediately into the test.
3. Break through the relay self-test method, eliminate the relay, and adopt intelligent algorithm and digital integrated processing technology.
4, break through the bulky characteristics of the old product, more in line with the characteristics of handheld instruments.
5, the appearance design panel 6-key operation, performance through.
6, increased the audible and visual alarm function, “dud-dud-dud-dud-” alarm sound.
7, increased the interference signal recognition, indicating function, “dud-dud-dud-dud-” prompt tone, NOISE symbol flashing
8. Add storage data: 99 groups.
9, the resistance range is wider: 0.01Ω-1200Ω
10, leakage current detection resolution is higher: 0.05mA
11, lower power consumption: the maximum starting current does not exceed 50mA.
12, the test speed is faster: 0.5 seconds/time
13, stronger anti-interference ability; Higher test stability.
