Audited Supplier KD2678 32A/70A ground resistance tester/Ground resistance meter meters
Product overview
KD2678 ground resistance tester is used to measure the internal ground resistance of electrical equipment, which reflects the (contact) resistance between the exposed conductive part of the electrical equipment and the total ground terminal of the electrical equipment. In order to eliminate the impact of contact resistance on the test, the 4-end measurement method is used, that is, the current is added between the exposed conductive part of the electrical appliance to be tested and the total ground terminal (generally about 25A), and then the voltage at both ends is measured to calculate the resistance value.
KD2678 grounding resistance tester is designed in accordance with GB, IEC, ISO, BS, UL, JIS and other international and domestic safety standards. The indicator of grounding resistance is one of the important indicators to measure the safety performance of various electrical equipment. It is in...
The resistance of the grounding circuit is measured at high currents (10A,25A or 70A), and the grounding circuit is also tested to withstand high current indicators to avoid personal injury when the insulation is decreased (or damaged). This tester is developed and produced to meet the above requirements to provide high performance testing instruments for production workshops and experimental departments.
This instrument does not require high power supply voltage, high measurement accuracy, fast speed, easy to use, especially suitable for high-demand laboratory and automatic detection line use. The new line break alarm function (that is, open circuit alarm) can be very convenient to know whether the instrument is working in the normal test state, and users can choose whether to need this function according to actual needs.
The instrument adopts 3 1/2 digit digital display, easy reading, optimized design, the whole machine has high reliability and stability. This tester is suitable for different national standards: such as in line with GB4706.1-1998 household and similar electrical appliances safety standards in the general requirements of the provisions of the relevant provisions.

Product characteristics
1, open the alarm
The instrument can detect the ground circuit of the measured object is open or the test clip is not connected to the instrument or the test clip is not connected to the measured object, and can choose whether to issue sound and light alarm according to actual needs.
2, overcurrent alarm
This instrument has an overcurrent alarm function, when the loop current exceeds 32.5A (32A model), 72A(70A model), the instrument emits an audible and optical alarm of overcurrent, the overcurrent lamp continues to light, the buzzer continues to sound, press the "reset" button, you can cancel the alarm state, and the "current adjustment" knob is turned counterclockwise smaller for the next measurement.
3, the resistance alarm value is adjustable from 0 to 600mΩ
When the preset key is pressed, the 200m /600mΩ file pops up, and the preset value can be set from 0 to 210.0mΩ. When 200mΩ/600mΩ is pressed, the preset value can be set from 0 to 610mΩ.
4, the test time in 0 ~ 999S arbitrary setting
Users can set the test time according to their own needs.
5, continuous test function
In the case of zero setup time, the tester can be continuously tested.
6, there is no need to set the alarm value in the case of current output
The instrument does not need to preset the alarm value when there is a current output. Can be set with an open circuit.
7. External control
This machine is equipped with "PLC" interface, and PLC can form a pipeline test system. (optional)
