The Earth Resistance tester is applicable to the testing of the earth resistance of the power supply wires, distribution wires inside a room, electrical equipment or appliance, which can done in two measurement modes: Bi-poles or Tri-poles, and it also can be used to measure the earth voltage. Constant Current Conversion is used for the measurement of earth resistance, with the frequency of the testing current about 800HZ and the size about 3mA.
The earth resistance tester is six 1.5V AA batteries with multiple user select-able test frequencies. Measurements can be executed as 2, 3 and 4-pole testing.
The earth resistance tester is rated IP54 and is designed to meet stringent safety standards.
One-button operation guarantees simplicity of use for your project. A large rotary switch allows selecting between 2, 3 or 4-pole testing.
Coming with a large, clear and easy-to-read LCD display the earth resistance tester is suited to various site conditions of earth testing and for use outdoors in addition to this warning indicator prevents test failure.
The earth resistance tester includes a current measuring function for Attached Rod Technique (ART) testing capabilities. With this added function, on-site earthlings’ can be tested separately without having to remove the utility connection.
The earth resistance tester also provides stakeless testing capability. This method allows the operator to use the instrument like a clamp-on earth tester or measurements without auxiliary earth stakes.
The earth resistance tester automatically checks the connection and conditions of the P spike, C spike, and also the level of ground noise, indicating the status on the display. It also includes a voltmeter for measurement of ground voltage. Earth resistance testers are of Germany standard
