WinAPEX VC4105A Digital Grounding Resistance Tester Grounding Geometer

Because the battery can not be transported, so you receive the goods do not contain batteries!Product Description:Grounding resistance tester is a professional instrument for testing grounding resistance of electrical equipment. The circuit, structure and technology of traditional grounding resistance tester have been improved. With beautiful and practical fashionable style, it has more complete functions, higher accuracy, more convenient and reliable operation, dust-proof and moisture-proof structure, and is more suitable for field use. It can be used to measure the grounding resistance of various power systems, power equipment, lightning protection equipment and other grounding systems, as well as AC voltage. Product content: 1. Grounding Resistance Table 1 2. One canvas bag 3. Grounding steel brazing 2 4. Auxiliary test set (including red 15 meters, yellow 10 meters, green 5 meters) 5. A set of simple test lines (including red 1.6m-strip and green 1.6m-strip) 6. Use Instructions 1 7.

Product Qualification Certificate 1 Safety matters This series of instruments are designed in accordance with IEC1010 (Safety Standard promulgated by the International Electrotechnical Commission). Please read Safety Notes before using them. Matters of interest. 1. Read the instructions carefully before using the grounding resistance meter. One 2. If the surface of the grounding resistance meter or measuring line is damaged, 3. Do not touch live DC60V, AC36V RMS or above conductors to avoid electric shock. This voltage has reached the standard of electric shock. 4. Before measuring resistance, it must be completely isolated from the power supply circuit to ensure accurate reading and personal safety. 5. Instruments should not be stored at high temperature to avoid direct sunlight to affect the life of LCD. 6. Battery energy is insufficient. Symbolic "" display, please replace the battery in time. Batteries should be removed in time for long-term storage. No damage to instrument by battery liquid. 7. When measuring bare wires, be very careful. 8. When the external adapter is powered, the internal battery will be disconnected, and the battery can not be charged at this time. Note: Please select (2) Power supply mode. 9. Grounding resistance test requirements: A. AC working grounding, grounding resistance should not be greater than 4_;;; B. Grounding resistance should not be greater than 4 when working safely. C. DC working grounding, grounding resistance should be determined according to the specific requirements of the computer system; D. The grounding resistance of lightning protection ground should not be greater than 10. E. The grounding resistance should not be greater than 1 for shielding system when combined grounding is adopted.
