Introduction
UHV-H200A Portable Micro Ohmmeter measures up to the latest power system standards--DL/T845.4-2004 designed for measuring loop resistance of Switching Control Equipment using High-frequency switching power supply technology and digital circuit technology. Test current of the Tester is DC-100mA
Or DC-200mA which is recommended in the national standards. The tester can measure the loop resistance at those values and display results indigital. It is high precision and good stability and can meet most power systems' requirements in onsite high-voltage switches maintenance and high-voltage switches factory loop resistance measurement. (It performances accurately and stably)
Functions
UHV-H200A Portable Micro Ohmmeter is suitable for measuring loop resistance of high-voltage switches in high-precision. It also applies on other test occasions that need high current and micro resistivity.
(1) High current: For latest power supply technology, the tester can continuously output high current which overcomes the weakness of instantaneous current produced by pulsed power. It can effectively breakdown/puncture the oxide layer of the switches and then get precise results.
(2) Strong anti-interference ability: The last number of test data will stably show in the LCD screen only with ±1 error even in strong Interference situation.
(3) Long service life: All the precise resistances used in the tester can reduce the temperature's impact on the measurement results and military connectors can enhance vibration resistance.
(4) Convenience: Small size, light weight.
