Lightning Protection Element Tester is suitable for testing the DC parameters of over-voltage protection components such as zinc oxide surge arresters (varistor) cermet two three-electrode discharge tubes and vacuum lightning arresters. Product nicknameï¼?Lightning Protection Element Tester Lightning Protection Component Tester Lightning Protection Element Tester Lightning Protection Element Tester 1 Lightning Protection Element Tester is suitable for the measurement of DC parameters of zinc oxide surge arresters (varistor) cermet two three-electrode discharge tube vacuum lightning protection tube and other overvoltage protection components. It can also be used for voltage regulation constant current power supply and used in other aspects. 2 with high voltage short circuit protection over current protection high pressure preset range adjustment and other functions high pressure self-release time is less than 0.5 seconds. 3 with self-test function. 4. The measurement data is displayed by three-and-a-half LCD digits with high accuracy and good reliability. 5. When measuring the range can be preset and an audible indication is given to the over-range test during the measurement process which is suitable for device grouping and inspection. 6 select continuous measurement you can carry out uninterrupted testing of batch samples. 7 the Lightning Protection Element Testerpanel is simple and easy to operate. 8 light weight easy to carry.
