The instrument is small in size, light in weight, beautiful in appearance and easy to operate. The test current and resistance values are displayed in real time with LED digital panel, which is clear, accurate and intuitive. The test current can be adjusted arbitrarily from 0 to 30A according to the different needs of users, and the test time can be set continuously from 1 to 99s. When the resistance value of the measured object exceeds the user's setting value (0-510 m_can arbitrarily set the alarm point), the instrument has sound and light alarm function, and has over current (AC 30A) protection function and sound alarm. Its advanced open-circuit alarm function enables users to effectively avoid false detection and missed detection. The instrument can widely meet different user testing needs.
