Functional Features
◆The whole machine is controlled by a high-speed single-chip microcomputer, with a high degree of automation and easy operation.
◆The instrument adopts a new power supply technology, with multiple current gears and a wide measurement range, which is suitable for DC resistance measurement of large and medium-sized transformers.
◆The protection function is perfect, which can reliably protect the impact of the back electromotive force on the instrument, and the performance is more reliable.
◆It has an audible discharge alarm, clear discharge indication, and reduces misoperation. Fast response speed.
◆Intelligent power management technology, the instrument always works in a low power state, effectively saving energy and reducing heat. 65K true color LCD with ultra-small pixels of 320X240 dot matrix.
◆The instrument comes with a perpetual calendar clock and power-off storage, which can store 1,000 sets of test data and can be checked at any time.
◆The instrument is equipped with RS232 and USB interfaces, which can communicate with computers and store U disks.
◆Equipped with panel-type micro printer, which can print the measurement results in Chinese.
