Product Overview
The handheld loop resistance tester (Contact resistance tester/Micro-ohmmeter) is widely used for measuring the contact resistance of various switches and electrical appliances, as well as the contact resistance of cables, wires, and welds, meeting the requirements of the power sector for contact resistance testing.
Advantage
◆ Intelligent synchronous rectification power conversion circuit up to 500KHz is adopted to output 100A50A two-gear current.
◆ Digital management of power supply batteries, with residual power display, residual power alarm, overcurrent protection, and other functions.
◆ It has power on data storage and a perpetual calendar, which can store 1000 sets of test data and store test time in real time.
◆ It has a USB flash disk interface and printer expansion interface, and optional external micro printer can print test data in real time.
◆ High resolution 65K true color 7-inch touch screen, Chinese and English interface switching, high brightness, and clear display under strong light.
◆ Optional Bluetooth module, which can connect Android system phones and tablet devices to achieve intelligent management and operation.
◆ Internal battery power supply or power adapter power supply of the sampling instrument.
◆ Four terminal method is adopted for wiring, and the current line and voltage line are separated by four wires and four clamps to eliminate wiring interference and errors.
