Production Description

The circuit resistance tester is a high-precision, digital switch tester developed by the company according to IEC standards and the latest power executive standard DL/T845.4 - 2004 of the People's Republic of China, giving play to its technical advantages. The instrument adopts high-frequency high-power constant current switching power supply technology, and can measure micro ohmic contact resistance.

It is widely applicable to the measurement of contact resistance, loop resistance, cable wire and weld joint contact resistance of various switches and electrical appliances. The instrument has accurate measurement data and stable performance, meeting the requirements of on-site high-voltage switch maintenance of power supply departments and high-voltage switch factory loop resistance test. The output current and measurement resistance are output on the 65K true color LCD at the same time, and the measurement results can be either output voltage or stored in a USB flash disk. The power down storage can meet the data query at any time.
