Description

Contact resistance increases due to contact surface oxidation, poor contact fastening and other reasons. The Test procedures require conductive contact resistance testing of various switchgear and cable connectors, the test current shall not be less than 100A. When the high current flows, the temperature of the contact point rises, which accelerates the oxidation of the contact surface and further increases the contact resistance will lead to serious accidents. Therefore, it is necessary to measure the contact resistance often or regularly.

Main Features

Wide resistance measurement range and high resolution.
High precision switching power supply, automatically adjust.
With temperature compensation function, automatically convert to 20ºC resistance.
Easy operation with a 5.0" 65K color touch screen.
Built-in high-capacity non-volatile memory for 500 sets of data.
Built-in high-speed micro thermal printer for printing measurement data.
Data can be exported through a U disk.
