Product Introduction
Contact resistance tester is a high-precision electronic measuring instrument, mainly used to measure the resistance of the contact surface in the circuit. The tester is made of high-reliability high-power integrated circuits and consists of a DC constant current source, a preamplifier, an A/D converter and an indicator. Its working principle is based on Ohm's law. By applying a stable current to the measured resistor, the voltage drop signal generated by the current flowing through the measured resistor is collected, and after amplification and conversion processing, the DC resistance value of the measured object is obtained.
