SD2002/5 type digital ohmmeterDetailed product description：

SD2002/4 and SD2002/5 digital ohmmeters are portable universal digital instruments used for measuring resistance. It is composed of a low drift amplifier, a constant current source, an integrated A/D converter, and a single-chip microcomputer, and displays the resistance measurement results with a 4 1/2 bit LED. Instruments have the characteristics of high measurement accuracy, wide measurement range, stable performance, and easy operation, and are suitable for use as tools for testing resistance parameters in factories, mines, enterprises, laboratories, and scientific research departments. SD2002/5 with RS232 interface.
