Aplab Precision LCR Meter Model 4300R is a new generation of impedance test equipment with high accuracy, wide measurement range and six digits resolution. Being featured with test frequency up to 300kHz, test voltage of 5mV ~ 2V, built-in -5V ~ 5V DC bias and -10V~10V DC voltage source output, it can meet all requirements for measuring components and materials and provide guarantees for production line quality assurance, incoming inspection and laboratory precision measurements. The Handler, RS232C and GPIB interfaces as well as improved command system provided by the instrument make it easier to build the test system.
