The 6425 is designed to give fast and accurate readout of component values, easy sorting of resistors, capacitors and inductors, detailed analysis of networks, and rapid monitoring of changing values. An extended measurement range, wide choice of operating frequency and adjustable drive level make the Analyzer a powerful tool in design laboratories, goods inwards sections, test departments and in connection with chemical and physical research work. A cathode-ray tube is used to present clear and unambiguous results in numeric and graphic form, to display warning and other messages and, under software control, it automatically labels a set of ten 'soft' keys to show the parameter selection available for each mode of operation. All key settings are retained in non-volatile memory. Because there are no variable controls requiring user adjustment, and values can be read directly in the terms required, confidence in the validity of results is maximized for all levels of operator skill.
