Introduction
The LCR 400 Precision Bridge provides a fast, convenient and accurate means of measuring the
inductance, capacitance, resistance, D and Q of components with a basic accuracy of 0.1%. The
major and minor parameters of the component are displayed simultaneously.
The microprocessor controlled unit provides fully automatic mode and range selection for a wide
range of components. Control is by front panel keyboard or by RS232 link to a PC which can be
used to set up all measurement functions.
The LCR400 can be programmed to sort a range of components into bins according to value.
Multiple bins can be set to sort different tolerances of the same value or different values.
Up to nine measurement set-ups can be stored in the instrument in non-volatile memory and
called up for re-use with a few keystrokes.
Connections to the components are made via the built in four–terminal test fixture or plug–in axial
adaptor providing true contact resistance free measurements for low impedance components.
The capacitance (up to 100pf) introduced by an external test fixture can be cancelled out
permitting high impedance measurements to be made with confidence.
