The 4262A LCR meter for component measurements uses a microprocessor to automate procedures, thus increasing the capabilities of the meter without incurring significantly greater costs. To measure the value of a passive component with this instrument, it is only necessary to select the measurement function and loss parameter - resistance (R), capacitance (C), or inductance (L), and dissipation factor (D) or quality factor (Q) - select the appropriate test frequency, and connect the component to the test terminals. The instrument automatically switches to the correct measurement range, selects the preferred circuit mode, and presents results on the 3½ digit displays in about 250 ms without any time-consuming balancing adjustments. The user, however, can have full manual control of the instrument at any time simply by pressing the appropriate front-panel pushbuttons.
