Description of the LCR Meter and Its Features
In this chapter, the controls and connections of the LCR Meter are described, and its
basic operation is summarized in terms of the meter's specifications, features and options,
and operating modes.

Front Panel Components

The front panel and its displays, controls, and connections are shown in the following
illustration:

Fixture inputs

First, the displays, controls, and connections on the left side of the front panel are ex-
plained, and then the many buttons and keys on the right side are described.
Fixture Inputs
The input terminals labeled IL, PL, PH, and IH connect the test fixture or adapter to the
instrument, as discussed in the section in Chapter 3 on "Connecting a Component." Two
of the terminals provide a current source to the component under test, and the other two
terminals provide a high impedance connection to measure the voltage across the device.
This four-wire or "Kelvin" type of measurement setup is designed to increase accuracy by
reducing the amount of current in the voltage-sensing wires. Warning: Do not connect
any active voltage source to these terminals, especially high voltages.

Measurement Modes and the Mode Selection Keys

These keys select the measurement to make on the component under test. One of five
measurement modes may be selected: Auto, R+Q, L+Q, C+D or C+R. The selected
