Manufacturer's Data: 

The SR720 LCR Meter measures passive components with as little as 0.05 % error. This easy-to-use instrument is quick to setup, adjust and calibrate. The SR720 is ideal for applications such as incoming inspection, quality control, automated test, and general bench top use.

Front-Panel Display

A 5-digit LED display shows measured values, entered parameters, instrument status, and user messages. When making measurements, the major parameter (L, C or R) is shown on the left display and the appropriate minor parameter (Q, D or R) is shown on the right display.

Making Measurements

Measurements can be performed at test frequencies of 100 Hz, 120 Hz, 1 kHz, 10 kHz and 100 kHz. A built-in drive voltage can be set to preset values (0.1, 0.25 and 1.0 V) or adjusted from 0.1 to 1.0 V in 50 mV increments. Measurements are taken at rates of 2, 10 or 20 samples per second. Consecutive readings can be averaged between two and ten times for increased accuracy. Both series or parallel equivalent circuit models of a component are supported. Capacitor measurements use either the internal 2.0 VDC bias or an external source of up to 40 VDC.
