Stanford Research SR720 LCR Meter, 100 kHz, with RS-232, GPIB, Handler InterfaceRefurbished
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 benchtop use.
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.
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 2 and 10 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 DC source of up to 40 volts.
