Stanford LCR Meter

The SR715 and SR720 LCR Meters measure passive components with as little as 0.05 % error. These easy-to-use instruments are quick to setup, adjust and calibrate. The SR715 and SR720 are ideal for applications such as incoming inspection, quality control, automated test and general benchtop use.

Features:

• 0.05 % basic accuracy (SR720), 0.2 % (SR715)
• 5-digit display or L, C, R and Q or D
• Test frequencies to 100 kHz (SR720)
• Up to 20 measurements per second
• Binning and limits for parts sorting
• External capacitor bias up to 40 V
• RS232, GPIB and Parts handler interfaces

Measurements can be performed at test frequencies of 100 Hz, 120 Hz, 1 kHz, 10 kHz and 100 kHz (SR720). A built-in drive voltage can be set to preset valuves (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 2.0VDC bias or an external source of up to 40 volts.
