LCR Meters SR715 and SR720 — LCR meters with test frequencies to 100 kHz SR715 & SR720 LCR Meters · 0.05 % basic accuracy (SR720), 0.2 % (SR715) · 5-digit display of L, C, R and Q or D · Test frequencies to 100 kHz (SR720) · Up to 20 measurements per second The SR715 and SR720 LCR Meters measure passive components with as little as 0.05 % error. These easy-touse 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. Front-Panel Display · External capacitor bias up to 40 V 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 · GPIB & Parts Handler interfaces (SR720) Measurements can be performed at test frequencies of 100 Hz, 120 Hz, 1 kHz, 10 kHz and 100 kHz (SR720 only). 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. · Binning and limits for parts sorting Stanford Research Systems 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.

Simple to Operate The power and flexibility of the SR715/720 does not come at the expense of ease-of-use. A convenient AUTO measurement mode automates the selection of setup parameters and quickly determines the appropriate device model for whatever component is being measured. Up to nine instrument setups can be stored in non-volatile memory for quick recall at a later time. progressively larger bins (e.g., ±1 %, ±2 %, ±3 %). Sequential bins can have different nominal values, each separated by a percentage or a nominal value and asymmetrical limits. Binning parameters are also easily stored...
