SR715 and SR720 LCR Meters

  • Manufactured by: SRS Stanford Research Systems

Quick Overview

The SR715 LCR Meter and SR720 LCR Meter 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.

Description

The SR715 LCR Meter and SR720 LCR Meter 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.

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 (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.

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.

Simple to Operate

The power and flexibility of the SR715 LCR meter and SR720 LCR meter 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.
