LCR meters are typically used
component testing. This one does not have connectors for
port but rather a built-in fixture to test leaded components.
The SR715 is the low end LCR meter in the Stanford
line and the SR720 is the high end unit that
100 kHz test frequency, GP-IB, RS-232 and Handler
SR715 has just the RS-232 interface and only goes to 10 kHz..
May be the basis of the HP 4263A LCR meter.
frequencies: 10 kHz, 1 kHz, 120 Hz or 100 Hz.
The upper two
frequencies are typically used to test audio components and
two for testing power supplies that work from 60 or 50 Hz
Equivalent Circuits: R + Q, L + Q, C + D, C + R
The last circuit (C+R) may be good for estimating the ESR of
Drive Voltage: 1.0, 0.25, 0.10
The lower drive voltages are handy when testing things like
capactance, i.e. to keep from turning on the diode.
is missing the schematic diagram. For that
need to purchase a manual from SR.
