Category: Measurement instruments
Group: LCR Meter
Description: LCR Bridge
Information:
                                    The Leader LCR-740 is designed for measurement of
resistance, capacitance and inductance over a wide range.
The instrument is completely self-contained, including
a battery for measurements of R (DC); as well as, C and L
with a 1kHz oscillator and null detecting amplifier system.
A 3-digit readout is used for measured values. Input
connections are provided for use of external DC or AC
(50Hz-40kHz) sources, and for an AC Adapter (LPS-169). 

These manuals are available for the above equipment:
