Informatie

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).
