Sanwa LCR701 Handheld Digital LCR Meter

Description

The Sanwa LCR701 is a high-performance handheld digital LCR meter used for accurate measurement of inductance (L), capacitance (C), and resistance (R). It is a versatile and portable device with advanced features that rival many benchtop LCR meters.

Key Features

• Automatic L/C/R selection: The meter can automatically identify and select the correct measurement function for a component, making it easy to use.
• Multiple test frequencies: It can perform measurements at five different frequencies: 100 Hz, 120 Hz, 1 kHz, 10 kHz, and 100 kHz.
• Series/Parallel measurement mode: The LCR701 offers both selectable series and parallel measurement modes to accurately characterize components.
• Device sorting mode: This feature allows users to quickly sort passive components for incoming inspections or quality control by setting PASS/FAIL thresholds.
• DC resistance (DCR) function: The meter can measure DC resistance across seven different ranges, from 200.00 Ω up to 200.0 MΩ.
• Open/Short calibration: A calibration function helps to minimize measurement errors caused by test leads and fixtures.
• Five-terminal measurement: The unit supports five-terminal measurement (four terminals plus guard shielding), which helps increase accuracy.
• PC connectivity (optional): With an optional optical link USB communication unit (LCR-USB) and free software, measurement data can be transferred to a PC.
• Additional functions: Includes a data hold function, backlight for low-light conditions, auto power-off, and relative value measurement.
• Sub-parameter measurements: In addition to L, C, and R, the meter can measure secondary parameters such as:

                  1. Dissipation Factor (D): The measure of the loss in a component.

                  2. Quality Factor (Q): The ratio of a component's reactance to its resistance.

                  3. Phase Angle (θ): The phase difference between voltage and current.

                  4. Equivalent Series Resistance (ESR): The total internal resistance of a component.
