Bench-Type LCR Meter (DM-9972SD) Digital Multimeter

Lutron Bench-Type LCR Meter & Digital Multimeter with SD Card Data Logging (DM-9972SD)

The Lutron DM-9972SD is a high-performance bench-type instrument that combines a full-function digital multimeter with a precision LCR analyzer. Designed for laboratory, production, engineering, and advanced service applications, it measures voltage, current, resistance, capacitance, inductance, impedance, dissipation factor (D), quality factor (Q), phase angle (θ), and DCR with selectable test frequencies. The built-in real-time SD card data logger allows long-term recording without software installation, generating files directly readable on any computer.

• Dual instrument design: Full-function digital multimeter plus precision LCR analyzer.
• Real-time SD logging: Records measurements in spreadsheet-ready format (1–16 GB cards supported).
• Selectable LCR test frequencies: 100 Hz, 120 Hz, 1 kHz, and 10 kHz for optimal component characterization.
• Multiple measurement modes: Series (SER) and Parallel (PAL) equivalents.
• Simultaneous parameter display: LCD shows primary and secondary measurements at the same time.
• High accuracy and stability: Designed for bench or production testing.
• Large easy-to-read display: 52 mm × 38 mm backlit LCD for laboratory viewing.
• Auto and manual range selection: Ideal for component evaluation and troubleshooting.
• Advanced DMM functions: Voltage, current, ohms, diode check, continuity, and frequency.
