Multimeter (DM-9680) with Test Leads & RS-232 Interface

Lutron Digital Multimeter with RS-232 Interface (DM-9680)

The Lutron DM-9680 is a versatile, high-accuracy digital multimeter designed for electrical, industrial, and service applications. It provides comprehensive measurement functions including voltage, current, resistance, continuity, diode test, and transistor hFE. The built-in isolated RS-232 interface allows data transfer to a PC for logging and analysis when used with optional software. Its large backlit LCD, rotary selector, and overload protection make it reliable for both field and bench use.

• Multi-function measurement: ACV, DCV, ACA, DCA, resistance, continuity, diode test, and transistor hFE.
• Meets IEC safety standards: Conforms to IEC 1010 requirements.
• High internal impedance: Minimizes measurement loading errors.
• Large backlit display: 18 mm (0.7") 3½-digit LCD for easy visibility.
• Isolated RS-232 output: Photo-coupled interface for safe PC connectivity.
• Overload protection: Protection on all ranges including fuses for current inputs.
• Drop-resistant housing: Durable design for field reliability.
• Optional PC software: Enables data logging, charting, and recording applications.
