True RMS Clamp Meter for Electrical and HVAC Work / DMM

Sanwa DCM660R True RMS Clamp Meter: Your Essential Tool for Electrical and HVAC Diagnostics

The Sanwa DCM660R is more than just a clamp meter; it's a versatile digital multimeter (DMM) engineered for professionals in electrical and HVAC fields. Designed for reliability and precision, this instrument combines robust measurement capabilities with advanced features, making it indispensable for a wide range of applications.

Unmatched Performance and Safety:

• High Current Measurement: Effortlessly measure AC currents up to an impressive 660 Amperes, perfect for diagnosing high-power systems.
• True RMS Accuracy: Unlike traditional meters, the DCM660R utilizes True RMS technology, providing accurate readings on non-sinusoidal waveforms—a common occurrence in modern electrical systems. This ensures you get precise measurements every time, reducing diagnostic errors.
• Comprehensive DMM Functions: Beyond current, this device handles all your essential multimeter needs. Measure AC+DC voltage, resistance, and frequency, and conduct quick continuity tests to identify open or closed circuits. This eliminates the need for multiple tools, streamlining your workflow.
• CAT III Safety Rating: Built to stringent safety standards (IEC61010-1), the DCM660R is rated for CAT III 600V environments, offering enhanced protection for users working on distribution-level electrical installations.
• Inrush Current Measurement: Capture critical startup current surges with the dedicated inrush function, vital for troubleshooting motors and other inductive loads.
• Max/Min Value Hold & Data Hold: Easily track fluctuations or freeze measurements on the large display for convenient recording and analysis.

User-Friendly Design:

• Large, Backlit LCD Display: The 6600-count LCD with backlight ensures clear visibility of readings, even in dimly lit conditions, improving efficiency and reducing eye strain.
• Relative Value Measurement: Simplify differential measurements, making it easier to compare readings against a reference point.
• Auto Power Save: Conserve battery life with an automatic power-off feature (15 minutes after last operation), ensuring your meter is ready when you are.
• Ergonomic and Durable: With a comfortable grip and robust construction, the DCM660R is built to withstand the rigors of daily field use. Its compact size (H208×W69×D38mm) and light mass (approx. 265g) make it highly portable.
• Generous Clamp Diameter: A Φ30mm clamp diameter accommodates a wide range of conductors, including bus bars up to 10x50mm.
