Meter for Automotive Maintenance & Digital Multimeter Functions

Sanwa DCM400AD: The Ultimate Digital Clamp Meter for Automotive Maintenance

The Sanwa DCM400AD is a versatile and robust digital clamp meter combined with multimeter functions, specifically engineered for the demands of automotive diagnostics and maintenance.

Precision and Versatility for Automotive Professionals

Designed to meet the IEC measurement category CAT.III 300V, the DCM400AD is an essential tool for any mechanic or automotive technician. It provides accurate measurements for both AC and DC currents up to 400A and can handle AC/DC voltages up to 600V. This wide range makes it perfect for diagnosing everything from starting and charging systems to complex electronic circuits within a vehicle. Additionally, it measures resistance up to 400Ω and includes a continuity test with an audible buzzer, making it easy to identify shorts and open circuits.

User-Friendly Design with Advanced Features

The device features a clear 4000-count display complemented by a 42-segment analog bar graph, which provides a quick visual representation of changing readings, similar to an analog meter. Key functions enhance usability:

• Data Hold: Freezes the current reading on the screen, allowing you to record it after disconnecting from the circuit.
• Range Hold: Enables manual selection of the measurement range for specialized testing.
• Relative Value (Zero Function): Allows you to zero out the meter for offset removal or to measure deviations from a reference value.

The DCM400AD is built for convenience with features like auto power-off to conserve battery life and a low battery indicator to ensure you're never caught without power.

What's in the Box? Each package includes the DCM400AD meter, one set of high-quality test leads, a durable carrying case for protection, and a comprehensive instruction manual.
