Digital Multimeter with True RMS / High Input Impedance

Sanwa RD701: Precision Digital Multimeter with True RMS & High Input Impedance

Elevate your diagnostic capabilities with the Sanwa RD701, a highly accurate and versatile 4000-count True RMS digital multimeter, boasting a 0.3% basic DCV accuracy. Engineered for reliability, the RD701 is an indispensable tool for professionals working with low-voltage circuits, home appliances, and various small communications equipment.

Key Differentiators & Advanced Functionality: While its counterpart, the RD700, offers core measurement, the RD701 stands out with its True RMS (Root Mean Square) capability. This crucial feature allows for precise measurement of impure AC sine waves, providing accurate readings even in environments with distorted waveforms—a common occurrence in modern electrical systems.

Comprehensive Measurement Range: The RD701 delivers exceptional performance across a broad spectrum of electrical parameters:

• Voltage: Measures DCV up to 1000V and ACV up to 1000V.
• Current: Handles DCA and ACA from microamps (400µA) up to 10A.
• Resistance: Covers a wide range from 400Ω to 40MΩ.
• Capacitance: Accurately measures from 500nF up to 3000µF.
• Frequency: Measures frequencies from 50Hz to an impressive 1MHz.
• Temperature: Equipped for temperature measurements from -20°C to 300°C using an optional K-type thermocouple sensor (K-250PC).
• Diode and Continuity Tests: Essential for circuit diagnostics, featuring an audible buzzer for continuity and a clear diode test function.

User-Centric Design & Safety Features: Designed with the user in mind, the RD701 integrates several thoughtful features:

• Large Format Display: A clear 4000-count display ensures easy readability of measurements (9999 for frequency, 5000 for capacitance).
• Automatic & Manual Ranging: Offers flexibility and convenience for different measurement scenarios.
• Max Recording Measurement: Capture peak values for transient signals.
• Range Hold, Data Hold, and Relative Function: Tools to simplify data capture and analysis.
• Safety Alarm: An audible alert prevents improper test lead insertion into current terminals, protecting both the device and the user.
• Auto Power-Off: Conserves battery life by automatically shutting down after 30 minutes of inactivity (cancellable).
• Robust Protection: Features a high-capacity fuse (12.5A/500V IR20kA and 0.63A/500V IR50kA) for enhanced safety.
• Durable Build: Comes with a protective rubber holster, integrated wall hanger, and a convenient tilt stand, providing both impact resistance and ergonomic utility.

Included Accessories: Each Sanwa RD701 package includes the meter, a durable rubber holster, a comprehensive instruction manual, and one set of high-quality test leads, ensuring you're ready to get to work right out of the box.

Optional Enhancements: For extended current measurement capabilities, consider the ACS101 Clamp Current Sensor (sold separately).
