Multifunctional Leakage Clamp Meter

Sanwa DLC470: The Multifunctional Leakage Clamp Meter for Professionals

The Sanwa DLC470 is a robust, true RMS digital leakage clamp meter specifically engineered for accurate diagnostics and safety in CAT. III environments. This versatile tool is essential for electricians, maintenance engineers, and technicians who need to detect and measure current leakages in power lines with precision.

Core Functionality and Precision Measurement

The primary function of the DLC470 is to measure AC current leakages with a high resolution of 0.01mA, enabling the detection of even minor faults that other meters might miss. Its capabilities extend beyond leakage detection, making it a comprehensive multimeter for everyday tasks.

• Current Measurement: Measures AC current up to 400 Amperes with a high accuracy of ±(1.2%+5).
• Voltage Measurement: Reliably measures both AC and DC voltages up to 600 Volts.
• Resistance & Continuity: Measures resistance up to 999.9Ω and includes a continuity test with an audible buzzer that sounds at 30Ω or less.

Advanced Features for Accurate Diagnostics

The DLC470 is equipped with features designed to simplify the diagnostic process and ensure the most accurate readings possible, even in noisy electrical environments.

• Low Pass Filter (LPF): The ACA LPF function filters out high-frequency noise, which is common with inverters and variable frequency drives. This ensures stable and precise current readings.
• Band-Pass Filter (BPF): This function isolates the fundamental 50Hz/60Hz frequency range for ACmA and ACA measurements, eliminating harmonics for a truer reading of leakage current.
• Data Hold & MAX/MIN Hold: The standard hold function freezes the current reading on the screen for easy recording. The MAX/MIN function captures and displays the highest and lowest values measured over time, which is invaluable for identifying intermittent faults or power fluctuations.
• Backlit Display: The large, backlit LCD screen provides clear visibility in poorly lit conditions, ensuring readings can be taken accurately and safely in any environment.

Designed for Field Use

Built with the field professional in mind, the DLC470 is both durable and user-friendly. It complies with the rigorous IEC61010-1 CAT.III 600V safety standard, making it safe for use on three-phase distribution circuits.

• Power Management: The device features an auto-power-off function that activates after 30 minutes of inactivity to conserve battery life, which can be disabled if continuous monitoring is required. It operates on two standard LR03 (AAA) batteries.
• Ergonomics: The clamp has a generous 35mm diameter, accommodating a wide range of conductor sizes.
• Complete Kit: The meter comes ready to use out of the box with a set of test leads, a durable carrying case for protection, and a detailed instruction manual.
