Product OverviewThe Hioki DT4256 is a versatile, high-performance digital multimeter designed for professional service and maintenance applications. As a key model in the Hioki DT4200 series, it is engineered for field technicians who need a robust, all-around diagnostic tool. It excels in diverse environments, from industrial electrical panels to complex electronic circuits, offering a balance of high-speed response, rugged build quality, and safety features that meet the demanding requirements of modern electrical work. Key FeaturesVersatile Measurement Suite: Offers a complete range of diagnostic functions, including True RMS AC/DC voltage and current, resistance, capacitance, frequency, and continuity/diode testing. Specialized Industrial Capabilities:Low-Pass Filter: Effectively blocks high-frequency harmonic noise, allowing for stable voltage and current measurements on the secondary side of inverters or variable frequency drives (VFDs). Direct Current Handling: Features high-range DC/AC current measurement (up to 10 A) and supports optional external clamp-on probes for high-current applications (up to 1000 A). Smart Safety & Convenience:Voltage Detection: Includes a built-in non-contact voltage (NCV) detection function for quick, safe pre-checks. Auto-Hold & Data Management: Features an "Auto-Hold" function that freezes readings when stable, and optional USB connectivity for real-time data logging and PC-based analysis. Rugged Field Design: Engineered with a dust-proof enclosure and drop-proof housing (tested for 1 m falls onto concrete). It also features a wide operating temperature range (-25°C to 65°C), ensuring reliability in harsh conditions. 4-20mA Process Control: Capable of measuring 4-20 mA instrumentation signals and displaying the value as a percentage (0–100%), which is vital for industrial process control loops.
