Kyoritsu Digital Multimeter (600V / 10A), AC/DC - 1009

Auto Range Digital Multimeter

The Kyoritsu Model 1009 is a high-performance digital multimeter engineered for precise electrical diagnostics, laboratory research, and professional troubleshooting, the instrument safely measures AC/DC voltage up to 600V and AC/DC current from micro-amps up to 10A. The device offers seamless operational flexibility by providing both auto-ranging and manual range selection, allowing technicians to lock specific measurement ranges or freeze exact readings via the Data Hold function on its high-resolution 3999-count LCD screen.

Beyond basic voltage and amperage readings, this compact 280-gram unit functions as a comprehensive diagnostic hub. It supports advanced component evaluation, including precise diode testing, capacitance measurement up to 100 microfarads, and frequency tracking for electrical signals up to 10 megahertz. For rapid circuit verification, a highly responsive continuity tester emits an audible buzzer when electrical resistance drops below 100 ohms. The system also features a specialized Relative Mode designed to evaluate minute differences between two separate, consecutive measurements.

Safety and mechanical durability are strictly prioritized in the 1009 architecture. The internal circuitry is safeguarded against overloads by a heavy-duty dual-fuse system, while the exterior is wrapped in a protective rubber holster to shield the delicate internal electronics against mechanical shock and drops in harsh industrial environments. Fully compliant with IEC 61010-1 CAT III 300V global safety standards, the meter maximizes operational efficiency with an automatic power-off function that shuts down the device after 30 minutes of inactivity to preserve its internal battery lifecycle.

Key Features & Benefits:

• Voltage Measurement: Safely reads up to 600V AC/DC with a highly reliable baseline accuracy of ±0.6% rdg on DC circuits.

• Broad Current Coverage: Accurately measures from sensitive micro-amps up to 10A in both AC and DC, bridging the gap between low-voltage electronics and high-power industrial circuits.

• High-Resolution Display: Features a crystal-clear 3999-count LCD screen that provides immediate, easily readable numerical outputs.

• Versatile Range Selector: Offers operators the choice between auto-ranging for rapid diagnostics and manual range controls for highly specific testing.

• Range Hold Function: Allows the technician to lock the current measuring range manually to prevent the device from auto-shifting during fluctuating loads.

• Diode & Capacitance Testing: Accurately evaluates diode forward-voltage drops and tests electrical capacitors up to 100 microfarads.

• Frequency & Relative Mode: Tracks electrical signal frequencies up to 10 megahertz and utilizes a Relative Mode to evaluate the exact numerical differences between two separate measurements.

• Audible Continuity Tester: Integrates a built-in buzzer that sounds instantly when circuit resistance falls below 100 ohms, confirming uninterrupted electrical paths.

• Data Hold Function: Freezes the current displayed reading on the screen with a single press for safer data recording post-measurement.

• Auto Power Off: Intelligently shuts down the instrument after 30 minutes of unused idle time to conserve the dual R6 batteries.

• Mechanical & Electrical Protection: Features a protective rubber outer holster to absorb physical shocks, alongside a robust dual-fuse system that safeguards internal electronics from unexpected current spikes.

• Safety Certification: Fully tested and compliant to meet rigorous IEC 61010-1 CAT III 300V international safety standards.
