KYORITSU 1009 Digital Multimeter
The KYORITSU 1009 Digital Multimeter embodies a marriage of robust safety engineering and intuitive operation within a compact form. Housed in a reinforced casing with dual insulation, it presents a reassuring solidity in the hand while protecting users from accidental contact with live circuits . The clear, auto-ranging LCD display adapts seamlessly to measured values, minimizing manual adjustments and keeping the interface uncluttered. Beneath this simplicity lie thoughtfully arranged controls: a tactile function switch that clicks sharply into place, and dedicated keys for zeroing, range override, and data hold, each positioned for ergonomic thumb access.
Internally, the meter employs advanced signal-processing circuitry that filters out electrical noise, ensuring that readings remain stable even in electrically “dirty” environments. A built-in relative mode lets operators compare live measurements against a stored baseline without navigating menus, and a backlit display automatically illuminates low-light conditions, preserving visibility without added bulk . Despite its sophisticated electronics, the instrument maintains a slender profile, slipping easily into a tool pouch or pocket. Overall, the 1009 model strikes a balance between rugged reliability and user-centric design, offering swift adaptability across a variety of measurement scenarios without overwhelming the user with complexity.
Features:
- Designed to international safety standards (IEC 61010-1, IEC 61010-2-033 CAT III 300 V, Pollution Degree 2; IEC 61010-031).
- REL (relative) function to display the difference between live readings and a stored baseline.
- Auto power-off to conserve battery when idle.
- Data hold function to freeze the displayed measurement.
- Diode and continuity check modes with audible buzzer.
- Auto-ranging across voltage, current, resistance, capacitance, and frequency ranges.
- Frequency measurement capability (1 Hz–10 MHz).
- DUTY-cycle measurement (pulse-width/pulse-period as a percentage).
- Fuse-protected current inputs for enhanced safety.
- Holster protection against mechanical shock during field use.
