Adjustable Decade Resistor Box (Variable Resistor) What it does and why it matters Provides precise, repeatable resistance values for calibration, circuit testing, and training. The fine resolution and reliable accuracy let you simulate loads, verify instrument responses, and teach measurement techniques without guesswork. Key features and benefits Wide, finely adjustable range: 0 to 9999.9 ohms in 0.1 ohm increments for exact setting and smooth tuning of circuit behavior. Reliable measurement performance: level1 measurement accuracy and a low withstand value under 0.035 ohms deliver consistent, trustworthy readings across test setups. Durable ABS construction: tough black ABS housing resists wear and provides stable performance during repeated use in labs, workshops, or field work. Readytouse portability: compact 165 x 125 x 60 mm form factor and included 90 cm test lead set with clips for fast connections and easy transport between job sites, classrooms, and bench stations. How it solves problems Eliminates uncertainty when calibrating equipment or validating circuit responses by providing precise, selectable resistance values. Reduces setup time with included long leads and clip connectors for quick, secure hookups. Withstands routine handling and movement thanks to a rugged case that preserves accuracy and component alignment. Practical applications Educational labs: Demonstrate resistor networks, teach measurement techniques, and run handson experiments with repeatable, stepwise resistance settings. Circuit testing and development: Simulate sensors or loads during debugging, tune circuits, and verify behavior across a wide resistance range. Industrial calibration and maintenance: Use as a stable reference for instrument calibration, field verification, and troubleshooting tasks.
