Adjustable decade resistance box (variable resistor tester) designed for precise low‑ohm work and portable field use. Key benefits Precise, repeatable adjustments: 0 to 9 ohms total range with fine 0.1 ohm stepping lets you dial in exact resistance values for testing, calibration, and troubleshooting. Reliable results: Built to deliver consistent measurements with a tolerance level of 1, so readings are dependable across different tasks. Durable, practical construction: ABS housing provides impact resistance and long service life in bench or field environments. Ready for mobile work: Supplied test leads with clips make on‑site connections fast and convenient, reducing setup time and keeping hands . What this product solves Eliminates guesswork when you need small, accurate resistance values for circuit verification or sensor calibration. Speeds up fault isolation and component checks by allowing you to swap precise resistance values quickly without soldering or assembling discrete parts. Provides a compact, rugged alternative to bulky instruments when you need a simple, reliable variable resistance on the go. Standout features Fine resolution: 0.1 ohm step size for tight control over low resistance values. Wide usable range: 0–9 ohms covers many common low‑ohm testing scenarios. Robust material: ABS construction balances weight and durability for repeated use. Portable connections: Included test leads with clips simplify temporary and field hookups. Specifications Resistance range: 0 to 9 ohms Step size: 0.1 ohm Tolerance: level of 1 Body material: ABS Accessories: test leads with clips included Typical applications Electronics bench testing and component verification: set exact resistance values to test amplifiers, filters, or current sensing elements. Field service and maintenance: quickly substitute known resistances for troubleshooting wiring, connectors, or low‑ohm circuits during on‑site repairs. Educational labs and prototyping: demonstrate the effect of small resistance changes and provide predictable loads for experiments. Usage notes Use the included clips for secure, temporary connections; ensure contacts are clean for results. Adjust in 0.1 ohm increments to target precise resistance settings; verify with your meter as needed. A compact, accurate, and durable decade resistance box that simplifies low‑ohm testing and on‑site measurements while providing reliable performance.
