It uses internally preset resistor units — including metal film and wirewound resistors — switched via a mechanical or electronic mechanism. This provides a traceable, stable, and flexibly adjustable standard resistance load or calibration reference for DC circuits.\u003c\/p\u003e\n\n\u003ch3\u003eKey Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCircuit Testing \u0026amp; Debugging:\u003c\/strong\u003e Connect a known resistance load to verify DC power supply performance, simulate actual loads (e.g., motor or sensor equivalents), and confirm that control circuits respond correctly — all before final installation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad Simulation:\u003c\/strong\u003e Adjust resistance values to change load current (per Ohm's Law: I = U\/R) and observe output voltage stability under rated load conditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFault Diagnosis:\u003c\/strong\u003e Compare theoretically calculated values with actual measurements to isolate faults caused by abnormal load resistance — short circuits, open circuits, or resistance drift.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstrument Calibration:\u003c\/strong\u003e Use as a precision resistance standard source to calibrate multimeters, ohmmeters, DC power supplies, and resistance testers, ensuring accurate measurement results across your instruments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeaching \u0026amp; Lab Experiments:\u003c\/strong\u003e Ideal for educational settings where students need a safe, repeatable reference resistance for hands-on experiments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFull Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModels Available\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1M, 10M, 100M, 1000M\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eABS\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eColor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Resistance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e100 MΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eResistance Accuracy\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e±2% (at 23°C ± 5°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eResistance Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2000 VDC (between two binding posts)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eResistance Power\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.25 W\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-40°C to 60°C, ≤80% RH\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions (L × W × H)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e64 mm × 58 mm × 35.5 mm (excluding binding posts)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBinding Post Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eØ13 mm × 24 mm, 40 mm spacing\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eElectrical Connection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSocket: Ø4 mm × 17 mm; Stud: M6\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBattery Required\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOrigin\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMade in Mainland China\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × 2000VDC Industrial-Grade DC Resistance Box\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eRelated Products You May Find Useful\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/air-compressor-pressure-gauge-0-10-0-12-0-25-bar-hydraulic-diy\"\u003eAir Compressor Pressure Gauge 0-10\/0-12\/0-25 Bar | DIY Tool\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/electromagnetic-induction-tester-coil-motherboard-fault-detector\"\u003eElectromagnetic Induction Tester – Coil \u0026amp; Circuit Fault Detector\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eNote: Actual color may vary slightly from images due to monitor brightness and lighting conditions.
