- Multiple Models Available: Choose from 1M, 10M, 100M, or 1000M configurations to match your specific circuit requirements.
- Precision Accuracy: ±2% resistance accuracy at 23°C ±5°C ensures dependable calibration and circuit verification results.
- Compact & Sealed Design: Small sealed enclosure (64 × 58 × 35.5 mm, excluding binding posts) protects internal resistor elements and simplifies bench integration.
- Wide Operating Range: Functions reliably from -40°C to 60°C at up to 80% RH — ideal for field or lab conditions.
- Standard Binding Posts: Ø13mm × 24mm posts with 40mm spacing and Ø4mm socket / M6 stud connections for easy integration with standard test leads.
Key Applications
- Circuit Testing & Debugging: Simulate known resistance loads to verify DC power supply performance, drive circuits, and protection circuits. Adjust resistance to change load current (I = U/R) and confirm output voltage stability under rated load.
- Load Simulation: Substitute for actual loads — motors, sensors, or other devices — during pre-installation testing of control and drive circuits.
- Fault Diagnosis: Compare theoretical vs. measured values using a known resistance to pinpoint abnormal load conditions such as short circuits, open circuits, or resistance drift.
- Instrument Calibration: Serve as a traceable standard resistance source for calibrating multimeters, ohmmeters, DC power supplies, and resistance testers.
- Educational Experiments: Ideal for university labs and electronics teaching environments requiring accurate, adjustable resistance references.
