📊 Technical Specifications

🚀 Applications

• Circuit Testing & Calibration – Set precise resistances for measurements

• Education & Labs – Teach Ohm’s Law, voltage dividers, etc.

• Prototyping – Simulate sensors, load testing, signal conditioning

• Repair & Troubleshooting – Replace unknown resistors in circuits

• DIY Electronics – Adjustable loads for power supplies, amplifiers

🔌 How It Works

• 8 Rotary Switches = 8 Decades of resistance:

  • 1Ω, 10Ω, 100Ω, 1kΩ, 10kΩ, 100kΩ, 1MΩ, 10MΩ

• Each switch (0-9) adds resistance in its decade.

• Example:

  • 1Ω (switch 1) + 20Ω (switch 2) + 300Ω (switch 3) = 321Ω total

⚠ Safety Notes

• Do not exceed 1/2W per resistor! (For high currents, parallel resistors.)

• Max 50V DC – Avoid high-voltage applications.

• Heat dissipation – Ensure proper ventilation at high resistances.
