How to Use the UJT Characteristics Apparatus

1. Confirm the UJT type, voltage range, current range, polarity, and circuit configuration before use.
2. Place the apparatus on a dry, stable electronics-lab bench.
3. Connect the circuit according to the approved UJT experiment diagram.
4. Set the emitter and base supply controls to their lowest safe starting values.
5. Increase the emitter voltage gradually and record emitter voltage and emitter current readings.
6. Plot the readings to identify peak point, valley point, and negative resistance behaviour.
7. Switch off the supply before changing connections or replacing semiconductor components.

Safety note: Use the apparatus only within confirmed low-voltage and low-current ratings. Incorrect polarity, excessive current, or wrong biasing can damage the UJT and connected meters.

Care & Maintenance
