Elenco Transistor-Diode Tester Model DT-100

circuit testing. It identifies NPN and PNP transistors, checks various types of diodes, and measures the relative beta of transistors.

Applications:

• Diode Testing: Suitable for germanium, silicon, power, LEDs, and zener diodes.

• Transistor Testing: Applicable to germanium, silicon, power, RF, audio, switching transistors, and FETs.

• In-Circuit Testing: Capable of testing components without removal from circuits with certain resistance thresholds.

Specifications:

• Diode Mode:

  • Identifies cathode or anode leads.

  • Operates in circuits with resistors as low as 5kΩ.

• Transistor Mode:

  • Identifies NPN and PNP types.

  • Tests transistors in circuits with base or collector resistors as low as 100Ω.

  • Measures relative beta of two transistors.

• Power Supply: Requires a standard 9V battery (not included).

Product Description: The DT-100 features polarity indicators for both transistors and diodes, facilitating easy identification of component leads. Its high-gain circuit design allows for effective testing even in circuits with low resistance values. The tester is compact and user-friendly, making it suitable for hobbyists, technicians, and professionals in the electronics field.
