About This Product
Students set independent base and collector bias and read all four meters together to work out gain without breaking the circuit. Switching between NPN and PNP circuits shows the differences in polarity between the two bipolar transistor types.
Frequently Asked Questions
Why does the Digital Transistor Characteristics Apparatus use digital meters?
Its four integrated digital meters remove parallax error and let all readings be taken together without switching leads.
