• Notes

• This instrument has been designed to facilitate the work of engineers and technicians in selecting the correct transistor for their assemblies.
  Fixing the polarization and emitter-collector voltage, we can determinate  gain β and input resistance R_i. 
  Direct and reverse current of the diodes is read directly from the dial of a microammeter.
  
  The measurement ranges are: β 0 to 500; R_i 0 to 10 kΩ and I_c 0 to 1A.

  The instrument comprises: Two supplies stabilized at 1 per cent in relation to the mains, one for the collector that gives 1 A at 30 V, the other to supply the base that gives 0.1 A at 30 V.
  Three meters that permits direct readings of voltage V_c - current  I_c and polarization current I_b.
