Due to the excessive amount of power that can be generated in
this test, only parts with an I
tested on standard curve tracer. If testing devices above 8 A, a

To measure the V
1. Set Terminal Selector to Emitter Grounded-Open Base.
2. Set Max Peak Volts to 75 V. (80 V on 370)
3. Set Mode to Norm.
4. Set Horizontal knob to 0.5 V/DIV.
5. Set Power Dissipation to 220 watts (100 watts on a 577).
6. Set Vertical knob to a sufficient setting to allow the viewing
Procedure 9: V
To measure the V
1. Set Polarity to (+).
2. Set Left-Right Terminal Jack Selector to correspond with
3. Increase Variable Collector Supply Voltage until current
Note: Model 370 current is limited to 10 A.
4. To measure V
Procedure 10: V
To measure the V
1. Set Polarity to (–).
