Procedure 3: (-) V
To measure the (-)V
1. Set Polarity to (–).
2. Repeat Procedures 1 and 2. (Read measurements from
Procedure 4: V
To measure the V
1. Set Variable Collector Supply Voltage Range to 1500 Max
2. Set Horizontal knob to a sufficient scale to allow viewing of
3. Set Vertical knob to 50 µA/DIV.
4. Set Polarity to AC.
5. Set Mode to Norm.
6. Set Power Dissipation to 10 W.
7. Set Terminal Selector to Emitter Grounded-Open Base.
8. Set Left-Right Terminal Jack Selector to correspond with
Procedure 5: V
To measure the V
Supply Voltage until breakover occurs. (Figure AN1006.23) The
voltage at which current begins to flow and voltage on CRT does
not increase is the V
Procedure 6: I
To measure the I
amount of device current just before the device reaches the
breakover mode. The measured current at this point is the I
value.
