The current limiting resistor R should be large enough to prevent excessive current from flowing through the transistor and the ammeter. Under the condition of emitter-base open circuit, increase the voltage until the specified test current is reached. If the applied voltage is greater than the maximum value of (BR)CED at the specified test current, the transistor is qualified. Additional Notes:
