Reverse these leads to read the meter in an opposite direction after checking it. While touching a lead towards the base while the other connects to an emitter, you must check the reading of the emitter on its base in the two directions. The transistor would display a reading for one direction as well as infinity for the other if it is functioning properly. Review the reading then share your advice. Touch a lead from of the meter into a base lead whilst you place its other on your collector lead to check the reading of the collector in both base-collector directions. If the transistor is operating in the analog environment, set it using a low ohm scale. If your digital multimeter has the diode setting, use it in this step if not, use ohms setting. You should have confidence because the placements of the points vary depending on the transistor. By being certain of the orientation of leads, you should request a catalog from your electronics supplier. These leads on some transistors are labeled for simple identification. Watch out for the transistor that you will be testing for its collector, base, as well as emitter leads. To prevent turning off stored power, use the screwdriver with insulation at the handle end. Make sure that there’s no power present on the circuit board before simultaneously touching a capacitor’s two terminals with any metal. The battery should then be removed after unplugging its AVC power connection. Step 1īefore testing your transistor, make sure that there’s no electricity flowing through the circuit by ensuring it is switched off. A step-by-step tutorial for testing a PCB transistor is provided here. Be sure you understand what is expected of you before you start the procedure. Because of this, it is crucial that you test them in order to make sure they are operating as intended. When they are flawed, the circuit fails as a result. In circuits, transistors play a crucial role, thus it’s crucial to make sure they’re functional.
