In use, the pin 2 is connected to a multimeter 15, Figs. 5-8 (not shown) and the wires 5, 6 which carry crocodile clips 3, 4 at their free ends to the base and collector of a transistor whose current amplification factor is to be determined. An equation is developed giving the ...
How to Test a Camshaft Position Sensor using a Multimeter Camshaft position sensor testing is very important to check its proper functioning. These sensors can be affected by many malfunctions which can affect the sensor failure or its uneven operation. So an accurate sensor diagnosis is very impo...

Use a multimeter to measure the resistance of the two poles apart from the base electrode. Exchange the test lead and measure it again. If it is a germanium tube, the smaller resistance is used for judgment. When the smaller resistance is obtained, for a PNP transistor, the black tes...
a thousand and even until today I still train students from various big corporation. So if you’re thinking about learning how to test electronic components with a multimeter and perform electronic repair, one that you can learn from the convenience of your own home, and you’re looking to ...
The op-amp (U1) is configured as a voltage follower, with its non-inverting input (+) connected to the wiper of the potentiometer (R3). The inverting input (-) of the op-amp is connected to the emitter of the transistor (Q1) through a feedback resistor (R2). This forms a negative...
or device being tested must be turned off or batteries should be removed while in the continuity mode. Other continuity tests Test other types of switches, wires, cables and incandescent lamps (flashlight bulbs etc) to gain experience with continuity testing, which will enhance troubleshooting ...
The voltages around the oscillator stage cannot be measured with an ordinary multimeter as the leads of a millimeter will act an antenna when the circuit is operating and kill the operation of the circuit. This is certainly the case on the emitter of the second transistor, where the leads of...
2.1. Temperature Transducer Description The temperature transducer T1 was an nMOS transistor (dimensions: W = 24 µm, L = 1.5 µm) connected in diode configuration and biased with a DC constant current (IB in Figure 2). A small bias current placed the transistor in the weak inversion ...
