Understanding Hall Effect Sensors
Understanding Hall Effect Sensors

... There are several ways to troubleshoot Hall Effect Sensors. One is to use a self-powered “indicator light” type of Hall Effect Tester that flashes when the sensor’s output signal changes. If the sensor is being tested on the vehicle, simply plug the tester into the sensor, then crank the engine and ...

... Note: it is possible to establish a PC to PLC connection using RS232 even when the PLC is set to RS485 (this will eliminate the need to open the controller for jumper setting). To do so, removes the RS485 connector (pins 1 & 6) from the PLC and connect a standard RS232 programming cable instead. Not ...

... The amplifier takes a small input signal from a source such as an ipod or mp3 player and reproduces the signal at its output. The signal at the output is much larger than the input (thats what amplify means) which allows it to drive a loudspeaker. The fuse tester can also be used to test the continu ...

Ground loop (electricity)

In an electrical system, a ground loop is an equipment and wiring configuration which results in excessive unwanted current in a conductor connecting two points that are supposed to be at the same electric potential, often ground, but are actually at different potentials.Ground loops are a major cause of noise, hum, and interference in audio, video, and computer systems. They do not in themselves create an electric shock hazard, the inappropriate connections merely create a not necessarily very good instance of Electrical_bonding, which is explicitly required by safety regulations in certain circumstances. In any case the voltage difference between the ground terminals of each item of equipment is small. A severe risk of electric shock occurs when equipment grounds are improperly removed in an attempt to cure the problems thought to be caused by ground loops.
