All countries have their own electrical safety standards that must be complied with. To meet to these standards, electrical products and installations must pass electrical safety tests. Some types of electrical safety tests include: dielectric withstand test (also called a hipot test) insulation resistance test (IR test) earth continuity test ...
On-board diagnostics (OBD) is a term referring to a vehicle's self-diagnostic and reporting capability. In the United States, this capability is a requirement to comply with federal emissions standards to detect failures that may increase the vehicle tailpipe emissions to more than 150% of the standard to which it was originally certified.
For example, if a fault is detected in hydraulic system 1, then the truth table sends an event to the state chart that the left inner actuator should be turned off. One of the benefits of this model-based FDI technique is that this reactive controller can also be connected to a continuous-time model of the actuator hydraulics, allowing the ...
A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.
In electrical engineering, an electrical isolation test is a direct current (DC) or alternating current (AC) resistance test that is performed on sub-systems of an electronic system to verify that a specified level of isolation resistance is met. Isolation testing may also be conducted between one or more electrical circuits of the same ...
A leakage current test is an alternative to the insulation resistance test. A deficiency of the insulation resistance test is that the DC voltage will not activate electromagnetic switches or internal relays etc. that are common in many modern power tools, computers, and TVs, etc. and therefore it can only test the appliance up to those components.
Automatic test equipment, any apparatus that performs tests using automation; Built-in test equipment, passive fault management and diagnosis equipment built into airborne systems to support maintenance; On-board diagnostics, test equipment for automobiles; Transistor tester, used to test the electrical behavior of transistors and solid-state ...
Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system.It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again.
