There was a hard, universally used pass-fail criterion for the Eddy Test, and a second chance was normally never allowed. Eddy described the test as having questions with multiple-choice answers, with each of the answers giving some indication of the test-taker's mathematics/physics knowledge, creativity, reasoning ability, and general aptitude.
In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker ) across the chosen path.
In electrical safety testing, portable appliance testing (PAT inspection or PAT testing) is a process by which electrical appliances are routinely checked for safety, commonly used in the United Kingdom, Ireland, New Zealand and Australia. In Australia and New Zealand it is commonly known as Test and Tag.
A lineman wearing equipment for hot glove work. In electrical engineering, live-line working, also known as hotline maintenance, is the maintenance of electrical equipment, often operating at high voltage, while the equipment is energised.
In electrical engineering, a dielectric withstand test (also pressure test, high potential test, hipot test, or insulation test) is an electrical safety test performed on a component or product to determine the effectiveness of its insulation. The test may be between mutually insulated sections of a part, or energized parts and ground.
An insulation resistance test (IR test) measures the electrical resistance of insulation by applying a voltage between two locations, and measuring the resultant current flow. Proper safety precautions must be taken when doing this test, such as exclusion zones, making sure no wires are exposed, and personal protective equipment is worn.
Maintenance testing is a test that is performed to either identify equipment problems, diagnose equipment problems, or confirm that repair measures have been effective. It can be performed at either the system level (e.g., the HVAC system), the equipment level (e.g., the blower in an HVAC line), or the component level (e.g., a control chip in the control box for the blower in the HVAC line).
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.
