A test light, test lamp, voltage tester, or mains tester is a piece of electronic test equipment used to determine the presence of electricity in a piece of equipment under test. A test light is simpler and less costly than a measuring instrument such as a multimeter, and often suffices for checking for the presence of voltage on a conductor ...
Memory built-in self-test (mBIST) - e.g. with the Marinescu algorithm [2] Logic built-in self-test (LBIST) Analog and mixed-signal built-in self-test (AMBIST) Continuous built-in self-test (CBIST, C-BIT) Event-driven built-in self-test, such as the BIST done to an aircraft's systems after the aircraft lands. Periodic built-in self-test (C-BIT/P ...
Analog multimeter Digital multimeter. A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [2] [3] A typical multimeter can measure voltage, resistance, and current, [4] in which case can be used as a voltmeter, ohmmeter, and ammeter.
An insulation test set; in this pattern, a hand-cranked generator provides the high voltage and the scale is directly calibrated in megohms. Voltage withstand testing is done with a high-voltage source and voltage and current meters. A single instrument called a "pressure test set" or "hipot tester" is often used to perform this test.
IEC 60068 is an international standard for the environmental testing of electrotechnical products that is published by the International Electrotechnical Commission (IEC).. IEC 60068 is a collection of methods [1] for environmental testing of electronic equipment and products to assess their ability to perform under environmental conditions including extreme cold and dry heat.
An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component. [1] In the simpler versions of this instrument the impedance was measured internally and converted for display to the corresponding capacitance or inductance value. Readings should be reasonably ...
