  2. Battery tester - Wikipedia

    en.wikipedia.org/wiki/Battery_tester

    Battery tester. A battery tester is an electronic device intended for testing the state of an electric battery, going from a simple device for testing the charge actually present in the cells and/or its voltage output, to a more comprehensive testing of the battery's condition, namely its capacity for accumulating charge and any possible flaws affecting the battery's performance and security.

  3. Electrical isolation test - Wikipedia

    en.wikipedia.org/wiki/Electrical_isolation_test

    The test often reveals problems that occurred during assembly, such as defective components, improper component placement, and insulator defects that may cause inadvertent shorting or grounding to chassis, in turn, compromising electrical circuit quality and product safety. [2]

  4. Accelerated life testing - Wikipedia

    en.wikipedia.org/wiki/Accelerated_life_testing

    In any case, the parameters would be related to the test subjects and the levels of the stress factors being tested. As a simplified example, consider a test object with a life distribution that roughly matches a normal distribution. Tests at various stress levels would yield different values for the mean and standard deviation of the distribution.

  5. Multimeter - Wikipedia

    en.wikipedia.org/wiki/Multimeter

    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.

  6. Battery holder - Wikipedia

    en.wikipedia.org/wiki/Battery_holder

    Battery types such as the 9-volt have snap-on contacts. Battery holders for zinc-air batteries must not be completely air-tight since approximately 1 litre of air is required per ampere-hour of discharge per cell. The battery holder may include a valve integrated with the device power switch to allow air to be admitted when the device is ...

  7. Highly accelerated life test - Wikipedia

    en.wikipedia.org/wiki/Highly_accelerated_life_test

    Many accelerated life tests are test-to-pass, meaning they are used to demonstrate the product life or reliability. It is highly recommended to perform HALT in the initial phases of product development to uncover weak links in a product, so that there is better chance and more time to modify and improve the product.

  8. Test probe - Wikipedia

    en.wikipedia.org/wiki/Test_probe

    A test probe is a physical device used to connect electronic test equipment to a device under test (DUT). Test probes range from very simple, robust devices to complex probes that are sophisticated, expensive, and fragile.

  9. Lithium polymer battery - Wikipedia

    en.wikipedia.org/wiki/Lithium_polymer_battery

    Test reports warn of the risk of fire when the batteries are not used per the instructions. [12] The voltage for long-time storage of LiPo battery used in the R/C model should be 3.6~3.9 V range per cell, otherwise it may cause damage to the battery. [13]
