What are the types of test used to verify the correct functioning of electronic equipment?

1. To test the functionality of a piece of electronic equipment, calibration tests can be performed in various ways. For example in equipment with variable outputs that are not calibrated (some power supplies), a test using a multimeter or oscilloscope (obviously both being within calibration) can be performed to compare the output voltage to the measured voltage and thus adjust the variable outputs to the correct value required. For pieces of equipment that do require calibration; if the equipment comes out of calibration before the re-calibration date, calibration should be performed or organised before use.
