In addition to the daily verification tests, the tester and the testing system should be checked at regular intervals with calibration resistors. This is not a calibration of the testers and the testing systems, but may well be an important part in a quality system. In contrast to the verification test, both the function of the testing equipment and the measuring system is tested. The calibrator and calibration resistors will be supplied with a factory calibration or DAkkS document and are available in different versions.
