Modern digital technology and safety current limitation for unproblematic workspace designs.
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.
