A verification test must be carried out regularly for each series production. The test box simulates faults for all important safety tests. In contrast to calibration, the verification test takes only a few minutes. Like the tester and the testing system, the test box itself must be calibrated at least once a year.
The test verification boxes of SPS electronic are used for periodic inspection of all standard equipment and test systems in terms of their functionality. For this purpose, the test box is connected to the tester instead of the DUT and an "OK / DEFECTIVE" simulation is conducted. Only with a daily test can it be assured that your products work properly in terms of safety and avoid expensive recalls in the worst case.
Each test box consists of a connection option for the tester and one or more resistors and/or inductors. The test verifications boxes of SPS electronic are of high quality and available in different versions.
