A blackbox test dummy) is used for daily regular testing of the test device, which is connected to the test device. A check is made to see whether the measured values determined by the test device blackbox the values of the blackbox . If this is not the case, the test device is blocked. The device is only released for use again once a black box test has been result with result correct result . As we only supply digitally evaluating test devices, we do not usually perform this test with a "blackbox,blackboxbut instead use only a blackbox evaluate the resulting measured values within narrow tolerance limits.

If a blackbox ends with an N.test result not GO), the test device is locked. In this case, the cause of the deviation measured values must be found and eliminated. Only with atest result GO) is the test device released for use.

The timing of the black box test can be configured differently for each test device. This can be time-controlled or quantity-dependent. As a rule, the blackbox is performed after the test device is switched on.

Each blackbox of a connection option to the test device and one or more precision resistors and/or inductors. It can be designed for either one test method combinations of several test methods.

To enable correct setting of blackbox, each blackbox is calibration certificate blackbox the resistance values and a calibration certificate .

The blackbox complies with the harmonized European procedure for factory monitoring and inspection according to CIG 021 and CIG 023.
CIG 021: Factory Inspection Procedures – CIG 021 specifies how inspections are to be carried out.
CIG 023: Factory Inspection Report – CIG 023 documents what was found during the inspection.
