| Zusammenfassung: | Several assemblies have test voltage points connectable to the equipment high resistance voltage testing device which delivers a defect signal when the voltage at the test point is incorrect. Test points of a number of assemblies have the same nominal voltages, generated possibly by additional voltage dividers. The voltage testing device can be connected by a selector switch to each assembly. Alternatively, it is connected to the test points by a scanning head. The output of the differential amplifier is connected to two photodiodes. |
