The galvanic isolation protects the components of the AVL DITEST Scope from shorts caused by electrical breakdowns and ground loops. This prevents ground loops when measuring on grid-connected points (e.g. socket) and on the PC. Defect components in the vehicle or instrument are thereby excluded.

During fault finding a battery charger is connected to the vehicle and the PC is connected to a plug socket. Through the grounded electrical connections of the charger and the PC, with traditional instruments, a ground loop can be established, which can lead to incorrect measurements or may cause damage to components. This is prevented from happening with the galvanic isolation.

You can, for example, measure the battery voltage on channel 1 whilst measuring the lambda sensor-heater’s voltage supply on channel 2. The combination of non-differential measurement channels and incorrect polarity would result in short circuit. This is prevented with the AVL DITEST SCOPE SERIES.
