Galvanic isolation between AVL DITEST SCOPE and PC

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.

An example

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.

Differential measurement channels

The differential measurement channels allow measurement with 40 MS/s and the full bandwidth. Each channel is independently available from the others – so current, resistance and voltage measurements can be carried out in parallel. Short circuits and incorrect readings during the measuring process are thus ruled out.

Tips from the workshop

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.
