This function is used to measure the pressure of the air conditioning system during operation. This
means you have the possibility to control the high pressure and low pressure side during operation.
The procedure starts with a pre-filling of the hoses with CO2. This ensures the lowest possible loss
of refrigerant from the air conditioning system of the vehicle. The minimum bottle pressure must not
be less than 50 bar. You will then be asked to turn on the air conditioning system of the vehicle.
Confirm this on ADS 340. The procedure must be terminated by the user.
