Tariffs can have the option to set a quarantine period. During this period, new purchases will be calculated from the first purchase that activated the quarantine period. The quarantine is calculated per vehicle and Zone.
This is used where tariffs have e.g., the first hour free to prevent re-using that free hour over and over again.
After checking the quarantine check-box you can select quarantine for 1 day or for a specific number of hours.
