Software Structure

Scale Transactions

Scale transactions
The software will simulate 1st and 2nd weighing operations for new trucks or known trucks, and will generate a complete weighing record upon completion of each transaction.



Upon completion of weighing sequence the software will automatically produce a weigh ticket, customized according to the customers’ needs.

Custom reports
