A master has two black contracts, both of which have an A3 and A4 meter. The contract also has a minimum volume of 20,000 pages per month. A3 prints count for 1.5 A4 prints.
The master was set up with an A3 and A4 master meter. A Total Black (Calculated) meter was also included, but not set to be a master meter. Similar to a standalone contract, the Total Black (Calculated) meter was set to be non billable, so that it charges standard billing at $0.00 (as the standard amounts are billed on the child contracts). Unders, overs and minimum volume were put on this Total Black (Calculated) meter. The A3 meter was also specified to have an A4 Ratio of 1.5.
The master setup is as follows:
The contracts only receive the black and black A3 meter reads:
The first contract receives a read of 31,000 for A4 and 6,000 for A3. The second contract receives a read of 55,000 for A4 and 8,000 for A3.

The second child contract job:
The master contract calculates that there were effectively (6,000 + 5,000) + 1.5 X (2,000 + 1,000) = 15,500 pages. The master then bills 4,500 under pages to make up the minimum volume of 20,000.
