Depends on what it says on the test strip containers or maybe the control solution container.
For example with my Accu-check Expert it comes with two control solutions (numbered 1 and 2) and on the test strip containers it states what ranges it should show for the each control solution. For my TrueYou meter it has 3 ranges for control solutions.
Edit:added picture for clarity
As you can see each control solution has a number (1 and 2) and on the side of the test strip bottles is the range for each numbered solution - so 1.7 to 3.3 for number 1 and 14.1 to 19.1 for number 2
