Using a second tab in the KeyLAB test workbook is a way to keeping the sheet neat and tidy by keeping the calculation hidden. There is a major area which this could cause a problem. This is when you have a graph on a sheet which you are printing. It can appear to print the data for the first for all the sheet you print. This applies to input and output sheets.
So you have 3 tests with a calculation tab. When you batch print them you will get the graph on the first page working correctly then on the second and third the graph will be identical to the first page but all the other data on the sheet will have changed.
This is caused because of the way that KeyLAB print multiple tests. To fix the problem you will have to make the data which the graph uses available on the main tab. Once this is done the problem will stop..
