Methods In the conventional internal quality control in the control specimens after the test day, a specimen which total protein result was 60-80 gL^(-1), and albumin result was 30-50 gL^(-1) was selected from the first ten specimens every day, the specimen's TP and ALB results were retested after 3 hours. The difference between the two test results and the difference of the standard deviation were calculated every day for 40 days. Extreme difference quality control chart was established by control limits of range which was calculated by the standard deviation.

The main character of this control is to set the sheet gauge calculated by bounce formula as practice gauge which is compared with the setting gauge or lock gauge. The difference is the gauge difference value and is regulated by screw-down system. In such a way, the character of this system is increased and avoids the influence of such factors as roll wearing, roll heat expansion and so on. Therefore, it can greatly increase the accuracy of sheet gauge.
