Traditionally, on/off valve controls forced the end user to compensate for the difference in time between when a dispense valve turns on or off and the corresponding point at which material starts or stops on a substrate. Now, through a simple calibration procedure, this concern is another that is relegated to the history books. The calibration procedure helps the end user make a one-time measurement of the time and distance between valve "on" and the start of the gasket as well as the valve "off" and the end of the gasket. Now it does not matter if you are dispensing at 1"/second or even 20"/second, the gasket will start and stop at the programmed points.
