When choosing the correct gauge PSI option for your seat pressure, keep in mind that you never want to exceed the gauge limit as it can damage the gauge. Per the specifications of the gauge manufacturer, the most accurate testing location is the middle one third range on the gauge. For example, if your seat pressure is between 250 and 350 you will want the 600 PSI option.
