Bind Height and Open Height Ht for Force is the force that is produced at a particular spring height that you can specify in the Test Options screen Open Velocity is rate in feet second at which the operator compressed the spring during the test Close Velocity is rate in feet second at which the operator released the spring during the test Cycle Time is the total time in seconds from start to finish of cycling the spring during the test Figure 3 4 Definitions of Various Spring Heights Retainer shown for these 3 heights to indicate these are heights related to the spring installed in the engine Installed or Open Height Bind Height Seated Height spring height spring height spring height with at full valve lift fully compressed valve closed on Its seat Max Valve Lift Bind Clearance not a calculated output but just shown for information 46 C Performance Trends Inc 2003 Valve Spring Tester Chapter 3 Output Notes If you have selected the Spring Height Format of Compression from Seated Ht not Free Spring Height on the main screen then Open Height Seated Height and Bind Height are reported as heights measured from Seated Height and the more the spring is compressed the higher the compression number These velocities and times should not have a significant effect on the results However if an operator is doing the test very quickly for example the electronics may not be able to record enough data
