Appendix A: Vac Sensor Test Values Record
The leak rate for each interstice will affect the ‘Time to No Vac’, which is the time it would take for the vacuum to be
lost if the STP did not turn on to replenish it. However, the smaller the volume, the greater the impact of a small
leak on the ‘Time to No Vac’. A general guideline is to eliminate any leaks so that the ‘Time to No Vac’ reads 100
hours, which is the maximum displayed value.
Use the chart below to record Vac Sensor test values.
