NOTES:
[1]	This pressure applies to sensor probe and adaptor assembly.
[2]	Maximum working pressure may be limited by helium source.
[3]	Source pressure should be at least twice the peak pressure but not more than 10 times the lowest pressure
[4]	Resolution dependent on range setting and cable length used in charge system.
[5]	With helium flow.
[6]	Zero-based, least-squares, straight line method.
