Pa/s
Differential pressure (
ΔP) per second.
ΔP at the end of a stage is divided by the stage timer in second (Time average).
Pa/min
Differential pressure (
ΔP) per second.
ΔP at the end of a stage is divided by the stage timer in second and multiplied by 60
(Time average).
*Pa/s
Differential pressure (
ΔP) of the last second in a stage.
* is prefixed to distinguish from the Pa/s above.
Be sure to disable all the compensation features when using this unit.
*Pa/min
Differential pressure (
ΔP) of the last second in a stage multiplied by 60.
* is prefixed to distinguish from the Pa/min above.
Be sure to disable all the compensation features when using this unit.
