Oscillation
Maximum oscillation under all circumstances:
Tap sensitivity of outlet pressure set point
For all gases the maximum deviation may be 1 mbar.
Repeatability of outlet pressure set point
For all gases the maximum deviation from set point is:
mbar or 3% of the set point value, whichever is the greatest.
