Entering correction factor in total pressure measuring and control unit
► Enter the correction factor to correct the displayed measured value.
Calculating pressure for gases other than air
► Calculate the effective pressure using the following formula:
P
eff
= C × p
● P
eff
= Effective pressure
●
C = Correction factor
● p = Displayed pressure (gauge calibrated for air)
