Calculation of the SF
for using the pressure gauge (tool)
Write down the result measurement into the corresponding box :
Measure the atmospheric pressure in MPa. A
Measure the ambient temperature in C. B
Transfer the values into the corresponding box and write down the result :
With the help of the table (page 4) "Values of the SF
effective pressures in accordance with the temperature",
determine the value "p
Value of the reference atmospheric pressure in MPa D 0
Transfer the value of the local atmospheric pressure
Calculate the difference of the atmospheric pressure
Calculate the rated effective pressure
The filling with SF
to the calculated pressure, plus 0.01 MPa,
