Apply a high pressure such that the pressure applied is at least 50% more than the zero reference
pressure.
Wait for the pressure reading displayed on the Pressure 1 dialog box to exceed the zero reference
pressure by 50%. For example, if the zero reference pressure on a 100 PSI transducer equals 0.00
PSI, then the span reference pressure must be between 50.00 and 100.00 PSI. If the zero reference
pressure on a 600 PSI transducer equals 0.00 PSI, then the span reference pressure must be
between 300.00 and 600.00 PSI.
l
After the pressure stabilizes, click Average Pressure Now.
MasterLink Software Application SQL averages the reading and displays the average pressure.
