2. Apply a zero reference pressure (0.00 PSI) to the P1 pressure transducer of ERX350.
Wait for the pressure reading displayed on the Pressure 1 dialog box to stabilize.
3. After the reading stabilizes, click Average Pressure Now.
MasterLinkR515 & MasterLinkSQL averages the reading and displays the average pressure.
4. Click Change.
The Change Pressure Calibration Value dialog box appears.
5. Change the value to accurately match the zero reference pressure applied to the pressure
transducer.
6. Click OK.
7. Click Span Calib.
The Pressure 1 Span Calibration page appears.
8. 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.
