Calibration Setup
Connect the Integritest Exacta inlet tubing to the instrument and to a regulated compressed
gas (nitrogen or air) source.
Set the inlet gas pressure to 100 psig (689kPa).
Note: For an internal calibration, external tubing is not required and valves need not be
closed.
Calibration Procedure
1. From the Main Menu Screen, click to access the Setup-Calibration Screens.
2. Click Tab F3 to open the Pressure Calibration Screen.
3. Click to start an internal calibration.
4. The instrument will automatically begin to collect data for each calibration pressure.
5. As the internal calibration terminates, pressure will be released.
6. The calibration coefficients 1, 2, 3 and the regression coefficient for the secondary
transducer and pressure regulator will be updated automatically so they are matched
to the Primary transducer and appear on the screen. The information for the Primary
transducer is not adjusted.
7. When the test is complete, print the report by clicking on the Print Icon .
