The test port must be blank-flanged for this measurement.
1. Select "Standby > Utilities > Check internal calibration leak".
The display shows the question: "Test port blank-flanged?"
2. Check whether the test port is blank-flanged. If the test port is blank-
flanged, continue to the next step.
3. Press "Yes".
4. Press "START/STOP" to start the measurement of the internal calibration
leak.
The evacuation is initiated; the measurement of the internal calibration
leak begins.
The display shows the measured calibration leak value.
The default value for the internal calibration leak (TL value) is also
shown.
5. Cancel the measurement of the internal calibration leak with "Cancel".
If the measured value deviates from the target value, calibrate again.
Influences such as temperature or air pressure also have a minor effect on
the results of the measurement of the internal calibration leak. Even if the
absolute accuracy of the measurement system cannot be guaranteed, you
can use the measurement results of the internal calibration leak as a refer-
ence.
6.5 Measuring
6.5.1 Measuring in "Vacuum" operating mode
1. Connect any required accessories or equipment.
Remove the blank flange on the test port and establish the connection
with the test object.
2. Check whether the parameters shown in the "Standby" window apply.
The device is ready if the display shows the "Standby" window after the
run-up of the device.
Ensure that TITANTEST™ is set to "Vacuum" operating mode.
3. In order to achieve the most precise possible measuring results, allow
the device to warm up for approx. 30 minutes (
see Chapter 6.1: "Switch-
ing on the device", page 21).
Risk of injury from suction on test port flange.
