To Perform An Initial Lineator Test:
1. From the QA Dose Calibrator menu, touch <Linearity Testing>. The Linearity Testing
screen
is displayed.
2. Touch <Lineator Initial Test>. The Lineator Initial Test screen is now displayed.
• Touch <Back> to return to the Linearity Testing screen.
• Touch <Select Detector> to select a different detector, if multiple detectors
are connected.
• Touch <Select Max Activity Level> to toggle between maximum activities
of less than 55 mCi and greater than 55 mCi.
NOTE: The system defaults to less than 55 mCi. If your test starts with an
activity greater than 55 mCi you must select this range. Some states allow
linearity to stop at values
greater than 10 µCi.
• Touch <Zero Background> to zero the background reading if necessary.
3. Place the Tc-99m vial into the Lineator Tube 1. Place Tube 1 into the detector. The activity
for Tube 1 is now displayed as a live reading.
4. Once the reading has stabilized, touch <Record Reading>. The reading for Tube 1 is recorded
and the line for Tube 1 & 2 is now displayed as a live reading.
5. Touch <Record Reading> to record the reading for Tube 1 & 2.
6. Continue taking readings by touching <Record Reading> after each new tube or set of tubes
is placed in the detector.
7. Touch <End Test> to end the test.
8. Touch <Save Data> to save the test just performed. The Save Lineator Initial Test data

staff member, the system will default to that person on the save Lineator Initial Test
screen.) Then touch <Save Data> again to save the data in memory.
10. Touch <Enter> to select and return to the save Lineator Initial Test data screen.
11. Touch <Save Data> to save the data.
• Touch <Back> twice to return to the Linearity Testing screen.
• Touch <Measure> to advance to the Measure screen.
• Touch <View Data> to view the linearity tests stored in the system.
