9. Click Continue.
10. In Select Ion Chamber, select the chamber with the calibration you will use.
11. Click Continue.
12. In Temperature & Pressure, enter the measured temperature.
13. Enter the measured pressure.
14. Click Continue.
15. In Calibration Conditions, select the photon reference field.
16. Select SSD Setup or SAD Setup.
17. If electron calibration is planned, select AAPM TG-51 (1999) or AAPM Report 385 (2024) under Electron Protocol.
18. If electron calibration is planned, select the electron applicator.
19. Click Continue.
20. In Reference Data Set, select the scan data set that supplies PDD or TMR values when you intend to use one.
21. Click Continue.
22. In Summary, review every selection.
23. Click Done.

Quadrant selects the new data set and opens its Equipment page.

Use Quick Add

From a data-set page, click the data-set breadcrumbs to open the selector and choose Quick Add. Use Quick Add when you want to create the record first and complete the remaining setup from the TG-51 pages.

Quick Add includes:

• Select Linac
• Select Electrometer
• Select Ion Chamber
• Calibration Conditions
• Summary

It does not include Temperature & Pressure or Reference Data Set. Complete those pages before entering calibrations that depend on them.

Both creation paths include Electron Protocol under Calibration Conditions. AAPM TG-51 (1999) is the default. Read Understand TG-51 Protocols and Saved Evidence before selecting AAPM Report 385 (2024).

Confirm the Result

After creating or selecting a data set:

• Confirm the header shows the expected institution, machine, and data-set name.
• Review all five setup pages.
• Confirm the equipment has active calibration information.
• Save setup changes before adding or editing photon or electron calibrations.
