Enter Temperature and Pressure

Use Temp / Pressure to record the environmental conditions measured during the calibration. Quadrant uses them to calculate C_tp.

Enter the Measurements

1. Open Calibration > TG-51 > Temp / Pressure.
2. Confirm the selected TG-51 data set.
3. Enter Temperature (°C).
4. Enter Pressure (mmHg).
5. Review Ctp (calculated).
6. Click the calculated value when you want to inspect the equation and substituted values.
7. Review the pending changes.
8. Click Save.

Correct a Pending Value

When an entered value differs from the saved value, Quadrant shows the previously saved measurement. Click Restore to return that field to the saved value.

Changing either measurement updates C_tp immediately.

Caution

Temperature and pressure affect the corrected chamber reading. Confirm the units and measurement time before saving.

Existing Calibrations

If the data set already contains calibrations, saving new environmental conditions can open a recalculation preview. Review the affected energies and the old and new results before choosing Recalculate & Save.

Confirm the Result

After saving:

• The change count disappears.
• The environmental values remain visible.
• C_tp reflects the saved temperature and pressure.
• Any accepted recalculated values appear in the photon or electron tables.

Continue with Set TG-51 Calibration Conditions.
