Monitoring Lamp Performance from the Xcalibur Data System
With use, the deuterium lamp emits less and less light. To monitor the performance of the
PDA detector’s lamps, follow these procedures:
1.
“Preparing the PDA Detector to Monitor Lamp Performance,”
on this page

To prepare the PDA detector to monitor lamp performance
1. Open the Accela PDA Direct Control dialog box (see
“Opening the Accela PDA Direct
).
2. Make sure that the lamps are on and equilibrated:
a. Click the
Configuration
tab.
The Configuration page appears (see
b. Check the status and usage of each lamp.
c.
If they are not already on, turn on both the deuterium (D2) and tungsten (W) lamps.
d. Wait one hour for both lamps to equilibrate.
Creating a Display Method to View Light Intensity
To adjust the attenuators and monitor the status of the lamps, create a display method. You
cannot use a display method to acquire sample data.
Intensity display methods have a .spda file extension. The data system’s auditing feature does
not track the creation and modification of intensity display methods.

To create a display method
1. Open the Accela PDA Method page:
a. In the Xcalibur Roadmap
view, click the
Instrument Setup
button.
The Instrument Setup view appears.
b. In the view bar, click the
Accela PDA
button.
The Accela PDA Instrument Setup view appears with the Accela PDA Method page
