Appendix D Optimizing the CANBERRA iSERIES for Air Sample Counting

The GAIN Calibration should only be necessary in the event of:

•

Change of Hardware

•

System Master Clear with no restorable personality file available

•

Radon compensation issues not resolved following the recommendations
included in this application note

When performing the gain calibration, the

SOLO (or

MATIC) automatically adjusts

the gain so the upper edge of the Am-241 peak falls in channel 136 using a successive
approximation routine. Figure 8 shows the spectrum from a typical Am-241 standard.
