5) Tighten the chamber screws lightly, bottom screw first. When the three screws are in place,
tighten them securely, but
6) Reconnect the Alpha module to vacuum, USB, and power; slide the unit back into its enclosure;
and tighten the eight front-panel Phillips screws. Reapply mains power to the enclosure.

TROUBLESHOOTING

When installation is complete, users should be able to start up MAESTRO or AlphaVision, go to the
detector pick list in the program, and select the spectrometers (two inputs per Alpha Duo, one per Alpha
Mega) that was configured during setup.

Can't fine the Duo or Mega on the Detector Pick List

Make sure the Alpha module or Ensemble is powered on.

the module. The battery is located on the upper-rear quadrant of the PWB. Contact ORTEC for the
appropriate replacement.

Resolution Problems

Severe degradation in peak resolution can destroy an alpha spectrometer's ability to make meaningful
measurements. Apparent degradation of resolution may be due to one or more causes:
Poor vacuum – Check the chamber pressure reading.
•
Excessive electronic noise – Examine the pulser peak resolution and detector leakage current
•
compared to that specified on the original detector quality-control sheet. Sometimes a noisy
detector can be restored by the simple act of removal and replacement, which reseats the
connector pin. If detector substitution demonstrates the problem to be in the electronics, contact
the Global Service Center.
