Dear friends:
I have a problem with a Norland Bone Densitometer.
This is a Eclipse bone densitometer from Norland.
When I try to do the QA, very soon gives me a message that the discriminator settings are out of place or something to that effect.
I have done the gain calibrations and being the numbers correct still gives me the same message.
The only thing I can tell is that the first "hump" that should be there on the high energy PMT is not there. I believe that the high energy PMT is not performing as it should.
Can anybody give me a hint?
Sincerely:

Filter, High PMT or PMT amplifier may be the problem. Messurements on PMT amplifier
