Verify that no channel turns on. Feed information into global list of problems. Software to do scan exists, works. Software to report problems does not exist yet. Feed information into global list of problems.
Software exists, works.
Can also be used to quickly find dead channels. On earlier version of the chip, pinholes could also clearly be seen in this test. On bonded detector. No hardware in PI, as far as I know. Then there are other things that we probably want to check, but for which I do not have a clear picture of the testing procedure.
