FT of M1605-M1608 |
|
|
Only M1607 graded B. All others are graded C due to trimbit test.
M1606 should be looked carefully and may be retested since the threshold after trimming has strange features
(although not for all temperatures) that may mean that some trimbits really do not work.
Other modules to be re-analised without results of trimbit test or upgrade manually, since these results
are due to test algorithm. After trimming the threshold looks good for all failed ROCs. |
