No glitches found last night, which used to come from the DACs of ETMY

The sampling frequency of ETMY model was changed (4269), and we left ~ 1000 cnts DC offsets applied to the MN stage before we leave the office last night.
There were no glitches last night (see the attached), except for the one probably due to an earthquake at Papua New Guinea.
Unfortunately some fraction of data is lacking on Data Viewer, but we can say that the rate of the glitch dropped by far.

We still don't know why, but decreasing samplig frequency to 2 kHz works for this issue.
