alarm handler is beeping about H1:PEM-CS_DUST_LAB2_300NM
We're getting <HIHI, MAJOR> alarm about H1:PEM-CS_DUST_LAB2_300NM_PCF, which I cannot trend using NDSCOPE, but I can plot H1:PEM-CS_DUST_LAB2_300NM_RAW and that number has been 30[V?] for the past 6 days.
I've silenced it but could somebody check?

Not sure why this would be alarming today, it has been invalid for many weeks. The 0.3um raw counts went from 0 to 30 last Sunday 15:34 22mar2026, but it looks like the calibrated counts-per-cubic-foot has been NAN or INF for a very long time, which is why it cannot be trended with ndscope.
Perhaps the alarms system was recently restarted and DUST2 is regularly acknowledged on startup?
