Quarterly Dust Monitor Testing

FAMIS 18393 and 23737 (as I was late to testing earlier this year)

Corner Station

LVEA

DM5 - HAM2: Has been turned off for O4 as it is not a pump-less monitor

DM6 - HAM6: Failed both zero-count and flow rate tests; has since been replaced (alog 68592)

DM10 - BSC1: Flow rate 2.8 lpm, passed zero-count test on second try

PSL

PSL101 - Laser Room: Flow rate 2.8 lpm, passed zero-count test

PSL102 - Anteroom: Flow rate 2.8 lpm, passed zero-count test

Handhelds (CER)

HH1: Makes startup/shutdown noises, but screen does not turn on

HH2: Flow rate 2.8 lpm, passed zero-count test (handheld has a VERY short battery life)

HH3: Flow rate 2.8 lpm, passed zero-count test

HH4: Flow rate 2.8 lmp, passed zero-count test

HH5: Flow rate 2.8 lpm, passed zero-count test

Others

Diode Room: Flow rate 2.8 lpm, passed zero-count test

Optics Lab: Flow rate 2.8 lpm, passed zero-count test

Vac Prep Lab: Flow rate 2.8 lpm, passed zero-count test

Outbuildings

EX - VEA: Flow rate 2.7 lpm, passed zero-count test on second try

EY - VEA: Flow rate 2.8 lpm. passed zero-count test

FCES - HAM8: Flow rate 2.5 lpm, passed zero-count test (I was told after this test that the flow rate can be adjusted; I did not do this, but the monitor was running stably, so I don't expect this needs replacing)
