Did Zero Count and Flow tests on all dust monitors. Zero Counts were all OK. Flow is down a little (2.8l/m to 2.6l/m) on the dust monitor in the Biergarten and at End-Y. If flow drops any more will adjust during next months check. Made minor adjustments to the air bypass on all three vacuum pumps to bring the flow rate back to 19 inHg. All temperature check were within normal range.
