Power outage yesterday must have knocked it off again. de 2008-02-15T23:58:06Z 15 Feb. Started humidifier. de 2008-02-21T19:07:45Z ccn computer locked up, saying low on virtual memory, restarted humidifier, added butinol to cpc 2008-02-27T18:02:53Z ccn computer locked up again "low on virtual memory" reboted. 2008-03-03T17:09:24Z ref neph lamp off 2008-03-04T19:39:51Z bch 4 MAR 1935Z Replaced dry neph lamp- 2008-03-06T19:15:13Z bch approx. 1830-1930Z 6 MAR 2008 large CNC spikes due to snow blower working in clean air sector, clearing road out to Point Barrow- 2008-03-11T01:07:16Z bch CCN counter ran out of water over weekend, 8-9 MAR 2008; shut down data acquisition program and restarted on 11 MAR at 0053Z - 2008-03-12T22:53:35Z bch 12 MAR 2008 CO2 tank pressure 800 psi - 2008-03-19T19:52:26Z bch 19 MAR 2008 Neph. span check 1950Z; CO2 tank pres. 710psi flow 8 lpm - 2008-03-20T23:36:50Z adjusted spareline rotameter to read 30lpm (was 20 lpm), adjusted T/RH rotameter to read 30 lpm (was 50 lpm) ; EJA 2008-03-20T23:37:15Z further pumpbox work will await me changing into warmer clothes! 2008-03-20T23:53:12Z There is a nafion drier in the CN box. will remove or bypass to see if that helps CN counts as suggested. 2008-03-21T00:09:03Z beginning nafion drier removal. cpc wil be sampling lab air soon. 2008-03-21T00:10:24Z cc wow lab air is clean!! only 80 2008-03-21T00:22:05Z pulling CN box cuz can't get drier out without doing so. while CN box is out will clean CN orifice. (probably won't reinstall CN until tomorrow.) 2008-03-21T01:14:03Z CN drawer will stay out over night. Need my supplies and they aren't here yet. have plumbed in piece of conductive tubing in place of nafion drier assembly. 2008-03-21T01:15:20Z i think this replumbing means that the flow through the CN line from top of tower to CN will only be 1 lpm. please advise if i should set up extra flow for CN line 2008-03-21T03:53:36Z reinstalled cpc. have taken out nafion drier. and cleaned orifice. liquid light is back on (was off when i got here though lots of buOH in instrument. 2008-03-21T03:55:00Z counting lab air still. counts are now 180/cc (were 80/cc before treatment). have not recalibrated flow yet. 2008-03-21T03:57:03Z sampling outside air now. note: instrument is not warmed up yet so counts may not be valid. 2008-03-21T03:59:43Z cpc sampling room air again 2008-03-21T04:00:47Z sampling outside air 2008-03-21T04:33:02Z ignore cpc flow up til now since last message. i plumbed so there was flow through drier line too - to increase flow through long bit of 1/4" tubing up stack. 2008-03-21T04:34:00Z the drier flow rotameter is pegged though so it might be sucking more particles than the cpc. still seeing less particles than ccn. 2008-03-21T04:34:32Z will put back to 1 lpm through line only 2008-03-21T04:41:16Z ok back to flow straight from top of tower into cpc. will leave like this overnight. 2008-03-21T16:25:28Z CN counts currently higher than CCN. wind shifted so from contaminated sector. note low cloud perhaps slightly above stack. 2008-03-21T16:27:35Z hmm no comms on cpc. checking serial cable 2008-03-21T16:29:38Z well weird - cn window says no comms but the values are changing. serial cable is fine of course. 2008-03-21T16:48:38Z removing cpc box from rack to do replumbing. 2008-03-21T16:49:03Z m 2008-03-21T16:50:19Z CN drier flow replumbed with critical orifice. will take pictures and draw schematic of new plumbing. 2008-03-21T17:19:45Z cleaned filter holder for PSAP and replaced o-rings. knob holding filter holder was not on, but there isn't enough screw to hold it on. 2008-03-21T17:21:20Z let me know if absorption values look wacky. not sure right now how good seal is in filter holder. 2008-03-21T17:38:57Z installing new HEPA filter on wet neph 2008-03-21T22:50:18Z system now running on new cd and new usb stick. 2008-03-21T22:54:15Z New version of software does not have 'aeromon' active. no 'M' in logging letters, or choice of aerosol contam in main menu. 2008-03-21T22:56:39Z also doesn't have either filter rack in the list of menu items or F&G in the list of letters. 2008-03-21T22:58:10Z will reboot from scratch and see if that helps 2008-03-21T23:14:49Z so when i rebooted i watched messages scrolling. one was about filter iptables. i took a photo so i will email the mesage to derek 2008-03-21T23:15:23Z mean time i will put old CD back in to see if we get the filters and contamination stuff back. 2008-03-21T23:25:16Z new stick, old cd. still no filters or contam menus. 2008-03-21T23:25:42Z will reboot one more time, this time with old stick and cd. bios settings are still new ones 2008-03-22T00:04:00Z also getting best ups is failing to rotate error message right at start up. not sure if that is related or an extra perk. 2008-03-22T00:28:01Z ok filter stuf and contamination menu are back now. 2008-03-22T18:18:14Z CCN higher than CN when concentrations are low. CCN lower than CN when concentrations are high. 'high' conc seems to be slightly more than 200/cc. 2008-03-22T18:19:27Z that's just an observation based on the last couple days of CN and CCN measurements. 2008-03-22T18:25:28Z going through SMPS procedures in 'monthly checks of SMPS' description by TT. zero check first. 2008-03-22T18:35:34Z things to add to BRW checklist? SMPS CPC - laser light=lit, temp light=lit, flow light= not lit, buOH level OK. 2008-03-22T18:36:25Z Also add SMPS flow checks to periodic list of things to do. 2008-03-22T18:52:43Z SMPS zero check looks good. trying aerosol flow check next. 2008-03-22T18:53:10Z instruments fail to rotate - BestUPS error message showing up. 2008-03-22T19:02:52Z SMPS aerosol flow adjusted to 0.5lpm. 2008-03-22T19:07:56Z sheath flow is ~4.8 lpm, more than 0.1 diff from 5.0 so needs adjusting. 2008-03-22T19:23:35Z SMPS flow checks complete. Description of procedure will get some editing! 2008-03-22T21:44:20Z best ups error message is that it 'failed to flush' not that it failed to rotate. not sure which i typed earlier. 2008-03-22T21:51:28Z added water to humidifier. is pinky sticky note fill line? 2008-03-23T20:41:52Z cycling power on SMPS 2008-03-23T20:44:55Z i turned on and off both red power switches on SMPS and cycled power on the computer. not sure what the two red power switches do! 2008-03-23T21:03:06Z wiped some rime off top of tower. didn't see CN high speed line, but got too cold to look. 2008-03-23T21:34:56Z opened pumpbox to check where flow goes. diddled with rotameter that filter#2 rack goes through - it's all the way open, but i couldn't see ball 2008-03-23T21:35:19Z couldn't see rotameter ball til i messed with rotameter valve. 2008-03-23T21:36:23Z note filter#2 flow is controlled by mfc, just routed through rotameter on way to pump. 2008-03-23T21:40:12Z not sure why filters are bypassed. air is from clean sector and not contaminated 2008-03-23T21:41:27Z dp5 on filter rack#1=0. that seems strange. the quick connect seems ok. 2008-03-24T16:55:54Z filters were left in bypas mode. will unbypass now 2008-03-24T16:59:03Z hmm didn't tell the computer that filter change was done. so ..tel it i'm doing filter change and then tell it i'm done. 2008-03-24T17:02:11Z filter1 is blank. 2008-03-24T17:02:31Z filter2 started at 84.71; 2008-03-24T17:02:48Z still no dP on filter#5 on filter rack1 2008-03-24T17:16:15Z measuring cpc flow with gilibrator 2008-03-24T17:33:53Z cpc flow is 0.982 lpm=16.37cc/sec (cpc3010, s/n2452) 2008-03-24T17:34:57Z will cal psap flow next. will need to convert volumetric flow to mass flow - need lab T, ambP. 2008-03-24T18:00:08Z done fiddling with PSAP flow 2008-03-24T18:09:16Z changing filters on CN and CN drier MFC. using filters from CCN spares. 2008-03-24T18:25:07Z CN and CN drier MFC filters installed. 2008-03-24T18:25:40Z using one of removed filters for top of humidifier reservoir. one there is grungy grey 2008-03-24T19:01:59Z starting impactor servicing 2008-03-24T19:55:03Z system back on line after impactor change 2008-03-24T22:03:05Z calibrating cn mfc flow 2008-03-24T22:13:15Z done calibrating CN mfc flow, now doing CN drier flow 2008-03-24T22:44:37Z finished CN drier mfc cal. 2008-03-24T22:56:25Z stopping cpd to change back to old filter#1 settings to see if those make more sense. 2008-03-24T23:27:46Z going out to remove splitter for cleaning and inspection 2008-03-24T23:56:26Z vacuum grease and splitter and 2" pipe are pretty much frozen together. i think i will wait and see if it gets warmer later this week - windchill is -40 now 2008-03-24T23:56:56Z some lines still sampling pumpbox air though. will warm up and reattach 2008-03-25T00:17:10Z splitter all attached again. haven't cleaned. will try again if the wind stops and it warms up a little (thurs?) 2008-03-25T17:01:17Z started filter change before saying so using PSAP menu 2008-03-25T17:37:57Z There is something wierd with voltages for filter 1 (umacV) curently sampling filter 3, but filter3 voltage (channel 10) is -0.048. 2008-03-25T17:39:11Z filter2 voltage (chan9) is -0.061 and filter4 voltage (chan11) is -0.33. filter5 has been wierd since filters were changed. 2008-03-25T17:40:02Z i will ask dan about oddities with filter carousel when he gets in. 2008-03-25T18:07:29Z starting neph zero check 2008-03-25T18:10:13Z put hepa filter on inlet of ref neph. will leave on for next several hours 2008-03-25T18:20:48Z starting psap zero check. putting balston filter on inlet of psap 2008-03-25T20:16:45Z going to try removing rotameters from pumpbox for cleaning. they are somewhat gungy. will stop if seems like something will break from cold. 2008-03-25T20:17:10Z bypassing filters for now 2008-03-25T21:11:16Z done with rotameter cleaning. 2008-03-25T21:34:25Z humidograph seems to be on some sort of 1/2 hour cycle (based on cpx plots). it does the upscan but not the downscan it looks like. 2008-03-25T21:46:53Z stopping neph and psap noise checks. will let system get back to normal and then do a leak check since we changed impactors yesterday. 2008-03-25T21:48:56Z neph and psap back to sampling ambient air 2008-03-25T22:55:45Z restarting cpd to have flow cals (CN,PSAP,CN_drier) take effect. 2008-03-25T23:19:51Z i think the humidifier thermal cutout switch is turning off the humidifier heater at ~70%RH. i haven't seen any drips into the reservoir for past 10 min 2008-03-26T00:02:59Z removed restrictor and humidifier pump flows happily. cannot physically blow air through restrictor or water out of tube. could restrictor be clogged? 2008-03-26T00:39:55Z did SMPS cal with brad. 2008-03-26T00:54:02Z doing leak check cuz wind has dropped 2008-03-26T00:55:56Z c ambient counts =45 2008-03-26T00:56:23Z dpNeph=6.7 2008-03-26T01:05:24Z cpc counts=3 (ccn counts ~7); dp Neph imp=11.5 2008-03-26T01:05:51Z those were for filtered air. the hepa filter is on the stack inlet. 2008-03-26T01:12:54Z did leak check over hour so now filter is off should give ew amb counts=44/cc, neph_dp_imp=1.0 (coarse cut) 2008-03-26T01:13:28Z three-way valve back to normal 2008-03-26T01:28:48Z so not sure what to do about humidifier - constrictor seems too constrictive, but too much water flow w/o it. 2008-03-26T01:29:48Z pump was trying pump but couldn't get flow past constrictor. would this burn out pump eventualy? 2008-03-26T01:30:25Z we'll leave constrictor out over night. 2008-03-26T17:08:41Z in 24 h PSAP transmittance goes from 1.0 to ~0.75. at flow of ~2lpm. 2008-03-26T17:34:41Z quitting cpd to restart with pause=1.0 in cpd.ini 2008-03-26T17:35:40Z hmm that looks good! i see filters and contamination letters. thanks derek! 2008-03-26T17:46:02Z shutting down CCN so can replace sheath air filter 2008-03-26T18:36:54Z CCN back on line. 2008-03-26T18:46:38Z reset clock on CCN - it was saying jan 1 1999. is this a sign that the battery needs changing? 2008-03-26T20:03:45Z pulling a vacuum on filter rack#1, dpsensor#8 to see what i see 2008-03-26T20:34:56Z didn't see any response in channel 15 voltage corresponding to pulling vacuum on dP#8 in filter rack#1 2008-03-26T20:36:25Z try reseating cables for dp Sensor plugs 2008-03-26T20:42:44Z wiggle cables and reseated dpconector. dp5 briefly had a value, although voltage on channel 12 didn't change. this is very confusing. 2008-03-26T20:51:09Z voltages corresponding to dP sensors are significantly different on filter rack2 than on filter rack1 2008-03-26T20:53:08Z filter rack2 voltages make sense - they are all ~0.95 except for filter that is sampling which is ~2.4. 2008-03-26T20:53:52Z also on filter rack#2 reported dP values are 0 except for filter that is sampling. very sensible. 2008-03-26T20:54:14Z perhaps dP board is bad in filter rack#1? 2008-03-26T20:55:22Z will pull a vacum on filter rack#2 filter#8 just to see if get a response as i expect 2008-03-26T20:57:48Z dp#8 sensor on filter rack2 behaves as expected. if i suck on a tube connected to it 2008-03-26T20:59:30Z if i suck on a tube connected to dp sensor#8 filter rack#2 i can get the voltage to change from 0.9 to 1.5 2008-03-26T21:00:11Z i will look at dp board in filter rack#1 more closely 2008-03-26T21:12:06Z disconnected cable from actual dp sensor board. so voltages are nonsense. they bounce all over is that normal? 2008-03-26T21:14:52Z cable on board plugged back in and back to what it was before, i.e., not good. 2008-03-26T22:15:27Z just climbed up tower and scraped some rime off inside of stack. could have been some blocking what i think was CN inlet. 2008-03-26T22:16:59Z CCN counter has been counting quite a bit lower than CN counter since i restarted it after changing sheath air filter. 2008-03-26T22:17:49Z the note on the case says to run T1-Tsample at +3, so i put it at that. was at +2 before. not sure if that made difference? 2008-03-26T22:18:07Z i put at T1-Tsample at +2 to see what happened. 2008-03-26T22:19:10Z i'm going to detach CN sample line in pumpbox and then blow air backwards up it. that's how brad cleared a gas sampling line earlier. 2008-03-26T22:37:52Z cpc sampling lab air. 2008-03-26T22:44:59Z sampling from top of stack again 2008-03-26T23:24:33Z i am going to try using bios to calibrate Q_analyzer 2008-03-26T23:40:48Z trying bios cal of analyzer Q. 2008-03-27T00:37:21Z done flow check on Q_analyzer with gilibrator. it works it's just not very nice compared to bios. 2008-03-27T00:37:33Z starting flow check on filter1 with gilibrator 2008-03-27T00:37:40Z bypassing filter1 2008-03-27T00:55:37Z done with flow checks on filter#1 2008-03-27T00:56:16Z unbypassed filter#1, bypassing filter#2 to do flow check. 2008-03-27T01:12:09Z done checking filter2 flow with gilibrator. i finally got the hang of making nice bubbles. 2008-03-27T01:19:19Z note: since CCN and SMPS pull flow off filter#1 their measurements will be affected by the flow check i did. 2008-03-27T17:05:50Z rechecking flow on filter1 since so far off. bypassing filters in filter rack1 - note this affects CCN and SMPS 2008-03-27T17:45:52Z done with flow checking filter1, unbypassing filters 2008-03-27T19:16:27Z installling temporary RH sensor manifold downstream of humidifier 2008-03-27T19:22:35Z manifold has RH sensor downstream of wet neph, 'transfer standard sensor and aerosol rack RH sensor in it. 2008-03-27T19:35:12Z wrapped manifold in insulation. 2008-03-27T19:37:05Z will let equilibrate - swagelok fittings were cold as was insulation. 2008-03-27T19:48:09Z stopping cpd to enter flow cals for Q_analyzer, Qfilter1 and Qfilter2 2008-03-27T19:52:55Z also updated primary contacts list for BRW 2008-03-27T20:03:21Z with my new calibrations for Q_filter1 and Q_filter2 pump2 doesn't seem able to pull what is need to get 30 lpm mass flow through each filter rack 2008-03-27T20:04:14Z i will assume it is poor calibration on my part and put pat's cals from september back in. i will do that for analyzer too as if one cal is bad they all are. 2008-03-27T20:23:44Z rearranging manifold so sensors are closer. 2008-03-27T21:13:20Z got up to 80%RH using humidifier as RH generator. used to check sensor downstream of wet neph, and sample inlet RH against transfer standard sensor. 2008-03-27T21:13:45Z they both looked good. will do filter1 sensor next 2008-03-27T21:16:48Z bypassing filter rack#1 while RH sensor is removed for calibration 2008-03-27T21:50:28Z done with filt1 sensor. will remove it, unpass filt1 rack and start on filter2 rack 2008-03-27T21:55:33Z can't remove filter2 inlet RH sensor with cable from rack. it is wired directly to back of filter rack. 2008-03-27T21:56:07Z it is a new style RH sensor though, so i will remove head unit and calibrate against wet neph sensor 2008-03-27T22:05:20Z going to get RH sensor out of splitter t/rh line 2008-03-27T22:23:39Z done with filter 2 RH sensor. will replace and unbypass filters. then do stack RH sensor 2008-03-27T22:31:43Z will wait for stack RH sensor to warm up before doing cal 2008-03-27T23:16:14Z done calibrating stack sensor. will replace in stack and put things back to normal 2008-03-27T23:30:28Z everything back to normal with respect to RH sensors and plumbing. 2008-03-27T23:31:08Z it is 'relatively' warm today. i moved the snow off the exhaust filter. i am going to bring it into the garage and check it out. 2008-03-27T23:39:47Z playing with humidograph. have a 1/16" tubing as restrictor in line. 2008-03-27T23:43:09Z ok now going to take off exhaust filter. 2008-03-28T00:42:27Z stack exhaust filter is off. it needs to sit in garage over night - it looks (looking in the gazouta) like there's ice/snow in it. 2008-03-28T00:43:20Z i stuffed a bit of the blue fiberglass stuff in the tube coming out of the pumpbox, but i wouldn't necessarily trust the PSAP measurements. 2008-03-28T00:44:40Z dan has heat gun here. if exhaust filter comes apart and goes together nicely in the morning i may try to use heat gun on splitter to remove and clean it. 2008-03-28T01:10:26Z added water to humidograph 2008-03-28T16:35:43Z cycling power on CCN to recheck time issue 2008-03-28T16:40:30Z humidgraph scanning looks better with different restrictor and pump parameters (based on cpx plots) but not perfect. 2008-03-28T16:55:45Z stopping cpd to have RH cals take effect 2008-03-28T20:23:30Z DCH Restart for filter dP change 2008-03-28T21:18:38Z pumpbox filter reinstalled with new filtermat. weights lots less w/o ice in it! 2008-03-28T21:46:17Z pulling vacuum on each of the dP sensors in filtrack#2 while dan changes filters 2008-03-28T21:51:25Z now doing filter rack1 2008-03-28T21:57:46Z results from sucking. on board in filtrack#2 every voltage went from 0.9ish to something larger (1.4 -2.1V depnding on how much vacuum applied) 2008-03-28T21:58:12Z on board in filtrack#1 none of the voltages responded to sucking or pushing. 2008-03-28T22:17:52Z took pictures of CCN boards where (i think) battery is. may help for describing how to swap battery out. 2008-03-28T23:57:39Z done with annual maintenance 2008-03-30T22:16:39Z eja updated Q_CN,Q_CNdrier,Q_psap -

N81 is lab transfer N61 is SMPS cpc. 2019-09-27T19:20:40Z EJA got rid of spare tubing for former cosmos line to filter pump - now they have their own pump. (first rotameter in pumpbox not being used) 2019-09-27T19:20:50Z EJA shortening vacuum line to cosmos pump. 2019-09-27T19:27:51Z EJA cosmos tubing shortened and back to normal 2019-09-27T22:22:52Z EJA ending smps transfer comparison. plan is to leave transfer cpc in SMPS rack until we can get another 3010 CPC up here to replace it. will send current cpc back to boulder for repair and shipment to leipzig. 2019-09-27T22:24:00Z EJA so when i leave tomorrow: aerosol cpc = 2047 (same as when i came), smps cpc = 2438 (lab transfer cpc). bryan/peter will ship former smps cpc (2452) back to boulder after it dries out 2019-09-27T22:44:12Z EJA N61 is back to being 2047. now detaching 2438 so can put in SMPS system. 2019-09-27T23:26:42Z EJA restarting after removing second cpc from config 2019-09-27T23:47:55Z EJA did some futzing with cables (mostly clap) about 30 min ago to tidy things up. 2019-09-27T23:49:25Z EJA cpc says 360/cc, smps says 382/cc - that's pretty great since not quite same size range (or tubing length). also, looks like smps goes a little nutty when adding buOH - the size distributions look yucky during that time. 2019-09-28T00:41:35Z EJA betsy out for night. everything should be running as normal 2019-09-28T21:38:44Z BRW betsy stopped in this afternoon to check on system, particularly (no pun intended) the SMPS. it looks great. everything else seems to be humming along. betsy out. changing initials in notes back to BRW 2019-10-01T18:03:52Z BRW smps butanol fill. pld 2019-10-07T18:44:49Z BRW smps butanol top off. pld 2019-10-07T19:06:57Z BRW Ae33 shutdown to clear cf card. pld/bdt 2019-10-07T19:28:34Z BRW ae33 cf card cleared except for 2019. rebooted. pld/bdt 2019-10-11T00:22:25Z BRW spancheck co2 840psi pld 2019-10-11T00:32:10Z BRW spancheck 25psi 5lpm. pld 2019-10-14T19:38:33Z BRW cpc butanol did not stop autofilling. way over filled. butanol in rotometers etc. pld 2019-10-14T20:10:06Z BRW cpc: close to 16 oz of butanol probably flowed through system as fill bottle is empty(was not full to being with). sample flow is reading 4.5 still butanol in rotameter. drier flow rotometer seems clear at this time. pld 2019-10-14T20:41:56Z BRW cpc. sample flow now at 3. reading is 87 and smps 76. pld 2019-10-15T18:47:40Z BRW shutting cpc down to remove to drain butanol. pld 2019-10-15T19:20:04Z BRW cpc back online. running without butanol to allow to dry out. pld 2019-10-21T20:44:20Z BRW smps butanol fill. pld 2019-10-21T20:49:08Z BRW attempting to fill cpc with butanol. zero test cpc and ok. but does not seem to be pumping properly at this time. some butanol did make it in as counts have gone from .75 to 507 close to matching smps computer count. and window does not look dry anymore. pld 2019-10-21T21:00:17Z BRW cpc butanol filled but through drain port manually. would not go through fill port 2019-10-22T21:13:34Z BRW ae33 not reporting to computer. power cycling ae33. pld 2019-10-22T21:37:59Z BRW acquistion system restarted. ae33 is communicating. pld 2019-10-24T19:41:26Z BRW Filter config change did not take upon carousel change end as expected.
