Revision as of 11:39, 3 June 2016
- bring measuring cup set for leveling UVA and UVB sensors
- wire junction to split all instruments needing 12V from logger
- swap out quantum sensors
- bring mini wrench to replace them
figure out what the connection is like at toolikchange calibration constant?
- remove old radio
- get field books from Brie
- swap CNR4, change constants in program
- install new barometer
- change program calibration constants
- we zero out the CMP6, but not the CNR4. reconsider?
Contents
install new evap pan
- leak test (marine epoxy in case of leaks. should be up in the EDC office)
- clean out bottom
- field calibrate
Fill pan partway with water, measure height with ruler in mm Measure voltage by reading the EvapLevelTemp variable on the program Add more water, measure water depth in pan Measure voltage Calculate multiplier and offset using y = mx+b m(multiplier) = (height1-height2)/(voltage2-voltage1) b(offset) = height1-(m*voltage1)
Change multiplier and offset in program
calibrate precip
Tipping bucket
- fill bottle to line, use smallest orifice, do this 3 times
- should be 30mm per bottle, so 90mm total
- change multiplier in program if necessary
Pluvio accuracy test
- received software in ftp from ott (on my fancy laptop, need to transfer to toughbook)
- need usb cable
Brie Helps with
- swap in fancier wind sensor 5108-45-12M
- swap out HMP155s
- write down which height is which SN
- download garden cam images
- bring replacement batteries
- to turn off: press and hold organge power button until 3 beeps and green LED turns off
- remove drive, download and clear images on computer
- to turn on:press and hold organge power button until green LED lights up. after a few sec beep twice. green LED every 15 sec indicates normal running. if any other beeping or lights, consult manual
take photos of sensors without pics on instrumentation site
- HMP155
- wind sensors
- snow dept
- barometer
- evap pan
program changes
- evap pan calibration
- possible tipping bucket calibration
- possible pluvio calibration
- UVA+UVB corrections. UVA:0.0221, UVB: 0.00178 (per Lija's email)
- CNR4 constants
- LW up: 7.51
- LW down: 8.24
- SW up: 16.77
- SW down: 14.82
get SN of all instruments/loggers on google sheet
- datalogger,mux, radios, nl__
- both wind sensors,cmp4, cmp6, evap gauge, precips
- basically everything
To change on instrumentation website
- pluvio is actually version 2
- lake temp measurement
- barometer
to bring
- laptop + charger
- field laptop + charger
- tipping bucket calibration box
- gloves, hat(warm and sun)
- tools
- wire junction
- hiking boots,rubber boots,running shoes
- field book
- usb cable for pluvio
- batteries for garden cam
- cookies for brie
- instruments
- anemometer
- CNR4
- Two HMP155s
- baromter
- quantum
