Loggernet interface

Connect to the Droughtbox

• Open LoggerNet v4.1

• Initial connect: Go to Main --> and click on Connect

  

• Connect to the Droughtbox: Select the Droughtbox and press Connect

  

Create a data file

• Create data file: Go back to the main interface and press the setup bottom

• Create a new file: Select Droughtbox at COM32 --> Go to the Data Files tab --> Select droughtbox --> change the name of the file following the format YYYY_MM_DATE_OWNER.dat for example 2023_08_10_erick.dat

• Make sure that the File Output Option is set up as Create unique file name

• To save the data into the file press the Collect Now bottom. This step must be done each time you want to save data

• If you don't change the file path, your data file will be stored at C:\Campbellsci\LoggerNet

• In case that Network Map (located at the left hand of the image below) is not as shown in the picture, click on the View bottom and select Standard to change it.

  

Open the numeric display

• Open Num Display: Press Num Display bottom

• This window should appear

• The main inputs that can be change are:
  • SetPointT
  • SetPointVPD
  • SetPointAbsH
  • SetPointRH

List of abbreviations in the numerical display

Term	Definition	Units
BattV	Voltage Battery Reading
PTempC	Logger panel temperature (room temp)
AirTC	Air temp in box measured by Temp/RH sensor (slow response)
RH	Measured relative humidity inside the box
TC	Air temp in box measured by fine wired thermocouple (fast response)
VPD	Measured vapor pressure deficit inside the box, calculated from RH and AirTc
AbsH	Measured absolute humidity inside the box, calculated from RH and AirTc
Strain(1)	Weight measured on strain 1	grams
Strain(2)	Weight measured on strain 2	grams
Strain(3)	Weight measured on strain 3	grams
Strain(4)	Weight measured on strain 4	grams
TarePeriod	Time between automatic zeros (load is lifted from strain gauges and output signal taken as zero mass)
err	Used during tare to make sure values are stable
TareCount	Each time a tare occurs, TareCount is incremented by 1. The current value is stored in each data record. Makes it easy in R to use the values close to a tare event.
TareNow	Is a Boolean (`true` or `false`) flag either set by the code at each tare period or manually set `true` to force a tare.
autozero	if `true` the tare function is active, if `false` it is not.
SetPointRH	Desired Relative Humidity, calculated from SetPointVPD and SetPointT.
SetPointT	Desired Temperature
SetPointVPD	Desired vapor pressure deficit
SetPointAbsH	Desired absolute humidity, calculated from SetpointVPD and SetPointT	grams
