This guide details the operations needed to obtain engineering outputs from a Soil Instruments Data Acquisition System (DAS) that has the “Datalogger output engineering units” addon (D5-1.7). This is done by loading calibration and/or conversion factors applicable to the individual sensors using comma separated files (CSV) to the DAS. These factors will be found on the calibration sheets that come with each sensor. This guide presumes the user is competent with the operation of Loggernet. For more information on Loggernet please see the knowledgebase article “Datalogger Quick Guide” available from www.soilsupport.co.uk.

  2.             Downloading CSV Files

The templates that will require to be modified and are applicable to the DAS’s specific sensor setup will be found within the USR memory drive of the system. These can be accessed by doing the following steps:

Connect with the logger and access “File Control”

Select “USR” under device on the “File Control” window

Highlight the CSV files and select “Retrieve”

Save the files for editing/checking

 3.            Configuring CSV Files

NOTE: If relevant sensor information was available during the production of the DAS, the calibration factors will already have been setup for the logger. These will be allowing for the sensors to be wired into the logger or multiplexer channels in numerical order (smallest to largest) by their serial numbers. Please follow step  

3.1  Identifying the CSV File Type

NOTE: DO NOT change the file names or extension of the CSV files that were originally downloaded from the loggers USR drive, otherwise they will not be recognized by the DAS software when re-uploaded. 

The file name will indicate what type of instrument it is for and which factor is needed to be inputted to it.

For example: 

IPI_b0.csv

Will need the “b0” calibration factors (can be either mm/m or ArcDegrees) for all the IPI (In-Place-Inclinometers) attached to the logger/multiplexers for the DAS.

For example:

EL_Base.csv

Will need the raw “Base” readings for all of the “EL” (Electrolevels) attached to the logger/multiplexers for the DAS.

3.2  Modifying the CSV Files

NOTE: The recommended software for editing the files is Microsoft Excel. Alternative software can be used for example Textpad, though others may not present the file in an as easily manageable format.

Open the relevant CSV file in excel.

The multiplexer or logger channel will be in the top row of the file the corresponding value will be in the column below.

For example:

(IPI_b1.csv)

Top row indicating multiplexer number channel number

Second row corresponding value

NOTE: See DAS accompanying wiring diagram for sensor channel wiring.

Save the file ensuring that it is still in CSV format.

These files can then be reuploaded to the USR drive from where they were downloaded.

 4.            Uploading CSV Files

Connect with the logger and access “File Control”

Select “USR” under device on the “File Control” window

Highlight the CSV files and select “Send”

In the pop up window change the file type to “All Files”.

Select the files for sending.

Select “Open”.

The files will now appear in the Datalogger’s USR drive.

The logger will need to have the power cycled for the program to start using the uploaded files.
