Digit Quickstart Tutorial (Discontinued)

Digit Quickstart for Windows

1.  Download and install the LabJack software and driver bundle. The Digit software is called Otero (Windows only), and is part of the Windows Installer. There is no utility application for Linux and Mac at this time.

2. Plug Digit-TL/H into USB port.

3.  Open Otero from the start menu, or manually in C:\Program Files (x86)\LabJack\Applications\Otero.exe

4. Select which items will be logged.

5. Select a log interval (how frequently data is collected).

6. Change to Data tab, see real-time data.

7. Download the data from prior log session.  A file dialog will appear to save the data to a file.

8. To start a new logging session, click "Erase Data & Begin New Logging Session".  It takes 3-5 seconds to erase.

9. Exit the program, the Digit is ready to continue logging.


For detailed specifications, see the datasheet.  For more information about the software, see the Otero page.  If you would like to update your firmware, proceed to the firmware page.

Otero (Digit Software) Users Manual

Note: Foreign objects inside the enclosure present a risk of damaging the board when the base is twisted off because they can catch and bind. Customers who purchased the aluminum enclosure add-on should remove the spare O-rings before use.  Here is a video demonstration of how to put a Digit-TL into its enclosure.

File Attachment: 


Is the Digit capable of accurately measuring RH while in the waterproof container?

It needs to have the vented enclosure in order to measure ambient humidity. In a fully sealed enclosure, ambient air is not mixing with the air inside the enclosure, so humidity readings are not valid if it's inside of a watertight/airtight case.  If it is locked inside of an airtight chamber, the humidity inside the chamber may change (mostly due to temperature changes), but the reading isn't all that helpful.

Are there plans to have a simple download program to recover data?

The Otero software is very badly designed and leads to loss of data.


No plans for a different download program at this time.  To keep the cost of the Digit low a lot of complexity is handled by software, so it is not trivial to pull data off the device.  The best option at this time seems to discuss tweaks to Otero that would make a difference for you.  I would continue that on the forum.

We have not heard of or seen any data loss issues, but are supporting this issue in your forum topic 7056.

Hi, i am looking for a simple method to dump data from the Digit-tl to Mac OS X in the .csv format.  I am not a programmer, so i am looking for a simple program.  Thanks!

At this time there is no way to download data to Mac OS X.  We do have plans to incorporate Digit-TL/TLH support into our cross-platform application(Kipling), but the timeline on that project is uncertain.  If you plan to purchase Digit-TL devices in volume, please email us, we might be able to accelerate Mac OS X support if demand is large enough.

I want Mac support too. Accelerate!

It appears that there is no print function to print the Data tab as shown on page 4 of the manual. Would I be able to print this graph by mouse right-click for a print option?

One method of printing the graph captured and displayed by Otero is to do a screen capture.  Another is to open the downloaded .csv file in OpenOffice, Excel, or Google Docs, graph the data, and then print using their print function.  Do either of these options work for you?

Yes, thank you. Will be placing an order.
