Start, Configure, and Clear Tinytag

See also our instructional videos.

If you cannot connect to your Tinytag and have not already done so, you need to install drivers. If you have installed the drivers and still cannot connect, the most common issue is that the battery needs to be replaced.

Remember to clear your logger and save the file before starting a new measurement. The new measurement will overwrite the old measurement data.

Go to the homepage and click on Gemini Tinytag.

A new page will open that looks like this:

The page lists the computer's COM ports and any connected Tinytags. You will see a summary for each Tinytag showing the status and the current configuration.

• Multimeter displays the logger's measurement values on the screen, but nothing is saved.
• Retrieve Data reads the logger's data and creates a measurement file.
• Configure/Start begins the configuration of the logger.
• Start initiates a new measurement with the same configuration as last time.

Configuration opens a new dialog:

Here you can change whether the logger should start with a delay (e.g., tomorrow at 08:00).

You can set what happens when the memory is full, any alarm levels, and how often the logger should save a measurement value.

Rolling memory means that the logger will overwrite the oldest value when the memory is full.

If you sample less frequently than once a minute, you can check Max and Min. For example, if you set the interval to 10 minutes and check Max and Min, the logger will wake up and check the value every minute. After 10 minutes, it will also save the highest and lowest values in the measurement file.

If you are measuring with a Tinytag that has both temperature and humidity, you can check the box for Calculate Dew Point. This will create a third channel in the measurement file that shows the dew point temperature.

Limiting RH between 0 and 100% can be useful for condensation prevention.

Go to the homepage and click on Gemini Tinytag.

A new page will open that looks like this:

The page lists the computer's COM ports and any connected Tinytags. You will see a summary for each Tinytag showing the status and the current configuration.

Further down the page, there is a button that looks like this—click on it:

This will open a new dialog box:

At the top, you choose what you want to do. If you want to start a new measurement, it should say "Stop > Start."

Start Conditions: Here you select how you want to start your loggers.

• Start Immediately – starts here and now
• Magnet Start – loggers wait to be started with a magnet (rarely used)
• At Specified Time
• Delayed Start – specify how far in the future you want to start the units
• Delayed Magnet Start (rarely used)

Title: Here you specify what the units should be named. All Tinytags have a unique serial number under the barcode on the casing. If you want this, enter {SERIAL}. To get the {-character, you usually use Alt Gr + 7.
Otherwise, there are a few other macros available as options below.

• NR = Run number, e.g., "Logger {NR}" becomes: Logger 1, Logger 2, Logger 3
• {DATE} = Use the start date in the title
• {TIME} = Use the start time

If you want to keep the existing names of the titles, check the box on the right instead.

Interval: Here you write the measurement interval you want to use. For example, for indoor climate, we usually set it to 10 minutes.

Storage: Most people only use normal values (Normal) here, which is recommended. If you check the others (Min and Max), each channel will have three curves instead of one.

When you are done with the above, click the "Activate" button. A dialog box will pop up. Check "Yes" if you have saved all previous measurements.

Then just disconnect the first logger when it is checked as "started" according to the table below and plug in the next one.

Once you have started your loggers, click on "Deactivate," and you can close the dialog box.

Tip!
If you want to check that your loggers are started, there is a button on the homepage in EasyView that looks like this:

If you click there, you can check that your loggers have started correctly. Here you can always see what has been done last with each unit.

Stop Measurement and Retrieve Data from Multiple Units Quickly.

Click on 
Change the menu to "Stop > Retrieve Data" and then click on the "Retrieval Options" tab as shown in the image.

Here you choose how you want your data to be handled/saved.

Then just click "Activate" at the bottom and disconnect the first logger when it is checked as "Stopped" and "Data Retrieved" according to the table below, and plug in the next one.

When you are done, click "Deactivate," and you can close the dialog box. Your measurements will then open/save according to your previous choices.
