# Reading data from the logger memory

To retrieve data from a selected logger’s memory, tap the logger in the list. When connecting for the first time, the application will ask for the logger’s PIN code. The PIN code is printed on the label on the side of the device.

After connecting to the logger and downloading the stored measurements, the application displays a summary screen. This summary includes:

* Minimum and maximum values for each monitored parameter, along with their timestamps
* A chart showing measurement trends over time
* The current measurement interval, available memory, and an estimate of how long the memory will last
* Date and time of the first and last stored measurements
* Logger software version

## Charts

Tap the chart in the summary view to open a detailed version.\
You can:

* Zoom in and out using pinch gestures
* Scroll through the chart to view data over time

Red and blue lines show the minimum and maximum values in the measurement series.\
If the logger monitors more than one parameter, you can choose which one to display using the dropdown menu at the top of the chart.

## Exporting the data

To export data, tap the **export icon** (first icon on the left in the top menu).

Then:

{% stepper %}
{% step %}

#### Select the export format

* **CSV** – contains raw data; compatible with Excel, MATLAB, and most data-processing tools
* **PDF** – contains a non-editable report including a chart; suitable for documentation
  {% endstep %}

{% step %}

#### Select the type of data to export

* **Raw data** – Individual measurement values recorded by the logger.
* **Daily statistics** – Daily averages, minimums, and maximums stored in the logger’s memory.
* **Monthly statistics** – Monthly averages, minimums, and maximums stored in the logger’s memory.
* **Vineyard statistics (SAAT and GDDC)** – Indicators used in grape cultivation. Available only for loggers that measure temperature.
* **Mean kinetic temperature** – Calculated MKT values. Available only for loggers that measure temperature.
  {% endstep %}

{% step %}

#### Select the time range

Select the start and end date (including time) for the data you want to export.
{% endstep %}

{% step %}

#### Export the data

Press the Export button and select how do you want to share the exported files. You can use any application installed on your device (e-mail, Google Drive, Dropbox, FTP, Bluetooth/Wi-Fi printers, etc.).
{% endstep %}
{% endstepper %}

## Statistics

The application can calculate statistical parameters based on the downloaded data. To view statistics, tap the **statistics icon** (first icon on the right in the top menu).&#x20;

<figure><img src="/files/7VVT1VhqBQh9cyfpSpFA" alt=""><figcaption></figcaption></figure>

Available statistics include:

* **Average values** – daily or monthly averages
* **Minimum and maximum values** – daily or monthly extremes
* **SAT and GDDC** – parameters used in viticulture. Available only for loggers that measure temperature.
* **Mean Kinetic Temperature** – evaluates the impact of temperature fluctuations on drug quality and is useful when assessing temporary excursions outside recommended storage temperatures. Available only for loggers that measure temperature.
* **Length of the Growing Season (LGS)** – number of days with average daily temperature above 10 °C; values above 182 indicate conditions suitable for viticulture. Available only for loggers that measure temperature.
* **Huglin Index (HI)** – sum of active temperatures from April to September (northern hemisphere); includes day length, average temperature, and maximum temperature. Used to classify climate suitability for grape cultivation.

  If the user allows, the application uses GPS to determine location and calculate the Huglin Index accurately for the specific measurement site. Available only for loggers that measure temperature.
* **Cool Nights Index (CNI)** – average minimum temperature during the month before harvest (September in the northern hemisphere, March in the southern hemisphere).\
  If the user allows, the application uses GPS to determine location and calculate the Cool Nigths Index accurately for the specific measurement site. Available only for loggers that measure temperature.
