# Do measurements in Access

Did you know that you can connect BactoBox® to a computer and do the measuremnets via **Access** . Access allows you to store essential information such as sample description, sampling time, and dilution factor alongside your measurements.

The video below shows a growth curve experiment monitored and recorded in Access.

In this mini course we will show you the essentials of how to run measurements in Access.

{% step %}

### Open Access

Connect your BactoBox® to your computer and open Access in your browser. The familiar BactoBox® buttons move onto your screen.

{% endstep %}

{% step %}

### Create a measurement group

Start a *basic* measurement group as shown in the video. Basic is the simplest measurements view. It merely groups the measurements together. Doesn't offer additional analytics or plotting.

{% endstep %}

{% step %}

### Measure and annotate each sample

Set the sampling time, dilution factor and a label. Then click <kbd><mark style="background-color:purple;">Measure<mark style="background-color:purple;"></kbd> to run the measurement.

When the measurement is completed, Access automatically works out the concentration in the non-diluted culture and adds it to the table.

{% endstep %}
{% endstepper %}

## Learn the ropes

This mini course showed you how to do a basic BactoBox® measurement via Access.

There are is a more advanced feature in Access that allows you to visualize a growth curve in real time. Click the link below to learn more.

## Next steps

With these 3 measurement essentials mini courses, you now have a foundation for testing your own cultures. In principle you can now proceed to our [Workflows](/mpd/workflows/bioprocess-workflows.md) in [Microbial process development](https://help.sbtinstruments.com/mpd/)

Before doing so, we highly recommend that you complete tutorials 1-3 or at least consider these as a fall-back option if you run into technical difficulties with your own cultures.

In any case, we are always happy to help. If you find yourself stuck, feel free to [Contact our support team](/troubleshooting/contact-our-support-team/contact-our-support-team.md) for assistance.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.sbtinstruments.com/measurement-essentials/do-measurements-in-access.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
