Lt Sampling connects compatible PowerLab Sensors to Lt so you can record live data directly into your lessons. Install the app on the Mac or Windows computer connected to your sensors, then record and analyse the results in Lt.
Download Lt Sampling
Choose the installer for the computer you will use to collect data.
Data sampling is not currently supported on ChromeOS, Android, iPadOS, or iOS. Use a compatible Mac or Windows computer to record live data in Lt.
Using Lt LabStation?
These downloads are for recording data in Lt. Lt LabStation is a standalone Windows application with its own data service. It does not require a separate installation of Lt Sampling or the kuraCloud Desktop Application (KCDA).
Get started
- Install and open Lt Sampling. Install the app on the computer connected to your sensors. On a managed computer, ask your IT team to help with installation if needed.
- Enable Lt Sampling for the course. A course administrator opens Course settings > Lt Sampling and turns on Lt Sampling.
- Connect your sensors. Connect the compatible sensors required by the lesson to an available USB port or suitable USB hub.
- Open the lesson in Lt. Go to the page containing the configured Data Sampling or Scope Sampling panel.
- Start recording. Follow the lesson instructions and select Start. Keep Lt Sampling running while you collect data.
If Lt prompts you to install, open, or update Lt Sampling, follow the on-screen instructions before recording.
What you can do
- Record live signals: collect sensor data directly into your Lt lesson.
- See results as you record: view signals in the lesson's sampling panel.
- Analyse data in Lt: use the lesson's tools and activities to explore the recorded results.
Compatible sensors
Lt Sampling supports compatible PowerLab Sensors, including earlier Lt Sensors. Examples include:
- Biopotential Sensor
- Blood Pressure Sensor
- Cardio Microphone Sensor
- Finger Pulse Sensor
- Grip Force Sensor
- Respiratory Belt Sensor
- Skin Temperature Sensor
- Spirometer Sensor
- Tendon Hammer Sensor
Check the hardware compatibility guide for supported devices and accessories. Your lesson must be configured for the sensors you are using.

Use a browser supported by Lt on your operating system. See the Lt system requirements for browser compatibility.
Windows installation notes
PowerLab driver
PowerLab Sensors may require the ADInstruments PowerLab driver on Windows. If Lt reports that the driver is missing, follow the Windows installation guide (PDF) or ask your IT team to install it. Installing Lt Sampling from the Microsoft Store does not necessarily install this driver.
Using Lt Sampling alongside kuraCloud Desktop
Lt Sampling and the kuraCloud Desktop Application (KCDA) can be installed on the same Windows computer. When both are installed, Lt Sampling handles compatible sensors, while KCDA handles compatible PowerLab data acquisition units.
If you use both applications, use KCDA version 1.13.4 or later and keep Lt Sampling up to date. Restart the applications after updating if Lt does not detect your sensors.
If your sensors are not detected
- Check that Lt Sampling is installed and running, and that it is enabled for your course.
- Check the sensor connection and reconnect the device if needed.
- Close other applications that may be using the same device.
- On Windows, check for a missing PowerLab driver message.
- If your browser asks you to allow Lt to connect to local devices or apps on your computer, follow the browser connection troubleshooting guide.
If the problem continues, contact ADInstruments Technical Support. Include your operating system, browser, sensor model, and any error message. Support may ask you to use Save Diagnostics... from the Lt Sampling menu.
