To record data in browser-based Lt, you need a compatible computer, supported hardware, the appropriate sampling software, and a lesson configured for that hardware. Viewing lessons and recording live data have different requirements.
Sampling platform limits: Data sampling in Lt is not currently supported on ChromeOS, Android, iPadOS, or iOS.
Choose your hardware and sampling software
| Computer | Hardware | Required software |
|---|---|---|
| Windows | Compatible PowerLab acquisition unit | kuraCloud Desktop Application (KCDA) |
| Windows | Compatible PowerLab Sensors or earlier Lt Sensors | Lt Sampling Application for Windows |
| macOS | Compatible PowerLab Sensors or earlier Lt Sensors | Lt Sampling Application for macOS |
PowerLab acquisition units require KCDA on Windows for use with Lt. Lt Sampling does not replace KCDA for these units, and KCDA is not available for macOS. Check the PowerLab and sensor compatibility guide for your exact model.
Using Lt LabStation? Lt LabStation is a standalone Windows product with its own Data Service. It does not require a separate KCDA or Lt Sampling installation. The browser requirements below apply to browser-based Lt.
Computer requirements
| Requirement | Windows | macOS |
|---|---|---|
| Operating system | Use a Windows release maintained under your institution’s support policy and compatible with your chosen installer and a current Lt-supported browser. Lt Sampling uses 64-bit Windows. | Use a macOS release compatible with the current Lt Sampling installer and an Lt-supported browser. |
| Memory | 4 GB minimum; 8 GB or more recommended | 4 GB minimum; 8 GB or more recommended |
| Processor | Modern Intel or AMD processor with at least two cores | A compatible Intel or Apple silicon Mac; use the appropriate application build |
| Free storage | 5 GB | 5 GB |
| USB connection | A suitable USB port, USB 2.0 or later | A suitable USB port, USB 2.0 or later; an appropriate adapter or hub may be needed for USB-C ports |
| Internet | Broadband internet connection | Broadband internet connection |
Check the installer before deployment. Requirements can differ by application and package format. The Lt Sampling Windows MSIX package requires Windows 10 version 1809 (build 17763) or later. This package minimum does not establish support for every Windows release or browser combination.
Earlier documentation listed Windows 8 and macOS 10.13 as minimum operating systems. These historical minimums should not be used alone to select computers for a new deployment. Confirm compatibility with the current installer and browser before installing across a teaching lab.
Browser requirements
Use the latest version of an Lt-supported browser. Google Chrome is recommended for sampling; the published sampling requirements also list Mozilla Firefox and Microsoft Edge. Keep the operating system and browser compatible with one another.
When Chrome or Edge asks for permission to access applications on your device or your local network, allow the relevant permission for the site displaying your Lt lesson. Blocking this permission can prevent the browser from connecting to installed sampling software.
See Lt Support for browser local-device permission guidance and other sampling troubleshooting resources.
Lab configurations that are not supported
The following configurations are not supported for Lt sampling. These restrictions concern recording with local hardware; they do not mean that all Lt lesson viewing is incompatible with these environments.
| Configuration | What to consider |
|---|---|
| Virtual machines | Hardware access and USB forwarding may not work reliably. Use a supported physical computer for sampling. |
| Thin clients | Local sampling software and connected hardware require a supported workstation setup. |
| Reboot-to-restore or reimaging systems, such as Deep Freeze | Restoring the computer can remove application updates, local settings, or required permissions. Review the setup with IT before deployment. |
| Enforced proxies | Proxy rules can interfere with application connectivity or connections between Lt and the local sampling service. Review network requirements with IT. |
Do not disable institutional security controls to work around a connection problem. Ask IT or ADInstruments Technical Support to review the configuration.
Install and verify before class
- Confirm the exact computer, operating system, hardware model, and lesson configuration.
- Install the appropriate sampling software and any required drivers using your institution’s approved method.
- Connect the hardware, open the intended sampling lesson, and allow any required browser permissions.
- Record a short test using a standard student account on the lab computer. Check the setup again after significant software or computer-image changes.
Use the Lt Sampling Application setup and downloads for sensors, or the KCDA setup and downloads for compatible PowerLab acquisition units.
IT installation guides: Lt Sampling for Windows (PDF), Lt Sampling for macOS (PDF), and KCDA for Windows (PDF).
For help choosing or validating a setup, contact ADInstruments Technical Support. Include your operating system, browser version, sampling application, hardware model, and details of any managed lab configuration.
