Quick checks for the issues we hear about most often. If nothing here matches what you're seeing, contact support.
Studio doesn't see the instrument
If the device panel in Studio reads as disconnected, work through the following in order.
- Check the USB cable. USB-C charging cables don't always carry data. Use the cable that came with the instrument or a known-good data cable.
- Try a different USB port. Avoid hubs for the first connection; plug straight into the laptop.
- Check the LED. See the table below. A green LED means the instrument is connected and ready.
- Restart Studio. Quit completely and reopen. Studio re-enumerates the USB device on launch.
- If none of those work, contact support.
Status LED reference
The front-panel LED tells you where in the connection process the instrument is.
| LED | Meaning |
|---|---|
| Red | Powered. The instrument is connected to power but not yet to a host over USB. |
| Green | Ready. USB is connected and the instrument is talking to Studio. |
| Orange | Running. An experiment is in progress. |
| Green blink | USB communication is up but PPS power is not connected. ECA-LP1 needs the PPS adapter to operate at full compliance. Connect it before running an experiment. |
Studio crashes, freezes, or fails to save
- Studio stops responding. Quit and reopen. Recent experiments are autosaved to the folder shown at the top of the Method Setup panel, so they survive a restart.
- An export fails. Check that the destination folder exists and that you have write access. Try saving to your home folder first to rule out permissions.
- The autosave folder fills up. Point Method Setup at a different drive via Change, or move the existing files out and let Studio re-create the folder.
Noisy or wandering trace
If the trace looks unusually noisy and the cell setup itself is sound:
- Reseat the electrode cable. A loose Lemo or banana contact is the most common source. Unplug, inspect, and push it back in firmly.
- Turn on the filter. In voltammetry parameter panels, the Enable filter checkbox applies a Savitzky-Golay smoothing pass. See filter a signal. Leave it on for routine work.
- Move the power adapter to a different outlet. Ground loops between the laptop power supply, the instrument, and nearby benchtop equipment can show up as a slow oscillation on the trace. A different outlet or a battery-powered laptop usually settles it.
Sharing logs with support
Studio doesn't yet write logs to a standard location. If you need to send debugging information, contact support and we'll walk you through grabbing what we need.
