When a Go Direct® SpectroVis® Plus Spectrophotometer (GDX-SVISPL) is connected via USB, if the indicator lights on the front of the unit are not as expected and the spectrometer does not ID in Spectral Analysis, Logger Pro, or LabQuest App, there is likely a power issue with the spectrometer. Try the following to get the unit to connect.
- Make sure you are using the appropriate version of software:
- Original LabQuest version 1.7.6. Free updates are available here:

- LabQuest software version 2.7.2 or newer. Free updates are available here: https://www.vernier.com/downloads/labquest-2-updates/
- Logger Pro software version 3.15 or newer. Free updates are available here:

- Unplug and replug the USB cable. NOTE: If you are collecting data via USB, you do NOT need the battery installed or the AC power cable connected. Removing both of these will likely solve most issues.
- Switch the USB cable with one that you know works.
- Switch to a shorter USB cable.
- Do not use any adapters on the USB cables.
- Use a powered USB hub between the spectrometer and the computer or LabQuest, if possible.
- If you are on a LabQuest unit, completely reboot the LabQuest
- Original LabQuest⚊Home > Control Panel > Reboot
- LabQuest 2⚊Home > System > Reboot
- LabQuest 3⚊Choose Reboot from the Settings screen
- Unplug the spectrometer from all cables. Press and hold the power button until the LEDs go off and try reconnecting.
- Attach the AC power cable that came with the unit and then plug the USB cable into your platform. Charge the spectrometer for an hour with the AC power cable and try connecting again.
- Remove the battery. You will never need the battery or the AC power cable if you are only collecting data via USB.
For Bluetooth specific issues, see Why can't my device find Go Direct Spectrometer when I try to connect via Bluetooth?
If none of these fix the issue or you have to do this repeatedly with the same spectrometer, Please contact Vernier Technical Support. Please include the serial number of the unit.
