Troubleshooting

Overview

The following sections contain information on troubleshooting issues you may encounter when using the
QE65000 Spectrometer.

QE65000 Connected to PC Prior to OOIBase32
Installation

If you connected your Ocean Optics USB device to the computer prior to installing your Ocean Optics
software application, you may encounter installation issues that you must correct before your Ocean
Optics device will operate properly.

Follow the applicable steps below to remove the incorrectly installed device, device driver, and
installation files.

Note

If these procedures do not correct your device driver problem, you must obtain the
