Section 15- Troubleshooting
Connection Error
This error occurs whenever the USB connection is disrupted while operating a software module. In most cases, selecting 'Retry' will
reconnect properly. Some possible causes and solutions are listed below:
Power management scheme on the PC:
If your PC is automatically going into standby or hibernate mode, the USB communication will be lost whenever it occurs and 'Retry' will
NOT reconnect the instrument. If this occurs, the USB cable will need to be disconnected/reconnected before selecting 'Retry'.
You can confirm that the power management settings are correct by opening the Power Options Properties page by choosing Start
Control Panel
Power Options. The 'System Standby' and 'System Hibernate' should be set to 'never' for the 'Plugged In' column as
shown below.
Static Electricity Discharge
Discharge from the user to the instrument can be a problem in very dry environments. It may be necessary for the user to wear a
grounding strap to prevent the discharges from occurring.
Defective USB Port on PC
If your instrument operates properly most of the time, but the Connection Error appears intermittently, it could be caused by the USB
port on the PC. If this occurs, install the software and operate on another PC. If the error does not occur on the second PC, it may be
necessary to replace the USB card on the original PC.
Signal Error
This error occurs because no light or not enough light is reaching the detector. If the troubleshooting steps outlined in the message do
not fix the problem, perform an Intensity Check:
•
Open the Utilities and Diagnostics module from the main menu.
