Verifying Settings for the USB-ISS-UV Lamp Module
Q.
The visible lamp for my CHEMUSB4-UV-VIS isn’t working. What should I do?
A.
First, you’ll want to determine the source of the trouble by verifying the software settings in SpectraSuite are correct. To do this, follow these steps:
Disconnect the spectrometer from the USB port of your computer
Connect the power supply to the USB-ISS-UV lamp module
Connect the spectrometer USB cable to the computer
Open SpectraSuite software
Check the Strobe/Lamp Enable selection
If the UV or Visible lamp signal is nor displayed on the graph, right-click on the Spectrometer lamp image on the left column
Select Spectrometer Features
When the Features box is opened, select the UV/VIS tab
Verify that check boxes are selected for both lamps
You can also modify the UV and Visible lamp intensity in this window
If these steps fail to initiate the lamp signals, your spectrometer may require a firmware update. Follow the instructions here to reinstall firmware:
1. Download and install the USB EEPROM Programmer utility from our website:
2. http://www.oceanoptics.com/technical/softwaredownloads.asp
This utility installs the latest version of the microcode for all Ocean Optics devices
3. Connect the USB device to the PC
4. Run the USB programmer by selecting Start | Programs | Ocean Optics | USB Programmer | USB Programmer.
5. In the left pane of the interface, the USB Programmer displays all Ocean Optics USB devices that are currently connected.
6. Click on a device to select it. Once you select a device, detailed information for that device is displayed in the right pane of the interface. The current firmware version of the selected device is displayed in the first entry on the right pane.
7. Press the Program button and select the appropriate EEPROM update file (.IIC file) for your Ocean Optics USB device. Programming begins immediately, and the estimated time for completion of the reprogramming process displays in the bottom status bar.
IMPORTANT: Do not interrupt the programming process for any reason! If the programming process is interrupted, permanent corruption can occur in the EEPROM on the USB device. Consult the Recovering a Corrupted EEPROM section of this document for a procedure that may rectify this condition.
