NOTICE
We recommend that you keep the spectrometer sealed and desiccated, or sealed and purged with dry
air or nitrogen, at all times. Equipment damage due to failure to maintain seal and desiccation and/or
purge is not covered under the warranty. If you have questions about this requirement, please contact
us.
CHECK THE PURGE GAS FILTER
If your Summit spectrometer is purged with nitrogen or dry air, check the purge filter at least once a
month.
Replace the filter when it is yellow, or otherwise discolored, or if it is contaminated with debris or foreign
particles. For more information, see
"Check and Change the Purge Gas Filter"
