Sensor Mirror Cleaning

Throughout the life of the instrument, periodic cleaning of the mirror surface and optics
window may be required. Sensor cleaning is mandatory if the instrument indicates an
optics fault.
The cleaning procedure is as follows:
1. Switch off the instrument and remove the sensor from its sample block.
2. Clean the mirror surface and optics window with a cotton bud/Q-Tip
soaked in distilled water. If the sensor has been exposed to oil based
contamination then use one of the following solvents: methanol, ethanol,
or isopropyl alcohol. To avoid damage to the mirror surface do not press
too fi rmly on the cotton bud/Q-Tip when cleaning. Allow the cleaning
solvent to fully evaporate.
3. Reset the mirror condition according to the instructions in Section 5.2.
