Loading the Sample Cell
A Teflon® spatula (1) is provided with the system. Use this spatula ONLY, because any other type of spatula may scratch the sample cell. Rinse the sample cell with hexane, then dry it with a tissue.Shake the test oil sample or the reference oil sample thoroughly before loading into the sample cell. Run the test immediately.Use the spatula or a disposable eye dropper to spread enough of the test oil sample or the reference oil sample from the vial, to cover the sample cell. Do not scrape the sample cell because there may be abrasive materials in the fluid that will damage the sample cell.Calibration Instructions
From the main menu, press OTHER FUNCTIONS.From the next menu, press CALIBRATE. The system will display: Clean cell then press RUNUsing the cleaning instructions given previously, clean the sample cell, then press RUN.If the sample cell was not clean enough, the system will ask you to clean it again. Following this, press any key to continue.The system will now begin to scan the background. When scanning is completed, the system will display: Load calibration liquid press RUN when readyPour 99% PURE CYCLOHEXANE (do not use hexane) into the sample cell trough to cover the sample cell.
