Cleaning the Calibration Reference1. Position the reading head to the center of the measurement path using ToolCrib (see related support articles on the left).
2. Disconnect the power supply from the instrument.
3. Remove the front cover by pulling forward on the lower portion. After the lower portion
of the cover is free, rotate it upwards to free the upper portion from the rear cover. Set
the cover aside.
4. Clean the calibration reference using a cotton swab or lint free cloth. Wipe from
left-to-right to minimize lint collection. If needed, a small quantity of water or alcohol can be used to clean the calibration reference.
Do not use any other solvents or glass cleaner.
5. Reinstall the front cover by inserting the top portion into the rear cover and rotating
downward. Push the lower portion of the front cover inward until it is flush with the
bottom housing.
