Maintenance
The high performance Microscanner™ D-Series products are rugged and
durable instruments. They are designed to be used as a tool with long
temperature measurement reliability.
• Calibration
Calibration is performed by a computer through an optical link with the
unit’s micro processor. Because there are no mechanical adjustments,
the instrument is able to maintain its calibration through normal use.
• Cleaning
The only maintenance required is to keep the sensor window clean. This
window, located at the base of the nosepiece’s reflective cup, is made of
a special crystal which passes infrared heat. Dirt, greasy films or moisture
on the win dow will interfere with the passage of infrared heat and affect
the accuracy of the instrument. If necessary, clean the sensor window
and reflective cup with a cotton swab dipped in alcohol or water. Periodic
cleaning is a good practice. When not in use, store in a clean environment.
• Battery
The battery is accessed by removing the instrument’s cover. Loosen the
four screws on the body of the instrument to remove the cover.
