MA68II - Cleaning

Your instrument requires very little maintenance to achieve years of reliable operation. However, to protect your investment and maintain reading accuracy, a few simple-cleaning procedures should be performed from time to time.

General Cleaning

The exterior of the instrument may be wiped clean with a cloth dampened in water or mild cleaner.

NOTE: DO NOT use any solvents to the clean the instrument, this will cause damage to the cover.
 

Cleaning the Optics

The optics should be cleaned once a week in a normal environment. If the instrument is used in a dirty or dusty environment, more frequent cleaning may be required.
Carefully lift the instrument and blow short bursts of clean, dry air into the measurement port. This should remove any accumulated debris from the optics.

IMPORTANT: If can air is used for cleaning, do not invert or tilt the can during use. This could cause damage to the optics.
 

Cleaning the Calibration Reference

The white plaque in the calibration reference should be cleaned using a mild soap and warm water solution, thoroughly rinsed with warm water, and wiped dry with a clean, lint-free cloth. You must let the plaque dry completely before taking a calibration measurement.
 

Cleaning the Black Trap

The black trap should be cleaned with clean, dry air from time to time to remove any dust or contamination. The black trap can be taken apart for easy cleaning. Simply compress the two locking tabs on both sides of the case with your fingers, and separating the two sections.
