MAINTENANCE AND CLEANING
The
KHACHIK CHECK
needs no regular maintenance and has no
user-maintanable parts.
To ensure consistent measurement quality, a regular cleaning is
recommended. Please use a slightly damp, soft cleaning cloth.
Never use paint thinner, benzene, alcohol, disinfectants or sanitizers, or
other strong cleaning agents when cleaning the
KHACHIK CHECK
, as these
could damage the case and the optical surface of the sensor.
If needed, the sensor surface can be disinfected by wiping it with a cloth
with 70% isopropanol.
