5.
Rinse the baffle assembly with clean water. Wipe it off
with a clean dry cloth if necessary.
6.
Insert the baffle assembly into the flow chamber and
replace the cover (for high pressure design sensor, re-
place O-ring, window, and lockring).
NOTE:
Make sure the cover O-ring is well lubricated
with the supplied lubricant, and properly seated
before tightening the cover or lockring. If not,
the cover may be difficult to remove next time.
Recommendation:
When not in use, properly store the Cal-
Cube
TM
assembly inside its protective box in a cool, dry place.
If dirt or dust accumulates on the glass cube,
do not touch
its surface with your fingers
. Finger oil will change its
certified value. Dip the cube assembly in isopropyl alcohol
to remove dust and finger oil. Use compressed air or a soft,
clean optical cloth to dry the cube.
CAUTION:
DO NOT WIPE THE GLASS CUBE WITH TISSUES OR
PAPER TOWELS. SMALL WOOD FIBERS FOUND IN
THESE PRODUCTS WILL SCRATCH THE GLASS
SURFACE OF THE CUBE WHICH MAY CHANGE ITS
CERTIFIED VALUE.
