Battery Replacement
Remove the two screws and carefully lift off the top to expose the attached wires. Remove all four
connectors from the front panel. Place the front panel aside.
Turn the unit over. Remove the four screws holding the battery bracket in place. Remove the two connectors
from each end of the battery. Place the new battery back in the control unit with the terminal furthest away
from the bottom of the enclosure. Fasten the battery bracket into place using the four screws. Re-attach the
four front panel connectors. Replace the front panel the right and left screws.
Cleaning Lenses
To assure regular easy access to the lenses, we have provided two snap closures. The lenses can be wipes
with a soft cloth.
We strongly recommend that a regular procedure of calibration and cleaning the lenses is established.
During light use, a daily cleaning may be enough. During heavy testing, we recommend a frequent cleaning
throughout the day.
To remove soot, dip soft cloth in denatured rubbing alcohol (make sure to let it dry) and rub gently over
lenses.
In laboratory settings and heavy commercial use, please note that we have provided connectors for an
external air purge.
Connecting Cables
Connecting cables are subject to wear, based on incorrect handling, abuse, and contact with a hot stack.
Check, repair, and replace cables when their condition affects the operation of the smoke meter.
Printer
