Check for Leaks
The Camera may be checked for leaks by setting it aside for a period of several days and
rechecking N
2
levels. As gas pressure depends on temperature, ambient temperature should
be similar when re-checking pressure levels. A reduction of 2 counts of N
2
after this period is
acceptable.
If it is desired to reinstall the camera immediately, inspection of the enclosure seals with a
soap solution may be performed.
1. Mix a solution of 75% water / 25% dish soap.
2. Use a q-tip to apply solution to enclosure seals and around bleed screw and base of
Schrader valve.
3. Apply solution to borders of camera window.
4. If bubbles appear and grow, there may be a leak. Set camera aside and retest with
PSEE™ at a later date.
5. If no leaks are found, clean camera as outlined in manual and return the system into
service
Periodic Maintenance
The camera requires the presence of dry N
2
to prevent ingress of contaminants into the
camera enclosure and eliminate camera video problems due to condensation on the inside of
the window.
1. The camera N
2
levels should be checked every three months.
2. N
2
should be refilled if levels ever drop within 25% of factory empty levels.
3. If the camera exhibits leaks that exhaust N
2
levels quickly, contact RVision for
support.
