proceed. The three dots may also appear following the mode change.
Wait until the dots disappear.
Hold CAM 1/2 inch away and monitor object in G Mode.
(8) If the operation of the CAM is in doubt at any time, the
filtered nozzle standoff should be removed and the protective cap
assembly replaced on the nozzle assembly. When the display has
is removed and a new filtered nozzle standoff installed. A confidence
test is performed and monitoring can then continue.

environmental cap when CAM is in use to prevent the inside of the
nozzle protective cap assembly from becoming contaminated.
(2) DO attach the nozzle protective cap assembly on the
nozzle assembly when:
Preparing CAM for operation.
Clearing CAM down.
Preparing CAM for shutdown.
(3) DO install a clean filtered nozzle standoff before
monitoring with CAM.
(4) DO ensure that the filtered nozzle standoff is moved
close to, but does not touch, surfaces being monitored.
DO protect the filtered nozzle standoff from driving rain
(6) DO install a clean filtered nozzle standoff, if one in
use becomes contaminated or wet. Rain or condensation building up on
the filtered nozzle standoff may also rise to misleading readings. It
may, therefore, be necessary to change the filtered nozzle standoff
from time to time when operating under these conditions. Condensation
is most likely to form when the CAM is cooler than the surrounding
air, especially in humid conditions such as tropical zones.
DO establish areas of clean air.
(8) DO work from clean areas into dirty areas whenever
possible and, thus, minimize the time spent in dirty areas.
