2.19 CALIBRATION (CAL) (Continued)
Activating the CAL menu item from the Main Menu allows
the operator to turn automatic shuttered calibrations on or off
as shown in Figure 2-12.
Figure 2-12. CAL Menu Options.
AUTO CAL ON
With AUTO CAL ON activated, a shuttered calibration is
automatically initiated upon selection, at least once every 30
minutes, and when the LWTS senses a significant ambient
temperature change; but not more often than once every 30
seconds.
The operator may want to optimize the thermal image more
frequently than the AUTO CAL ON parameters allow. For
this reason, even with AUTO CAL ON enabled, a manual
shuttered calibration can be initiated at any time by
simultaneously pressing the + sides of both the GAIN/EL and
LVL/WND rocker switches.
AUTO CAL OFF
With AUTO CAL OFF activated, all calibrations of the LWTS
must be manually initiated as described above.
