Hi/Lo Temperature Alarm (VT04)
High temperature and low temperature alarms are available on the VT04. The
temperature threshold is set for either the high or low alarm. When an alarm is
set, you can quickly scan the scene and find objects that are above or below the
threshold. An alarm condition is clearly shown on the screen as a flashing
red/black band (Hi) or blue/black band (Lo). See Figure 10. In accordance with
the D:S ratio (see Table 5), the object size should be large enough to cover the
area defined by the 4 corner markers.
