High/Low Temperature Alarm (VT04A, VT04)
High temperature and low temperature alarms are available on the VT04A and
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 (High) or blue/black band (Low). 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.
