Setting Alarm Limits

When you adjust alarm limits, the lower alarm limit appears in blue text in the information zone and upper alarm limit appears in red text in the information zone. The low alarm indicator () and high alarm indicator () also move on the temperature scale.

When you scan a target that registers a temperature exceeding one of the alarm limits:

•A blinking alarm indicator appears on the Imager display

•If the center pixel target temperature exceeds the alarm limit, the center image will blink and alarm value turns bold blue or bold red depending on which limit has been exceeded.

The default low alarm limit is -10 °C (14 °F) and the default high alarm limit is

350°C (662 °F).
