c) Alarm
The measuring device is equipped with an alarm function on underrunning/exceeding preset
temperature values. The alarm features a signal tone as well as lighting up the display red.
This function makes the measuring device ideal for temperature monitoring, etc.
The device has two adjustable temperature values (upper and lower alarm value). The alarm is
triggered on underrunning the lower alarm value or exceeding the upper alarm value.
Those values can be adjusted and activated independently. The upper alarm limit value,
however, must be higher than the lower alarm limit value.

• Press the laser/backlight button to turn the alarm on or off.
• Press the measuring button to confirm your input or press the MODE button to proceed to
the next setting.
• When the device is switched off, the set value is retained.
