Alarm Function
The MI70 indicator can produce an alarm when a measured quantity is
outside the allowed range. The range is controlled by setting the lower
and upper limits. When the alarm is active, the indicator will show an
alarm message, play a beeping sound, and blink the display backlight.
The alarm can only be set for one quantity at a time. Set the alarm as
follows:
1. Open the Functions menu.
2. Select Alarm.
3. Select the measured Quantity for the alarm. Only quantities that
are currently measured can be selected.
4. Set two limit values for the alarm using the Limit options.
5. Check the Alarm on/off checkbox to enable the alarm. After you
enable the alarm and exit the menu, the alarm symbol will appear
on the display, and flash briefly.

The alarm will automatically turn off if you change the measurement
configuration (change the measured quantities, or connect/disconnect
devices). If you use the alarm function, always check the alarm
settings after changes.
