3.5. Max/Min + HOLD
The meter displays the maximum or minimum value of the input in Max/Min mode. When MMX
key is pressed for the first time, the meter displays the maximum value. The meter displays the
minimum value, when it is pressed again. When MMX key is pressed for the third time, the meter
displays current value. The meter returns to normal operation if MMX is pressed and held for longer
than one second. Pressing HOLD in Max/Min mode makes the meter stop updating the maximum or
the minimum value.
