MIN MAX AVG Recording Mode
The MIN MAX AVG recording mode captures the minimum and
maximum input values, and calculates a running average of all
readings. When a new high or low is detected, the Meter beeps.
To use MIN MAX AVG recording:

For dc functions, accuracy is the specified accuracy of the
measurement function 12 counts for changes longer than
275 ms in duration.
For ac functions, accuracy is the specified accuracy of the
measurement function 40 counts for changes longer than
1.2 s in duration.
Make sure that the Meter is in the desired measurement
function and range. (Autoranging is disabled in the MIN MAX
AVG mode.)
Press MIN MAX to activate MIN MAX AVG mode.

AutoHOLD Modes
In the AutoHOLD mode, the Meter holds the reading on the display
until it detects a new stable reading. Then the Meter beeps, and
displays the new reading.
