Displaying a Min Max Record

Press to record the maximum (MAX), average (AVG),
minimum (MIN), and difference (MAX-MIN) readings of the
main (upper displayed) measurement. The test tool also
continues to display the present reading. Time stamps
appear next to the MAX, AVG, and MIN readings to show
the elapsed time in hours, minutes, and seconds since the
Min Max start to the most recent change in the respective
reading. The AVG time stamp updates continuously. The
MAX and MIN time stamps update only when new high or
low readings are encountered.
NOTE
A beep occurs when a new MAX or MIN value is detected.
New MIN, MAX, and AVG readings are then updated on
the display.

Displaying the Min Max TrendPlot™

The test tool also continuously logs the maximum, average,
and minimum readings to memory and displays all three as
graphs. Vertical scaling and horizontal time compression
are automatically resized to fit the TrendPlot on the display.
The TrendPlot is slowly traced on the display from left to
right until the screen is written and the time scale is
resized. The initial time scale is 15s/DIV; after a full screen
the scale is compressed to 30s, 1 min, 2 min, etc, to a
maximum of 40 days over a whole display.
