Min–Max Operation
The min-max operation stores the minimum and maximum readings
during a series of measurements. The multimeter then calculates the
average of all readings and records the number of readings taken since
min-max was enabled.
Applies to all measurement functions, except continuity and diode.
•
After you enable min-max, the first reading that the multimeter
takes is stored as both the minimum and maximum value.
The
minimum is replaced with any subsequent value that is less.
The maximum is replaced with any subsequent value that is greater.
•
The multimeter displays “
MIN
” or “
MAX
” and beeps (if the front-panel
beeper is enabled) whenever a new minimum or maximum is found.
It is possible that the multimeter will beep even if the displayed
reading does not change; this is because the multimeter’s internal
resolution may be greater than the displayed resolution.

“Beeper Control,” on page 88.
•
The minimum, maximum, average, and count are stored in volatile
memory; the multimeter clears the values when min-max is turned on,
when power has been off, or after a remote interface reset.
•
Front-Panel Operation : After enabling min-max, you can read the
stored minimum, maximum, average, and count by pressing
Shift >
(Menu Recall). Turning on the menu does not disable
the min-max operation; the multimeter will resume taking
measurements when you turn off the menu.
