Displaying Maximum, Minimum, and Peak-to-Peak Readings
The
MAX, MIN, and PKPK menus have the same format and show information derived
from measurements taken since the
Min, Max, or Pkpk mode was reset.
Once one of the three menus has been entered, you can select either of the other two
without going through the
MONITOR menu.
MAX or MIN can be cleared by its own Reset soft key, but the Reset soft-key on the
PKPK menu clears both the Max and Min memory.
In
DCV and DCI, the MAX value is the most positive (or least negative) measurement and
the
MIN value is the most negative (or least positive) measurement.
Note
Because
Pkpk does not store a value except as a result of calculating the
difference between a maximum and a minimum value, if the
MAX or MIN
memory is cleared, the PKPK menu value is also cleared until the first
measurement enters the cleared memory. After this, the
PKPK menu value
reflects the change by showing the new difference between the maximum and
minimum values.
The Multimeter does not clear the
MAX or MIN values upon a change of
function, range, or other measurement parameter. These can be cleared only
by pressing the appropriate
Reset key.

Limit-Checking
Select the
Limit key to display whether high and low limits that were previously set, have
been exceeded by the most recent measurement.
The display indicates a
HI LIMIT if the most recent measurement is above the high limit
of a preset range,
LO LIMIT if it is below the low limit, or PASS if it is within the limit
range.
Limits can de defined from the LIMIT menu, or from MONITOR CONFIG Menu.
