When Min/Max is enabled, pressing
steps through the various Max,
Min, Avg, and N values in the secondary display. Count values display in
integer format until the maximum display value (120000) is reached after
which counts are displayed in scientific notation.
Limit
The Limit operation allows you to perform pass/fail testing against
specified upper and lower limits. You can set the upper and lower limits
to any value between 0 and
\
120% of the highest range for the present
function.
•
You should specify the upper limit to always be a more positive number
than the lower limit. The initial factory setting for each limit is
0
.
•
The secondary display shows
PASS
when readings are within the
specified limits. The secondary display shows
HI
when the reading is
outside the high limit and
LO
when the reading is outside the low limit.
•
When the beeper is ON (see
“Using the Utility Menu”
on page 36) the
beeper beeps on the transition from
PASS
to
HI
or
PASS
to
LO
or
when transitioning directly from
HI
to
LO
or
LO
to
HI
(no
PASS
in
between).
You can view and edit HI Limit and LO Limit values in the secondary
display as described in
“Editing Values in the Secondary Display”
on
page 40.
Hold
The reading hold feature allows you to capture and hold a stable reading
on the front panel display. When a stable reading is detected, the
multimeter emits a beep (if the beeper is enabled) and holds the reading
on the primary display. The secondary display shows the present reading.
When enabled, the Hold operation turns on the
Hold
annunciator and
begins evaluating readings using the rules described below:
Primary Display = Reading
