Each time a new minimum or maximum value is stored, the 
instrument beeps once (if the beeper is enabled) and briefly 
turns on the appropriate Max or  Min annunciator. The 
multimeter calculates the average of all readings and records 
the number of readings taken since Min/Max was enabled.
• Accumulated statistics are:
• Max- - maximum reading since Min/Max was enabled
• Min- - minimum reading since Min/Max was enabled
• Avg- - average of all readings since Min/Max was enabled
• N- - number of readings taken since Min/Max was enabled
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 41) 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).
