Peak and Valley Detection (Maximum/Minimum Reading View)
The meter can store the lowest and highest reading values in memory. You can see these
values if you press the MAX/MIN front panel button, or by using remote contact closure switches.
The first press shows peak, with the upper left hand indicator bar lit (marked ‘Max.’). The sec-
ond press shows valley, with the lower left hand indicator lit (marked ‘Min.’). The display returns
to the running value after 2 or 3 seconds. To reset the memory, press the RESET button for more
than 3 seconds while peak or valley is being displayed. Peak and Valley values are not stored if
you switch the meter off.
