4.4.2 Saving Minimum and Maximum Values – MIN/MAX Function
Minimum and maximum measured values applied to the
measuring instrument’s input after the Min/Max function has been
activated can be “frozen” at the display. The most important use
of this function is the determination of minimum and maximum
values during long-term measured value observation.
The Min/Max function can be activated in all measuring functions.
The Min/Max function has no effect on the analog display, at
which the current measured value continues to appear.
Apply the measured quantity to the instrument and set the
measuring range with the MAN / AUTO key before activating the
Min/Max function.
The Min/Max function is deactivated by pressing and holding the
DATA/MIN/MAX key (approx. 1 second), when the measuring
function is changed or when the instrument is switched off and
back on again.
Note
As opposed to the DATA function, the Min/Max function can
also be used for temperature measurement.
