Example
The voltage measuring range is set manually to 30 V.
The first measured value is 5 V and is stored to memory because
it is greater than 10% of the measuring range (= 3 V), and is thus
reliable above the background noise level. As soon as the
measured values drops to less than 10% of the measuring range,
i.e. amounts to less than 3 V which corresponds to removal of the
test probes from the measuring point, the instrument is ready to
store a new value.

4.4.1 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

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.

As opposed to the DATA function, the Min/Max function can
also be used for temperature measurement.
