Example
The voltage measuring range is set manually to 10 V.
The first measured value is 5 V and is stored to memory because
it is greater than 10% of the measuring range. As soon as the
measured value drops to less than 10% of the measuring range,
i.e. amounts to less than 1 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.
Apply the measured quantity to the instrument and set the mea-
suring 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 func-
tion 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.
