Example
The voltage measuring range is set manually to 10 V. The first meas-
ured value is 5 V, which is stored to memory because it is greater than
10% of the measuring range (= 1 V), and is thus reliably 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 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 Func-
tion
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 momentary 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 (for 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.
