Control Functions
Example
The voltage measuring range is set manually to 3 V. The first mea-
sured value is 2.2 V and is stored to memory because it is greater
than 5000 digits of the measuring range (= 0.3 V), and is thus reli-
ably above the background noise level. As soon as the measured
value drops to less than 3000 digits of the measuring range, i.e.
amounts to less than 0.3 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 measur-
ing instrument’s input after the Min-Max function has been acti-
vated can be “frozen” at the display. The most important use of
this function is the determination of minimum and maximum val-
ues 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.
