Saving Minimum And Maximum Values - Min/Max Function - Gossen MetraWatt METRAHIT PM TECH Operating Instructions Manual

Example
The voltage measuring range is set manually to 6 V.
The first measured value is 3 V, which is stored to memory
because it is greater than 5,000 digits of the measuring range
(= 0.5 V), and is thus reliably above the background noise level.
As soon as the measured values drops to less than 5,000 digits
of the measuring range, i.e. amounts to less than 0.5 V which
corresponds to removal of the test probes from the measuring
point, the instrument is ready to store a new value.
6.4.1 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
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.
