Minimum and Maximum Value Storage
Minimum and maximum values which occur at the measuring
instrument input after the MIN/MAX function has been activated
can be “frozen”. The most important application for this function is
the determination of minimum and maximum values for long-term
observation of measured quantities.
MIN/MAX has no effect on the analog display, from which you can
continue to read the current measurement value.
Apply the desired quantity to the instrument and select the measur-
ing range before activating the MIN/MAX function.
If the function has been activated, measuring range selection can
only be accomplished manually. However, this causes the deletion
of currently stored minimum and maximum values.
The MIN/MAX function is deactivated by pressing and holding key
DATA|MIN/MAX
(approx. 1 s), by turning the rotary switch or by
switching the instrument off and back on again.
