Minimum and maximum values
For the most measured values (see table measured
and calculated quantities) the minimum and
maximum values are saved. The minimum value is
the smallest measured value, which was detected
since the last deletion. The maximum value is the
biggest measured value, which was detected since
the last deletion. Every measured value is
compared to the saved minimum and maximum
values, which are overwritten in case of exceeding.
For each minimum and maximum value, the first
existance is saved with date and time.
After return of supply voltage, all minimum values
are deleted automatically.
Minimum values are marked with an arrow
downwards and maximum values with an arrow
upwards.
The maximum value of the current mean value, for
example, is indicated as follows:

When the device is delivered, most of the minimum
and maximum values can be called up via the keys
1 and 2. If you are interested in date and time of the
minimum and maximum values, this information can
be called up by the
SELECT
function.
All minimum and maximum values can be deleted
all together or individually with the function
PRG
.
On 25.10.1998 at 08:10:31 appeared the maximum
measured value of current in L2 since its last
deletion.
Press
key 1 for about 2 seconds and you return to
the first measured value window of the measured
value indication from each program part.
