Tab. 8.13: Differing key assignments
In AutoA-mode ON
the instrument proposes a number of values for A according to an internal
table (6, 10 or 12 points per decade). Manual corrections are possible according to the setting of
AutoA.
In AutoF-mode
, the instrument will perform
subsequent measurements at different
frequencies
.
The proposed number of
points per decade
(P/DEK) and the
frequencies
are selected under
“Settings“ “Acquisition“

8.2.3 Automatic mode
In automatic mode, the instrument will set the correct output current automatically:
The current is increased until the minimum input voltage is reached. The instrument then
repeats the measurement until the preset accuracy (max. error of U0 or U90 falls below
the preset value) or the maximum number of averages (MaxAv) is reached.
The subsequent measurements will start with the settings of the last acquisition cycle.
The instrument increases or reduces the output current, if necessary.
If "Auto ON" was selected, the instrument will enter
the menu "Auto Settings".
At this
point
you set the minimum input voltage and the termination criteria
for the
measurement, e. g. the error of U0 / U90 and the maximum number of averages.
