Entering Numeric Values - Fluke PM6690 Operator's Manual

Using the Controls
Numerical
Fig. 2-4 Statistics presented numerically.
In this mode the statistical information is dis-
played as numerical data containing the fol-
lowing elements:
•
Mean: mean value
•
Max: maximum value
•
Min: minimum value
•
P-P: peak-to-peak deviation
•
Adev: Allan deviation
•
Std: Standard deviation
Histogram
Fig. 2-5 Statistics presented as a histo-
gram.
The bins in the histogram are always
autoscaled based on the measured data. Lim-
its, if enabled, and center of graph are shown
as vertical dotted lines. Data outside the limits
are not used for autoscaling but are replaced
by an arrow indicating the direction where
non-displayed values have been recorded.
2-8 Description of Keys
Trend Plot
Fig. 2-6 Running trend plot.
This mode is used for observing periodic fluc-
tuations or possible trends. Each plot termi-
nates (if HOLD is activated) or restarts (if
RUN is activated) after the set number of
samples. The trend plot is always autoscaled
based on the measured data, starting with 0 at
restart. Limits are shown as horizontal lines if
enabled.
n
Remote
When the instrument is controlled from the
GPIB bus, and the remote line is asserted, the
presentation mode changes to Remote, indi-
cated by the label Remote on the display. The
main measurement result and the input set-
tings are displayed in this mode.

Entering Numeric Values

Sometimes you may want to enter constants
and limits in a value input menu, for instance
one of those that you can reach when you
press the MATH/LIMIT key.
You may also want to select a value that is not
in the list of fixed values available by pressing
the UP/DOWN arrow keys. One example is
Meas Time under SETTINGS.
A similar situation arises when the desired
value is too far away to reach conveniently by
incrementing or decrementing the original
value with the UP/DOWN arrow keys. One
example is the Trig Lvl setting as part of the
INPUT A (B) settings.
