In this menu you can do the following:
•
Set the number of samples used for cal
-
culation of various statistical measures.
•
Set the number of bins in the histogram
view.
•
Pacing
The delay between measurements,
called pacing, can be set to ON or OFF,
and the time can be set within the range
2 ms – 1000 s.
Timebase Reference
Here you can decide if the counter is to use an
Internal or an External timebase. A third al-
ternative is Auto. Then the external timebase
will be selected if a valid signal is present at
the reference input. The EXT REF indicator at
the upper right corner of the display shows
that the instrument is using an external
timebase reference.
Miscellaneous
The options in this menu are:
•
Smart Time Interval (valid only if the se
-
lected measurement function is Time In
-
terval)
The counter decides by means of
timestamping which measurement
channel precedes the other.
•
Auto Trig Low Freq
In a value input menu you can set the
lower frequency limit for automatic trig
-
gering and voltage measurements
within the range 1 Hz – 100 kHz. A
higher limit means faster settling time
and consequently faster measurements.
•
Timeout
Switch the Timeout function ON or OFF
(see below).
•
Timeout Time
Set the maximum time the instrument
will wait for a pending measurement to
finish before outputting a zero result.
The range is 10 ms to 1000 s.

Math/Limit
You enter a menu where you can choose be-
tween inputting data for the Mathematics or
the Limits postprocessing unit.
The Math branch is used for modifying the
measurement result mathematically before
presentation on the display. Thus you can
make the counter show directly what you
want without tedious recalculations, e.g. revo
-
lutions/min instead of Hz.
