Automatic Interval Sequence
Automatic execution of a programmed sequence range is
above all advisable if feeding to a signal circuit, and scanning
of the peripheral device under test are physically separated.
After configuring all parameters in accordance with the menu
flowchart on page 13 for the “automatic interval sequence”
(Int, Auto = yes), the sequence can be started, and stopped
or continued at any desired time.
Example of an Automatic Interval Sequence
Interval parameters:
Output quantity: U (0 … 15 V range),
Start =2V, End = 10 V, number of interval steps = 3, t1 = 5 s,
auto = Yes (yes for automatic sequence)
Key
:
1 The sequence is started by pressing the ↵ key when Int
start is displayed (see Menu Flowchart on page 12).
2 The sequence is stopped by pressing the " or the #
key. Interval time elapsed thus far is saved as t
x
.
3 The sequence is resumed by pressing the " key, and
remaining sequence duration t
y
is equal to t1 – t
x
.
4 Stop the interval sequence by simultaneously pressing
and holding the " and the # key (2 audible acoustic sig-
nals must be generated).
