Automatic Interval Sequence
Automatic execution of a programmed sequence range is above
all advisable if feed to the signal circuit and scanning of the
peripheral device under test are physically separated.
After entering all parameters for the “automatic interval sequence”
output function (see above) (
I nt , mode = auto ), the sequence can
be started and stopped whenever desired, as well as resumed.
Example of an Automatic Interval Sequence
Interval parameters: output quantity: U (range of 0
…
15 V),
start = 2 V, end = 10 V, number of interval steps = 3, t1 = 5 s,
mode = auto
Key
1 When
1nt
ready appears at the display:
Start the sequence by pressing
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
= t1 – t
x
.
4 Stop the interval sequence by pressing the key.
