Operation 2-5
The PROG Step Light should indicate 2, and the frequency and level for that
segment should show up on the indicators. It is also possible to increment the
segments by pressing the following keys:
This would move to the next segment and pressing:
would move to the previous segment.
Each segment has a dwell time associated with it. This time can be any number
between 1 to 9 seconds. This is used when the unit is programmed to step
through the 31 different segments, and dwell at each segment for the
programmed dwell time duration.
Press
and it shows the dwell time for that segment (it should
indicate 1 to 9.). If a new dwell time is desired, press any key between 1 and 9 to
change it to a new time, otherwise press
.
Once all of the 31 different segments have been programmed; the operator can
cause the 346B to step through each segment and dwell at each segment for the
preset time duration. This can be done either through the keypad or by using the
two terminals on the back panel.
the keypad, press
, and it will start the sequence. Press
again, and it will stop the sequence.
If there are less than 31 segments, set the dwell time for the segment after the
last segment for 0. For example, if there are only 10 segments, set the dwell time
for segment 11 for 0 second, and it will step through segments 1 through 10 and
then it will stop.
Remote
From the remote, apply +5 Volts to the ST/ST Terminal and it will start the
sequence. If you remove the +5 Volts, it will stop the sequence. Also if you apply
+5 Volts to the RESET terminal, it will move to the first segment on the program.
Therefore, if the test needs to start at segment one, first apply the +5 Volts to
RESET, then remove it and apply the +5 Volts to the ST/ST terminal.
