When the RUN key is pressed, the alarm time is set for 2:15 pm.
The alarm time is also displayed on the HP-85 CRT.
NOTE
When the format of the programmed
time is not the
full six digits (hh:mm:ss)
the Model 705 truncates
the time to what is programmed.
If in this example
the last two zeroes were left out the time would be
programmed
for 14 minutes
15 seconds
AM. The
colons between
the hours, minutes and seconds
are optional.
18. 18. Reset
(R)
The letter R is the command that programs the Model 705 to
reset conditions. The reset conditions
are: all channels open
and display the specified first channel.
Programming Example
-
Enter the following
statements
into
the HP-85 to reset the Model 705.
REMOTE 717 (END LINE)
OUTPUT 717; "RX" (END LINE)
When the END LINE key is pressed
the second
time, the
Model 705 goes to the reset condition.
NOTE
The first channel was set to 5 in a previous exam-
ple. When the END LINE key is pressed the sec-
ond
time
the
Model
705
should
display
the
following:
Ius

19. Set Time (S)
The letter S is the command
to program the Model 705 to
set the time. The format is as follows:
Shh:mm:ss
where
S = Set Time Command
h = Hours
m = Minutes
s = Seconds
Programming Example
-
Enter the following
statements
into
the HP-85 to set the time to 5:00 pm.
REMOTE 717 (END LINE)
OUTPUT 717; "D2S17:OO:OOX" (END LINE)
When the END LINE key is pressed
the second
time, the
Model 705 displays the time and sets it to 5:00 pm.
NOTE
When the format of the programmed
time is not the
full six digits (hh:mm:ss)
the Model 705 truncates
the time to what is programmed.
If in this example
the last four zeroes are left out the time would be
programmed
for 17 seconds
not 5:00
pm. The
colons between
the hours, minutes and seconds
are optional.
20. Trigger Modes (T)
The trigger commands
control the stimulus to be used to
start or stop Model 705 program
operation.
Basically,
the
trigger StimUkIS Controls instrument
operation
much like the
front panel START/STOP button does, except that the trig-
ger stimulus
can COntrOl either
start or stop (not both),
depending
on the selected trigger mode. Model 705 trigger
modes are:
TO -
Start on Talk
Tl -
Stop on Talk
T2 -
Start on GET
T3 -
Stop on GET
T4 -
Start on "X"
T5 -
Stop on "X"
T6 -
Start on External
T7 -
Stop on External
NOTES
1. In the
step
(manual)
program
mode,
the
instrument
advances one channel location with each trigger stimulus.
2. When the instrument
is triggered to start, program execution
begins at the present channel location.
Programming Example

exam-
ple the Model 705 is programmed
