Keithley 706 Instruction Manual page 63

Programming Example-Enter the following statements
into the HP85 to program settle time of each channel to
50.05 seconds.
REMOTE 718 (END LINE)
OUTPUT 718; "H50.050X" (END LINE)
When END LINE is pressed the second time, the settle time
of each channel is set to 50.05 seconds. Upon completion of
the programmed settle time the Model 706 outputs a
negative going lTL level pulse of greater than 10pec to the
channel ready output. The pulse can be used to inform
another device or instrument that the programmed settle time
is completed for one channel. To display the settle time on
the controller's display use the six line program in paragraph
3.5.1. Use GIO instead of GO to send the settle time with a
prefix and do not use line 20 (clear). To display the settle time
on the Model 706 front panel activate front panel Program 2.
3. Channel Save/Recall (I) and (Zl
The letter I is the command to save the present relay set up
or recall the stored relay set up. Refer to paragraph 2.9.5
and 2.9.6 (front panel Program 4 and 5) for more informa-
tion concerning saving and recalling relay set up. The for-
mat for the save/recall command is as follows:
IO-clears all memory locations.
101 through 175 save the present relay set up.
ZOI through Z75 recall the corresponding relay set up.
Programming Example-Enter the following statements
into the HP-85 to program the Model 706 to save the present
relay set up.
REMOTE 718 (END LINE)
OUTPUT 718; "11X" (END LINE)
When END LINE is pressed the second time, the Model 706
saves the present relay set up. To recall the stored relay set
up enter the following statements into the HP-85.
REMOTE 718 (END LINE)
OUTPUT 718; "ZIX" (END LINE)
When END LINE is pressed the second time, the Model 706
recalls the stored relay set up.
Programming Example-Use the following program to
store a relay set up of channels 1 through 5 with the program-
med first channel being channel 1, and the programmed last
channel being channel 5. The odd channels are programmed
closed and the even channels are programmed open. Type
the following program into the HP-85:
PROGRAM
IO REMOTE 718 (END

20 CLEAR 7 (END LINE)
30 OUTPUT 718; "Bl Fl

Clears the Model 706.
Displays, closes and sets
channel 1 as the first
channel.

40 OUTPUT 718; "B2N2X" Displays and closes channel
(END LINE) 2.
50 OUTPUT 718; "B3C3X" Displays and opens channel
(END LINE) 3.
60 OUTPUT 718; "B4N4X"
Displays and opens channel
(END LINE) 4.
70 OUTPUT 718; "B5L5C5X" Displays, closes & sets

90 OUTPUT 718;"RX"
(END LINE)
100 END
channel 5 as last channel.
Saves relay set up.
Opens all channels and dis-
plays the first channel.
Press the RUN key on the HP-85 to run the program. After
the RUN key is activated the Model 706 displays the reset
condition.
rim-7-q
Use the following programming statement to recall and
display the stored relay set up.
OUTPUT 718; "Zlx" (END LINE)
This statement and the previous nine step program saved and
recalled one relay set up. With the front panel CHANNEL but-
ton advance through to channel 5 and notice that the set up
was indeed saved then recalled. The Model 706 is capable of
saving and recalling 75 relay set ups. The commands to save
and recall the relay set ups are as follows:
IO save 0 in all locations.
101 saves a set up and ZOI recalls the set up that 101 saved.
102 saves a set up and 202 recalls the set up that 102 saved.
103 saves a set up and 203 recalls the set up that 103 saved.
8, ,I
I;5 sables i sit ip and &5 reialls';heiet u';, that 175 sa(;ed.
It is possible to save a relay set up in any order. For example,
102 can save a set up without having a set up saved by II, 13,
etc.
10. ROM and LED Test (JI
The letter J is the command that programs the Model 706
to go through many of the testing routines that are
automatically performed upon power up. When the self
test command is sent, the following actions are per-
formed:
A. ROM Test
B. LED Test (All front panel LEDs turn on for a short
period of time.)
C. If the tests did not find anything wrong, then the self
test (J) byte in the status word is set to one. If the
test failed then the self test byte (JI is set to two.
The self test command is implemented with the following
command sequence:
