up was stored and then the Model 706 was reset by using the
RESET button. This is the point where we will start the exam-
ple of Program 5. To recall the stored relay set up, use the
following
procedure:
1.
2.
Press RESET. Reverts instrument
to programmed first
channel and opens all channels.
Press PRGM, 5. Selects program mode and also Program
5. After the 5 button is pressed the Model 706 displays the
following:
/I
This display indicates that the recall program has been
activated. The display prompts the user for the specific
_ relay set up that is stored (1 through 751.
3. .Press 0, 1, ENTER. Selects relay set up number 1 to be
recalled and when ENTER is pressed the set up is recalled.
4.
After ENTER is pressed, the Model 706 recalls relay set up
number 1 and displays the channel that was shown
previous to pressing PRGM. In this case, the following is
displayed because step 1 reset the display to the program-
med first channel.

..-.:
In order to verify that the stored set up was recalled pro-
ceed to step 4.
Press CHANNEL nine times and notice that the odd
numbered channels are closed and the even numbered
channels are open. This shows that the stored relay set up
was indeed recalled by Program 5.
The factory set values of Program 5 are all channels open
and the programmed first and last channels are set to 1.
Program 5 also works in the matrix mode, refer to
paragraph 2.9.13 for an example.
In the matrix mode of operation pressing the START/STOP
button displays the Recall display along with the present
memory location. Pressing the START/STOP
button in the
matrix mode and while the recall display is shown, advances
the instrument to the next memory location. Pressing the
CHANNEL button while the recall display is shown, selects
the channel display mode. By repeatedly pressing the CHAN-
NEL button the crosspoints of that memory location are
displayed. If in the inspect mode, all the closed crosspoints
can be displayed (one at a time, not simultaneously).
Refer to
paragraph 2.9.13 for inspect mode information.
Pressing the START/STOP
button repeatedly to advance
through the stored memory locations is an easy way to locate
a desired memory location. This procedure will go through all
the stored locations up to location 75 or to where a memory
location has been cleared (Program 94Ior to the last stored
memory location and then loop back to memory location 01.
If memory location 01 was cleared using Program 94, attemp-
ting to recall the location is not valid and cannot be recalled.
This is true for all the locations.

6 Pole Configuration
Program 6 is used to program the desired number of
measurement poles or to select the matrix mode.
Measurement
Poles-The
Model 706 permits either 1,2 or
4-pole measurements. Table 2-18 contains a list of the dif-
ferent scanner cards and which pole configuration
to use
with each scanner card.

The l-pole configuration can be used by operators who need
to switch just one (HI) side of their configuration.
The 2-pole
configuration
can be used for normal measurements. The
Cpole configuration
can be used for 4-terminal ohms or a
switched HI, LO COM and Guard measurement. The matrix
mode (O-pole on the Model 706) can be used to switch any
one point to another.
The pole configuration
is displayed by activating Program 6.
The pole configuration
can be changed by activating Pro-
gram 6 and pressing the desired number (0, 1,2 or 4). For ex-
ample, use the following
procedure to change the present
pole configuration
to 4.
1. Press PRGM, 6. Selects Program 6 and displays the

NOTE
Upon the actuation of front panel Program 99,
the Model 706 sets the pole configuration
to 2.
Power up does not affect the pole configuration.
2. Press 4, ENTER. Loads 4 onto the display and when
ENTER is pressed, the pole configuration
is set to 4. The
Model 706 then reverts to the channel mode, turns on the
channel LED and dislays the programmed first channel.
NOTE
Before pressing the ENTER button in step 2, the
Model 706 ignores the entry of any invalid
number (3, 5, 6, 7, 8, 9) for this program.
To verify that the pole configuration was changed to 4, press
Program 6, and the display shows that it was changed to 4.
Now change the pole configuration to 2. This can be done by
