Philips 6652C - Stored Panel Programs

-·- STORED PANEL PROGRAMS
Introduction
Stored panel programs are of great assistance to
those users who have repetitive tasks to per-
form, and/or if the measurements require compli-
cated control configurations.
A stored panel program is stored in a non-vola-
tile memory with a ·retention life of at least
ten years, Eight programs can be stored, and
they are identified by the titles P1 •• • P8. Each
of them can contain a full panel set-up and set
values, with the following exceptions:
READ, ENTER, and STORE cannot be set "ON".
The potentiometer trigger level values cannot
be stored but potentiometer triggering can be
selected by specifying AUTO and KEYBOARD
"OFF".
No HOLD OFF value can be stored. But HOLD OFF
"ON" can be specified.
No external reference signal can be speci-
fied.
In P7 and PB only, neither MATH on nor mathe-
matical constants can be stored,
Stored panel programs can be initiated and crea-
ted over the IEEE 488 bus.
Creating stored panel programs
To create a stored panel program first set all
the controls and values (KEYBOARD trigger le-
vels, measuring time and the K and L MATH con-
stants as required). Select the function, then
press STORE once. The P1 indicator will be lit.
Step the cursor down to the desired program num-
ber, then press STORE again. Any program that
previously existed in that area will be over-
written completely.
NOTE: It is recommended that. P1 is used as a
"work area", rather than as a permanentl y
stored program. This means that when there
is a complex t temporary set up in use, i t
can
be stored in P1. Any accidental power
off or line failure will not, then, de-
stroy t he set up.
Overriding
stored panel p,r'o.grams
When a stored panel program is recalled, all the
controls, indicators and values will be set ex-
actly as they where when the program was created
(except as specified in the introduction). The
program controls and values can be overridden
temporarily by setting other controls and va-
lues. This "real time" selection will last as
long as the power remains on, or until the pro-
gram is reselected. Exceptions to this rule are:
- ARMING/AVG/EXT GATE/OFF and SLOPE. If any of
these facilities was chosen when the program
was created, that facility will appear as the
default when the program is reselected what-
ever the current position of the switch. Mov -
ing the switch while the program is active
will give the ARMING/AVG/EXT GATE facility
which is displayed on the front panel.
Measuring time. The measuring time set by the
program when the program is reselect.ed is that
which was set when the program was created,
whatever the current position of the measuring
time
potentiometer. An override measuring time
can be set by rotating the potentiometer . Note
that to guard against inadvertent movement of
the potentiometer, a movement of 1 decade of
the potentiometer is required. Once these
limits are exceeded, the potentiometer assumes
its full analogue range.
