6-3.2.5.1
CLEAR.
Command sent to clear LED display
display and decade up/down counter on auto-scaler.
6 - 3 . 2 , 5 . 2 P R I N T .
Command sent to signal calculator
TM5-6675-326-14
on calculator and LED
to implement
i n s t r u c t i o n s o f s u b r o u t i n e E,
stored in memory, which prints the pulse
count data.
P R I N T a l s o i n i t i a t e s t r a n s m i s s i o n o f t h a t d a t a f o r p r i n t i ng
when auto-scaler is in MAN.
6 - 3 . 2 . 5 . 3 I N I T .
Command sent to signal calculator to implement sub-
routine D, which resets memory data registers for the next set of data.
6-3.2.5.4 X MEMORY.
Has four settings:
1, 2, 3, and 4. Tells the
calculator which primary register memory location (1, 2, 3, or 4), and its
contents, is to be used in calculations.
6-3.2.5.5 MAN/AUTO.
Determines the mode of data transmission for the
a u t o - s c a l e r .
6-3.2.5.6 B/ACCU/A/OFF.
Controls the operating status of the decade
up/down counter.
There are four possible settings:
OFF, A, ACCU, and B.
OFF turns the auto-scaler OFF.
A enables the decade up/down counter to
increment the count, B enables it to decrement the count, and ACCU freezes
the decade up/down counter at its current total.
6 - 3 . 3 C a l c u l a t o r .
Performs manipulations and calculations on pulse count
data, prints results and intermediate steps in the proper units on
command, and stores data and programs.
There are six functional parts:
memory, logic circuitry, keyboard, LED display, magnetic card reader, and
p r i n t e r .
6-3.3.1 Memory.
Stores pulse count data, constants, results of calcula-
tions, and subroutines containing programmed instructions (for using pulse
count data and constants).
In order to use the QPS, the programs with
i n s t r u c t i o n s f o r p e r f o r m i n g c a l c u l a t i o n s a r e e n t e r e d i n t o t h e c a l c u l a t o r
memory.
The memory is divided into three parts:
automatic memory stack,
storage registers, and program memory.
6-3.3.1.1 Automatic Memory Stack.
Has four available locations (X, Y, Z,
and T) which are used by the operator and the calculator in performing
c a l c u l a t i o n s .
The logic circuitry uses the automatic memory stack in
performance of its instructions and to store intermediate results of
c a l c u l a t i o n s .
6-3.3.1.2 Storage Registers. Used to store special numbers such as pulse
counts and constants.
Each register can hold one constant number or
command.
P r i m a r y r e g i s t e r R1 is directly connected to the calculator
i n t e r f a c e c i r c u i t r y i n t h e a u t o - s c a l e r.
Contents of storage registers are
affected only by the keyboard or program command.
The INIT signal begins
a program which commands the calculator to clear the storage registers.
The storage registers are divided into two parts:
16 primary registers
