the operator to select the outputs of the comparators (ordinally
CPO through C?8).
The two reference voltages
are selected only by pushing the
buttons designated 100 (red, for positive)
or 100 (Utue, for
negati-ve), nevertheless any button of the second, row depressed.
The button designated D(l- perrait the operator to call
an external
signal from an exbernal device,
for instance
the output selector
in the additional
computing eonsole CS-505A. A button designated
EX2 has no con:rection and is provided as a spare selector.
Depressing the button,
one of AO through L3, sets the select-
or system for arnplifiers
in a gi-ven tens groupr i.e.,
if
the
button designated A1 is depressed, amplifiers
AIO through A19 are
set up for sel-ection.
The button in the second row designates which
of these ten amplifi-ers is actually
selected.
The selector
system
button numbering corresponds with the amplifier
and comparator
designations as marked on the pre-?atch ?anel respectively.
The selector
system output is connected to the ten terrninations
marked SBL in the upper portion
of the Readout ?ane1 0C_151 (tr'igure
1. J-r )
fn order to read out a selected
signal
on the pvM, the ieft
bottl-e plug sholm in Figure 2.2-2 must be in p1ace.
The nrirlti-
range voltmeter
(vu) may al-so be connected to the selector
line
by
installing
the correct bottl-e plug shor,rn in the ill_ustration.

should be noted, however, that the w
circuit
will_ load the output
of the selected component with a relatively
1ow impedance and should
not be used if
the circuit
cannot tolerate
this
load.
