OPERATING INSTRUCTIONS
AMBI E NT TEMP E RATU R E
C O N S IDE RATI O N S
This instrument can be operated where the ambient
air temperature is between 0° and +50° C (+32° and
+ 1 22° F), and can be stored in ambient temperatures
between -40° and +70° C (-40° and +1 58° F). After
being stored in temperatures beyond the above
operating limits, allow the chassis temperature to
return to within the operating limits before applying
power. Allowing the Monitor to operate at an ambient
temperature su bstantially higher than that specified
may result in poor reliability as well as inaccurate
performance.
When the 608 is mounted in a rack with other
equipment, it is i mportant that the a mbient
temperature surrounding the Monitor does not exceed
+50° C (+1 22° F). Additional clearance or forced
ventilation m ethods (fan) may be needed to m aintain
a mbient temperatures below +500 C (+1 220 F).
R eliability and performance of the 608 will be affected
if the ventilation h oles in the protective panels are
obstructed, or if the 608 is operated at an ambient
temperature higher than +500 C (+1 220 F). Other
environments and mounting configurations may
require additional cooling m easures.

Controls and connectors necessary for operation of the
608 Monitor are located on the front and rear panels
of the instrument. To make full use of the capabilities
of this instrument, the operator should be fam iliar
with the function and use of each external control and
connector. The front-panel controls are shown and
described in Figure 2-1. Brief descriptions of the rear
panel controls and connectors are given in Figure 2-2.
NOTE
Information on controls and connectors for
the available options is located in the
Instrument Options section of this manual.

T h e horizontal (X) and vertical (Y) deflection factors are
set at the factory to one volt for eight divisions of
deflection on each axis. Thus, as shipped, the inpu t
signal required for each division o f deflection i s 0.125
volt.

NOTE
The Functional Check procedure may be
used to determine if the horizontal and
vertical deflection factors of your particular
instrument meet those set at the factory,
as stated above.
The best transient response from the 608 M onitor is
achieved w hen the input Signal amplitude to the
vertical or h orizontal INPUT is no greater than that
sufficient to provide full-screen deflection.
WARNING
To avoid electric shock, do not apply input
signals of more than
25
volts (de plus peak
a c). Should fault conditions occur however,
the instrument is protected for application
of input signals up to
100
volts (de plus
peak a c).
With no signals applied to the +Z INPUT connector,
the intensity of the display is controlled only by the
front-panel I NTENSITY control. To control the display
intensity with an externally applied signal, set the
INTENSITY control to about midrange, and apply the
input Signal to the +Z INPUT connector.
�
Exercise care in establishing the correct
display intensity; a high-amplitude Z-Axis
input signal, combined with an excessively
high setting of the INTENSITY control, may
damage the crt phosphor.
The inpu t signal required for maximum display
intensity, thro ugh the +Z INPUT connector, is set at
the factory for +1 volt, or less. The input signal
required to visually cut off the display intensity is set
at the factory for - 1 volt, or less. The best transient
response of the Z-Axis A mplifier is achieved w hen the
input signal is the minimu m required to provide the
desired intensity change.

available options is located in the
