FUNCTI ONAL C H ECK
The following procedure is provided to aid in obtaining
a display on the 608 Monitor and may be used as a
check of basic instrument operation. The procedure
may be used for incoming inspecti on to verify proper
operation, and may also be used by the operator for
instrument familiarization. Only instrument functions,
and not measurement quantities or specifications, are
checked in these procedures. Therefore, a minimum
amount of test equipment is required. If performing
the Functi onal Check procedure reveals i mproper
performance or instrument malfunction, first check the
operati on of associated equipment; then refer to
qualified service personnel for repair or adj ustment of
the instrument.
NOTE
Functional Check Procedures for the

P R E LI M I NARY S ET U P
1 . Install the function generator in the power module
and turn on the power module.
2. Connect the 608 power cord to a suitable power
source.
NOTE
Check the line voltage information recorded
on the rear panel. If the source voltage is
not within this range, refer qualified service
personnel to the servicing information
sections of the 608 Instruction Manual.
3. Open the access door on the front panel and set
the controls as follows:
Vertical and
Horizontal Position . .. . . . . . Midrange
INTENSITY .. . . . .. . , . . . . . . Fully counterclockwise
FOCUS ......... , ........ Midrange
ON/OFF . . . . . .. . . ... . . . . . O N (pushbutton in)
4. Allow at least one minute for the instrument to
warm up.
D I S PLAY F UN CTI ON S
1. Perform the Preliminary Set Up procedure.
2. Notice that a spot will appear on the crt, increasing
in brightness as you slov'.;ly turn the INTENSITY control
clockwise.
�
A high intensity level combined with a
stationary spot will damage the crt
phosphor. Therefore, set the INTENSITY
control to the minimum necessary for good
visibility.
3. Adjust the FOCUS and ASTIG controls for a sharp,
well-defined display.
4. Turn the Vertical and Horizontal Position controls
and notice that the spot pOSition can' be controlled by
