The purpose of these procedures is to confirm that this oscilloscope functions
properly. The only equipment required is one of the standard-accessory
probes and, to check the file system, a 3.5 inch. 720 K or 1.44 Mbyte floppy
disk.

These procedures verify functions; that is, they verify that oscillo-
scope features 

operate. They do not verify that they operate within

limits.

Therefore, when the instructions in the functional tests that follow call
for you to verify that a signal appears on-screen “that is about five
divisions in amplitude” or “has a period of about six horizontal divi-
sions”, etc., do 

NOT interpret the quantities given as limits. Operation

within limits is checked in 

Performance Tests, which begin on

page 1-15.

DO NOT make changes to the front-panel settings that are not called
out in the procedures. Each verification procedure will require you to
set the oscilloscope to certain default settings before verifying func-
tions. If you make changes to these settings, other than those called
out in the procedure, you may obtain invalid results. In this case, just
redo the procedure from step 1.

When you are instructed to press a menu button, the button may
already be selected (its label will be highlighted). If this is the case, it
is not necessary to press the button.
