PROCEDURE

1. Prelim inary Check

Install the Type CA Unit in the oscilloscope.

Turn  on  all  the  test  equipment  and  allow
15  minutes  fo r  it  to  warm  up.  Set  the o s c illo
scope  Controls  as  follows:

B efore installing the Type CA Plug-In Unit

in the oscilloscope, make a careful visual
inspection of the w ire dress. This

is par-

ticularly important if any soldering has been
done to the unit. Then make the following
