Mode control .......................
Note. When the C-D CAGE switch is set to
OFF, the test set will sequence through
level, GC1, and GC2 modes. When the C-
D CAGE switch In set to OFF, the C-D
LEVEL indicator lights. Within 120 ( 12)
seconds, the C-D LEVEL indicator goes out
and the C-D GC1 indicator lights. Within
240 (-24) seconds after C-D GC1 indicator
lights, the C-D GC1 indicator goes out and
the C-D GC2 indicator lights. As soon as
each mode indicator lights, tests relating to
each mode
must be performed within the specified
time. Simultaneously start stopwatch and
set C-D CAGE switch to OFF; then perform
the following steps
a. Observe that C-D CAGE indicator goes
out and C-D LEVEL indicator lights.
b. Set EU SCAN SELECT switch to
DISCRETES.
c. Set EU TEST SET SCAN switch to
positions indicated below, and
observe scope and DVM for voltages
listed.
