50-70
cycle
line.
Turn

ON
and
adjust
it
un-
til the needle on the meter face is directly in line with LINE TEST. Set
the front panel controls according to the data on the roll chart. After the

panel
controls
have
been
set,
place
the
tube
to
be
tested
into
the
proper socket. Allow at least 30 seconds for the tube to achieve its oper-
ating temperature.
2-5 TEST PROCEDURES
CAUTION
Do not insert tube to be tested into test socket
until correct settings of all controls have been
made,
а, FILAMENT CONTINUITY TEST
After the FILAMENT voltage selector and the two FILAMENT
SELECTORS аге set, the tube to be tested сап be inserted into the proper
test socket. Adjust the POWER LINE ADJUST until the needle on the
meter is directly over LINE TEST on the meter face. To check the con-
tinuity of the filaments of the tube under test, depress the button marked
FILAMENT CONTINUITY. If the filaments of the tube under test are
good, the needle on the meter will remain near LINE TEST, and if they
are open, the needle will drop back to zero.
