j. Adjust test oscillator set for a 30 mv output
at 400 Hz, using as a reference the 400F/FL
meter indication obtained in step d of this
paragraph. Set a reference on meter of test
oscillator and use amplitude control to main­
tain the set reference whenever frequency of
osc11lator is varied.
k. Repeat step d of this paragraph for each fre­
quency Hsted in Table 5-2 (400F) or Table
5-3 (400FL).
m. Perform steps eandfof this paragraph, main­
tainingthe output amplitude of the test oscil­
lator at 30 my.
n. Repeat step d of this paragraph for each fre­
quency listed in Table 5-2 (400F) or Table 5-3
(400FL).
o. Set 400F/FL RANGE sw.itch tol volt, and dis­
COlUlect shorts between test paints.

meter indication obtained i n step h of this
paragraph.

5-14. RANGE TRACKING CHECK.
5-15. After verifying the 400F/FL full scale calibra­
tion with the accuracy and frequency response tests,
check the range tracking of the instrument with the
following procedures. Use the test setup shown in
Figure 5-1 for the range tracking check.
a. Set switch SI to Position A.
b. Set 400F/FL RANGE switch to 30 mv.
c. Adjust test oscillator for a 400F/FL meter
indication of 30 mv at 400 Hz.
