Corrective measure
on 0-10 DB scale. The total
reading in db is the sum of the
meter reading plus the difference
between the final setting
of the RANGE-DB switch and
its initial setting in 21 above.

meter needle reads on-scale.
test
Note reading in db on 02 DB
scale. Total reading in db is
the sum of the meter reading
plus the EXPAND switch set-
ting, plus the difference be-
tween the final setting of the
RANGE-DB switch and its
initial setting in 21 above.
24 Convert db reading to VSWR
VSWR of unit under test is deter-
value using db (reflection coef-
mined from chart
ficient) to VSWR conversion
chart in chapter 2, section III,
of TM 9-4931-294-15/1.
