When
usiag other
than a 600
O
load, a correction
must be
applied, to obtain
true db
values. The
chart below indicates some typically
used
loads, and the
cor'
rection
which must
be applied. A
generalized
equation
for finding
the correction
is:
db correction
=
10 los'o 600
R
Where R
is the load in ohms. If R is
greater
than
600
ohms,
the factor
becomes
negative,
and must be subtracted from the db reading.
If R is less than
600 obmg,
the
correction is added to the db reading.
