8. Wait for
the
Power Meter's digital readout
to
stabilize and verify
that
the

NOTE
The dB (REL) specifications
are
for within-range measurements.
For
range-to-range accuracy, add the uncertainty associated with
the range in which the reference
was
entered,
to
the uncertainty
associated with
the
range in which the measurement
was
made.
For example,
if

the total uncertainty

DESCRIPTION:
After

cal'ibrated
on the 1

is
monitored as the Range Calibrator
is
