FILTER
(RESPONSE)
Digital filtering, or response times, changes the response to
rapidly-changing RF or leakage levels; see Theory of Operation on
page 47 for more information.

SLOW
—Equivalent to slow response mode on analog meters. SLOW
is the default setting, and is used for most hand-scanning of microwave
ovens. It responds more slowly to rapidly-changing RF or leakage
levels and tends to average the response to peak levels caused by
oven mode stirring devices. This is designed to meet the
CDRH requirement that an instrument respond to a step CW
microwave input to 90% of its steady state reading within a maximum
of three seconds, while still providing maximum smoothing of
RF peaks.
FAST
—Equivalent to fast response mode on analog meters. It is used
to observe rapid variations in RF leakage and to evaluate the effect of
stirrer modulation on leakage.
