indicate the relative location of the peak reading on the
digital display. The Bar Graph display responds very
rapidly and will show stirrer/turntable modulation as well
as minima and maxima of leakage around the microwave
oven periphery. Because of the fast, unfiltered, response
of the Bar Graph display, the digital peak reading may lag
behind the Bar Graph indication depending on the filter
factor chosen. When the instantaneous RF indication on
the Bar Graph display is greater than the reading on the
digital display, the Bar Graph segment proportional to the
digital reading is dark. In this way the Peak Hold mode of
the meter can be used to observe the effects of the
various digital filters on fast changing RF inputs.

Two end segments are always lit to define
the scale.
