clip-on ammeter or lines carrying high potentials. The load spotter can be attached
to the universal head of a hot-line stick and slipped over a live conductor. The
range of conductors is from ½ inch to 2 inches.
Two modes of operation are possible; FREE RUN which continuously displays the
instantaneous current value, or HOLD which retains the highest reading obtained if
the instrument is positioned with the display out of view.
