Adjustment
The measuring
probe
has
been adjusted and
checked by the factory.
However, to
match the probe
to
your
oscilloscope,
the following manipulation
is necessary. Connect
the measuring
pin to socket CAL
of the
oscilloscope. A
trimmer can
be
adjusted
through
a
hole
in the
compensation
box
to
obtain optimum
square-
wave response.

following examples.
