is called the low frequency compensation. Each time a probe is
used on an other channel or an other oscilloscope, the probe must
be adjusted.
Therefore the probe is equiped with a setscrew, with which the
parallel capacity of the attenuation network can be altered. To
adjust the probe, switch the probe to the x10 and attach the probe
to a 1 kHz square wave signal. Then adjust the probe for a square
front corner on the square wave displayed. See also the following
illustrations.
