NOTE:
The open circuit correction is quite sensitive to noise - both
noise originating externally and induced noise. Therefore, if
open circuit correction fails, you should check the following
points before starting the correction process again:
Check that the test fixture or the test cables are properly
connected.
Check that nothing is connected to the test fixture or the
test cables.(Open circuit correction cannot be performed
while any test piece is connected to the test fixture or the
test cables.)
Check the test leads are arranged as closely as possible
to their configuration in which measurement wii be
performed.
During the correction process, be sure not to disturb the
fixture and the test cables or to move your hand near
them.
