The VDE 0413 part 7 specification stipulates that
these instructions should contain a diagram showing
the maximum value which the instrument must
indicate in certain conditions. An earth test being
performed on any electrode system would normally be
carried out to a particular specification. Therefore,
even at the instrument's worst accuracy, the reading is
never above the limiting value required by the
particular specification in question.
The curve opposite shows the maximum value which
shall be indicated by the instrument (at its maximum
error) to ensure that the limiting value of the earth
resistance given in the relevant earth electrode test
specification is met.
