Appendix 1 How to Make Accurate Measurements
Because this instrument measures high frequencies, the effects of i
C
s cannot be ignored.
If you connect the current input terminal of this instrument to the side of the power supply (SOURCE)
that is close to its earth potential, the current measurement circuit of this instrument positive and
negative terminals are close to the earth potential, so V
C
s becomes approximately zero and very little
i
C
s flows. This reduces the effect on measurement accuracy.
