Appendix 1 How to Make Accurate Measurements
Because the WT300 series measures high frequencies, the effects of i
C
s cannot be ignored.
If you connect the WT300 series current input terminal to the side of the power supply (SOURCE) that
is close to its earth potential, the WT300 series current measurement circuit 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.
