5.8.3 Current Measurement with Current Clamp Transformer
Alternating Current Measurement and Total Harmonic Distortion,
Direct and Pulsating Current – A AC and thd, A DC, A AC+DC
Current/Current Transformer Output
When a current clamp transformer is connected to the multimeter
( mA/A input) all current displays appear with the correct value in
accordance with the selected transformation ratio. The only prere-
quisite is that the current transformer is equipped with at least one
of the below listed transformation ratios, and that the ratio has
been previously selected in the following menu (Cl ip ≠ 0FF) (see
also section 6.4).
Note
The order of the measuring functions for switch position A
is changed when a clip factor is selected:
The two AC measuring functions, A AC and thd (A AC), are
moved to the beginning, because DC current cannot be
measured with common current clamp transformers.
