5.7.5 Alternating Current Measurement with Current Clamp Transformer,
A AC and Hz
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
prerequisite 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).
