Transformer Output, Current/Current
When a current transformer clamp is connected to the mA/A
multimeter input (not METRAHITAM BASE), all current displays ap-
pear with the correct value in accordance with the selected trans-
formation factor. The only prerequisite is that the current trans-
former is equipped with at least one of the below listed transfor-
mation factors, and that the factor has been previously selected in
the following menu
