Marking
*) Real applicable approvals/markings see type plate on the side (product marking).
*) In AC mode, the terminal operates in TrueRMS mode, i.e. it does not digitally record the peak values Vpp,
which are approx. 1.4 times larger, but the RMS value, see "Measuring procedure [} 21]" and chapter
"Technology [} 20]".
