Marking *)

CE, EAC, UKCA

*) 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" and chapter "Technology".
