IMPORTANT: For DC, the values are based on a good quality digital
volt-ohmmeter (DVM) or equivalent reading average (not RM5)
values. ForAC, the values are RMS readings. The DC voltages
shown are with respect to DC circuit common lead 71 (pin B ofplug
PLG5 I) unless otherwise indicated. The tolerances are ± 10% unless
otherwise specified.
