Signal inversion

If the positive and negative lead wires were merely swapped, then the signal will just be inverted (not otherwise distorted). The signal may be flipped over either with “Transform > Rescale…”:

Transform > Rescale to invert data

or “Transform > Waveform Math…”:

Transform > Waveform Math to invert data

In the case of “Rescale”, just select the inverted channel before choosing “Rescale”. In the case of “Waveform Math”, the source channel is specified through the dialog box, so it is not necessary to select the channel first.
