    The Auto mode measurements are not affected by the sync and clamping parameters set in Waveform mode for the manual measurements. Measurement In Auto mode, the VM700T lists measurement names on the left-hand side of the display. Each name is followed by the measurement result, and a notation of the Identification measurement’s reference where applicable.
