Why Can't I use the Measurement Function on Data Loaded From Previous DL1540 Digital Oscilloscope Acquisitions?

The measurement function can be used only when data are saved in the ACQ (BIN) format. In addition, when data are saved in this format, all functions including waveform zoom can be used in the same fashion as with the captured data. When P-P data are saved, the waveform can only be displayed; measurement functions and other functions cannot be used.
