Page 10: Functions And Operation
6 Functions and Operation Apart from the standard continuous operation, the CV-M77 features three external triggering modes, Edge Pre-select, Pulse Width Control mode and Readout Delay mode. These 3 external triggering modes operate with H non-reset. In H non-reset, the exposure will be synchronized to the internal HD and the exposure will start at the first HD after the negative going edge of the trigger (see figure 6-1). -
