3-4-6. Stair Case Signal Adjustment Procedure

Adjust the stair case signal to display signals in the sequential mode on the waveform monitor. Make this
adjustment when signals in the sequential mode are not displayed correctly on the waveform monitor.
When the waveform monitor is connected to the unit, adjust the stair case signal with potentiometers
RV2601 and RV2602 on the DPR-300 board.
1. Press the SEQ button of the WAVEFORM MONITOR button or MONITOR SELECT button of
RCP-750/751, etc.
2. Adjust the position of the signal to be displayed with potentiometer RV2601 on the DPR-300 board.
3. Adjust intervals A and B (shown in the fi gure below) of the signal to be displayed with potentiometer
RV2602 on the DPR-300 board, so that A and B are nearly equal.
When the SEQ button of the WAVEFORM MONITOR button or MONITOR SELECT button of
RCP-750/751, etc. is pressed, the waveform monitor control signal of the unit is output in synchronization
with the WF connector output signal.
