Model 2750 Multimeter/Switch System User’s Manual Limits and Digital I/O 9-11
Setting digital output
The OUTPUT menu (shown in Table 9-1) is used to control and configure digital outputs.
Menu items for the digital output include:
• DOUTPUT — Use to enable (ON) or disable (OFF) the digital outputs.
• PULSE — Use to enable (YES) or disable (NO) the pulse option for the digital
outputs.
NOTE The factory default pulse time is 2ms maximum. Using remote programming,
pulse time can be set from 0.001 to 99999.999 sec. It cannot be set from the front
panel.
• LSENSE — Use to select the logic sense; active HIGH or active LOW. With active
high selected, an output will be at approximately +5V when a reading is at or
exceeds the limit. Conversely, with active low selected, an output will be at 0V
when a reading reaches or exceeds the limit.
• MASTR LATCH — Use to enable (Y) or disable (N) the master limit latch. When
enabled, the master limit remains latched when a reading limit is reached or
exceeded. When disabled, the master limit line releases immediately when the
reading is inside all four limits.
