Model 2700 Multimeter/Switch System User’s Manual Limits and Digital I/O 9-11
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.
Perform the following steps to enable and configure digital outputs:
1. Press SHIFT and then OUTPUT.
2. If the digital output is already on (DOUTPUT: ON), proceed to step 3. Otherwise,
press
to move the cursor to the right, press Δ or ∇ key to display “ON,” and
press ENTER.
3. Use the ∇ key to display the master limit latch (MASTR LATCH) setting: N (no)
or Y
(yes).
4. If you want to retain the present master limit setting, proceed to step 5. Otherwise,
press
to move the cursor to the right, press Δ or ∇ key to display “Y” or “N,”
and press ENTER.
5. Use the ∇ key to display the present logic sense (LSENSE) setting: HIGH or
LOW.
6. If you want to retain the present logic sense setting, proceed to step 7. Otherwise,
press
to move the cursor to the right, press Δ or ∇ key to display “HIGH” or
“LOW,” and press ENTER.
7. Use the ∇ key to display the present PULSE mode setting: NO or YES.
