6. On Channel A’s Logic tab, enter: inA = outB and outC; (You’ll learn more about channel
logic in the Logic section above).
7. On Channel A’s Counter tab, select milliseconds as the units.
8. Click Disable, then click Apply.
9. Lastly, go “on line” and click Send Logic on the Main screen to update the new logic for all
channels.
10. On Channel A’s properties screen click Enable.
The time difference measurements should now appear, in rapid succession, in the Last Measured
Period box on Channel A.
NOTE: The Model 725 may be measuring time differences faster than it can display
them all on the monitor.
Now, check Hold measurement. Note that the displayed measurement does not change. Uncheck
Hold Measurement, then re-check Hold measurement again to freeze another measurement.
Dynamically-Delayed Pulse Mode
The dynamic delay first measures the time difference between two pulses, like a timer. Next, it
scales that difference by a user-defined factor. It subtracts an offset value, waits the duration of
the dynamically calculated delay, then sends a pulse to the channel output.
NOTE: The dynamic delay is particularly useful for ballistics or gas dynamics
experiments, in which the velocity of a projectile or wave must be calculated and used to
time the triggering of an experimental device.
Dynamically Delayed Pulse mode includes several properties tabs.
