8.6 Dummy Pulse Output
Thanks to the dummy pulse output feature, the monitor can provide a 0Hz simulated pulse output irrespective of
actual flowmeter operation. And it counts the number of pulses so produced on the total counter. With this feature,
you can easily run a connection and performance check between this monitor and other systems coupled.
Given below is the procedure to use this output. ("X" and "Y" represent numerical values of setting.)
CAUTION:
When this feature is enabled, the monitor produces a train of dummy pulses
irrespective of actual flowrate. In applications where the flowmeter output is
used as control data, this operation should be avoided, however. Incidentally,
dummy pulse accuracy is ±1 count with respect to the indicated reading.
(1) Select Dummy pulse output.
Description
Show the flowrate window.
Hold the "MODE" button depressed for sec. to show the alarm menu.
Press the "RESET" button once to show the basic data menu.
Press the "MODE" button times to show the dummy pulse output.
(2) Run dummy pulse output.
Description
Dummy pulse output window
Hold the "MODE" button depressed for sec. to bring up the dummy pulse out-
put standby mode.
[The display reads as shown at left. At this point, pulse output is not activated.]
Upon depression of the "RESET" button, a 0Hz flowrate pulse output appears.
(To stop dummy pulse output, take step (3) to terminate dummy pulse output.)
["XXXX" in the diagram increases by one count with each pulse generation.]
To stop dummy pulse output, press the "MODE" button.
["YYYY" in the diagram shows the number of pulses produced as dummy pulses.]
(To reopen dummy pulse output, press the "RESET" button. To stop dummy
pulse output, take step (3) to terminate dummy pulse output.)
(3) Terminate the dummy pulse output
Description
Dummy pulse output stopped.
Hold the "MODE" button depressed at least for more than sec. to show the
dummy pulse output.
Press the "MODE" button times to show the basic data menu.
Hold the "MODE" button depressed at least for more than sec. to shown the
