(6) About dummy output feature (special functions)
NOTE: This feature is valid only for "factored pulse" output. (Dummy output is not available for unfactored
pulses.)
By the following steps, a 1Hz or 10Hz simulated factored pulse train can be furnished irrespective of
flowmeter measurement.
•
1Hz simulated output mode (dummy output 1 mode Symbol: Pd1)
①
According to the "Menu Trees and Switch Operation" (page 57, show dummy output 1 ("Pd1 1" on the
LCD).
②
Hold MODE button depressed for 2 second to go to the dummy output run mode. (The display shows
"Pd1 0."
③
Operation within the dummy outut run mode
•
Press RESET button
→
Dummy output appears and the counter counts in sync with the pulse output
produced.
•
Press MODE button
→
Dummy output stops.
•
Hold MODE button depressed for 2 seconds
→
Dummy output run mode is terminated, returning to the state
①
.
NOTES
：
1. The procedure above applies to 10Hz simulated output mode (dummy output 2 mode Symbol:
Pd2).
2. The pulse train appears with pulse width setting Pon.
