10.2 Totalizer and Pulse Output
To use the totalizer and pulse output for external use, proceed as follows.
Count rate and Pulse Width Setting
Set the flow volume per count (pulse) (count rate) and the pulse width. See 8.2.20, “Count
rate, Pulse Width Setting Mode and Pulse Width.”
* The count rate can be set within the range below in reference to the
setting range:
3.6 (pulse/s) to 10800000 pulse/h
(1/1000 pulse/s to 3000 pulse/s) (Note 1)
* The pulse width can be set within the range 0.3ms to 500ms.
However, the pulse width must be set to 40% or less of the period of
output frequency at full scale. (Note 2)
If the pulse width setting mode is AUTO, the pulse width is automatically set. If the pulse width
setting mode is MANUAL, set it after checking the acceptable signal width of the receiving
instruments.
If pulse output is not used, pulse width setting is not needed.
DO setting
Refer to 8.2.18, "Digital Output" to set the Digital Output 1 (DO1) for Pulse output (PLS
OUT
).
If the digital output function is not set (NO USE) though count rate is set, it will be set to
pulse output automatically.
If pulse output is not used, this setting is not needed.
Return to Measurement Mode
Set the operation mode of the system to the measurement mode. Refer to 7.3.1, “Changing the
Mode.”
Clear (reset) the totalizer. (Note 3)
