3.7.1.2 Fix Pulse (pulse output loop test)
This test can be used to put pulse output into a simulated output state, and to verify the output line with a
loop test.
The test creates simulated output regardless of the process state. If the flowmeter's output is used to
control valves or other such parts, change the control loop to manual control for the sake of safety, and
so that the control loop cannot be influenced by the flowmeter's output.
(1) Click "Diag/Service (T)" from the menu, and then click on "Fix Pulse" from the drop-down list of "Loop
Test".
(2) The following window (Fig. 3-53) will be displayed. Select the simulated output value and click "Start"
button. To set and output a desired output value, select "Other" and enter the pulse frequency to be
output, then click "Start" button.
The available range of pulse frequency is 1 to 11000Hz. By clicking "Cancel" button, "Fix Pulse" is
exited.

(3) By clicking "Start" button, the message box (Fig. 3-54) will be displayed. By clicking "OK" button,
"Fix Pulse" will be started.
By clicking "Cancel" button, the window will return to the window shown in Fig. 3-53.
NOTE: Note that the cumulative total of flowmeter is also counted when the simulated output is
created.
