Click "OK" to execute the checks. Once they are finished, a message box (Fig. 115) will be displayed.
Click the "OK" button to complete the dynamic device installation state check.
The results are displayed as shown in Fig. 116.
Diagnosis results are as follows (phase difference received from the DSP is monitored for 30 seconds,
and the difference between the maximum and minimum values is examined):
・
"Stable flow": 1000 or less.
・
"Not so stable flow": More than 1000 and equal to or less than 2000.
・
"Unstable flow": More than 2000, or "P.O. Signal Alarm, Drive Input Out of Range" occurred.

Click the "OK" button to return to the window from before the check, and then click the "Cancel" button
to close the window.
Clicking "OK" here will start the dynamic device installation state check over again.
3.7.2 Loop test (Loop test)
Simulated output is created.
3.7.2.1 Analog output 1 loop test (Fix Analog 1)
This test can be used to put analog output into a simulated output state, and to verify the output line with
a loop test.
Since this creates simulated output regardless of the process state, if the flowmeter
’
s output is used to
control valves or other such parts, then for the sake of safety, change the control loop to manual control
so that the control loop is in a state whereby it is not influenced by the flowmeter
’
s output.

Click the "Diag/Service (T)" menu, and then select and click "Fix Analog 1" from the "Loop Test" drop-
down list.
