This function can inspect each condition of the magnetic circuit, excitation circuit, and calculation
circuit, and executes the device health diagnosis of the product based on their internal alarm
record along with their wiring misconnection. This function evaluates the diagnosis result based
on the conditions of the product and shows "Passed" if no problem is found or "Failed" if a
problem is found on the display.
The following execution results are shown on the display.
• Examples of "Passed" results
VF check results
VF Operation time
Magnetic circuit result
Exciting circuit result
Calculation circuit result
Device status result

Contact Yokogawa service center if the "Failed" message is displayed for items from "Magnetic
circuit result" to "Device status result".
If "Failed" is displayed for "Connection status result", check for wiring misconnection between the
sensor and transmitter (refer to Subsection 5.9.5 for detail) and damage on the cables.
The verification function can be used in two ways depending on the state of the fluid; one state
where a fluid is flowing and another state where no fluid is flowing.
The two diagnosis results (current and previous) are stored in the device memory, and they can
be checked later.
If the verification function is used, the following results can be displayed.
Total judgment result
