2.2 Verification Item
This Verification Tool has 2 modes, which can be run separately.
1. Standard Verification (Standard VF)
• This mode verifies the condition of the AXF without difficulty by checking its internal param-
eters. No external instruments are required.
• Some items are run only when FieldMate is in “online (*1)” mode.
2. Enhanced Verification (Enhanced VF) [Optional]
• This mode provides a more reliable verification by performing a detailed overview equivalent
to SERVICE.
• This mode is optional. If only this mode is completed, “Overall Status” is left blank.
• This mode verifies AXF by using external instruments, such as Magnetic Flowmeter Calibra-
tor AM012, Handy Calibrator CA150, and so on.
• Even when FieldMate is in “offline (*2)” mode, this mode can be run; in this case, some set-
tings must be made manually.
There are only 2 possible combinations:
1. Standard VF
2. Standard VF + Enhanced VF
