2.2 Verication Item

This Verication Tool has 2 modes, which can be run separately.

1. Standard Verication (Standard VF)

• This mode veries the condition of the AXF without difculty 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 Verication (Enhanced VF) [Optional]

• This mode provides a more reliable verication 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 veries AXF by using external instruments, such as Magnetic Flowmeter Calibra-

tor AM012, Handy Calibrator CA150, and so on.

• Even when FieldMate is in “ofine (*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
