6.2.1 “Circuit” check and “Device Status” check

(Verication Tool is in “online” mode)

CAUTION

• “Circuit” check and “Device Status” check temporarily change the parameters of AXF. In

case of unexpected termination, follow 8.2.

• The AXF owtube should be completely lled with uid, otherwise the results may be

inadequate.

• These items are run only when Verication Tool is in “online” mode.

• These items are veried for 2 types. Each condition check can be run separately.

(A) “No Flow” condition:

Veries the condition of the AXF by checking;

- Circuits including the excitation circuit and the magnetic circuit inside the owtube when

the uid velocity is completely zero.

- The present and past history of alarms.

(B) “Flow” condition:

Veries the condition of the AXF by checking;

- Circuits including the excitation circuit and the operation circuit which calculates the ow

velocity when the uid velocity is sufcient.

- The present and past history of alarms.

• There are 3 combinations:

(1) No Flow

(2) Flow

(3) Flow + No Flow

• The check items of the “Circuit” check depend on the case as follows:

• Nominal size of the unit.

• With or without the optional code ELC (DC Noise Cut Circuit).

• Test condition type; “Flow” or “No Flow”.

For details, see Table 6.2.2.
