Submit a CFR.

3.8.1 Perform a post-work operational test of each tank TLIs to demonstrate that each radar head/sensor is functional (i.e., Digital readout is displayed).

3.8.2 Ensure that there is interface/communication between the TLI sensor and the Machinery Control and Monitoring System (i.e. Digital readout at the TLI is identical to that displayed).
