communicating with meter but all

 

Ω)

chords display failures

Verify that the resistance of transducers is within Specification (1-2 .

Check the Acquisition board (see Appendix E).

 

 

Check the interconnect cables between the base assembly and the head assembly

 

 

(see Appendix E).

 

 

 

chord is not indicating

Check the resistance of the failed transducer.

 

If Chord A is not indicating, change the transducer cables from Chord D to chord A.

 

 

If Chord D then fails, the transducers are bad on Chord A (see Appendix E).

 

The same test procedure can be accomplished by swapping Chords B and C if a

 

 

chord fails in either chord (see Appendix E).

 

 

Note that the outside chord cables cannot be exchanged with inner

 

 

chord cables.
