CHECKING

1)  Terminal wiring:  Check that all cables are correctly con-

nected according to the connection diagram.

2)  Power input voltage:  Check voltage across the terminal 

7 – 8 with a multimeter.

5)  Input:  Check that the input voltage is within 0 – 100% of 

full-scale.

6)  Output:    Check  that  the  load  resistance  meets  the  de-

scribed specifications.
