Turn off the power to the Analyzer/Controller. More than one switch may be required to remove the power.

With the power off open the case:

Grasp the bottom center portion of the front bezel and pull it downward and toward you slightly to disengage the bottom of the bezel from the edge of the case.

Lift the bezel gently to disengage it from the top edge of the case.

Swing the bezel to the left. (The bezel and display assembly is mounted on pivot arms.) The safety cover with its warning label will be visible.

With the power off remove the safety cover by removing the single screw holding it in place.

Label and remove the field wiring connected to the analog output terminals.

Feed the test wiring through the conduit hole in the case and connect the appropriate type of meter to each of the analog output terminals to be tested. Be sure to observe correct polarity.

Close the case and power up the unit. Do not connect power until the case is closed.
