Before each use, inspect the flexible current transducer and its latching

system for any damage for continued safety. Pay particular attention to the

insulation surrounding the flexible measuring head.

The flexible current transducer and its latching system require no special

care. Ensure that no foreign object obstructs the latching mechanism. Clean

the CT-500 with a damp cloth and a mild detergent. Do not use abrasives,

solvents, or alcohol.

If ct-500 does not perform properly, use the following steps to help isolate

the problem:

• Inspect the coupling system for any damage. If a foreign material is

present, the coupling system will not close properly and errors will

result.

• Inspect the cables between the flexible measuring head and CT-500

circuit box. Also inspect between CT-500 circuit box and DM-5 for any

damage.

• Check the power ON LED on the circuit box is ON.

• Verify the transducer setting on DM-5 is correct.
