Normal maintenance for the Model 8009 consists of periodic cleaning of the

and scratched. Also included in this section is a procedure to check out the

operation of a test system, and a parts list.

The electrodes of the Model 8009 should be periodically cleaned with methanol

or other suitable solvent. The connectors should also be kept clean to prevent

scratched.
