Maintenance
This chapter covers the cleaning, inspection, troubleshooting, and replacement parts.
Troubleshooting
For corrections requiring repair or replacement of components, refer to the appro-
priate section for your specific model.
Cleaning
Outside Surface It is necessary to keep the following areas clean:
s The outside surface of the wattmeter
s Radiator fins
s Connector
Excessive dust and lint on the cooling fins will interfere with the efficient dissipation
of heat. Periodically wipe, with a soft cloth, the accumulated dust and lint off of the
radiator fins. If the teflon insulator or metallic contact surfaces of the connector
should become dirty, wipe off with a soft cloth. Use a contact cleaner that is
self-drying and does not leave a residue on the inaccessible internal parts.

housing. Clamping bands not tight. Tighten slightly with a
screwdriver.
