3.13 OPERATOR MAINTENANCE
No scheduled maintenance is required, other than to keep the high current connections tight
and to ensure all airways are clear of obstructions that could cause the load to overheat during
operation at higher power. Calibration Verification should be performed yearly or as required.
The exterior of the load should be cleaned periodically, as is necessary, using a soft cloth damp-
ened with a mild, non-abrasive, water-soluble detergent, and then rinsed with a water-damp-
ened soft cloth.
