Main Power and Test Input Dis- connect: Unplug instrument from wall outlet, remove power cord, and remove all probes from all terminals before servicing. Only qualified, service-trained person- nel should remove the cover from the instrument.

If your product is provided with a ground- ing-type power plug, the instrument chassis and cover must be connected to an electri- cal ground to minimize shock hazard. The ground pin must be firmly connected to an electrical ground (safety ground) terminal at the power outlet. Any interruption of the protective (grounding) conductor or discon- nection of the protective earth terminal will cause a potential shock hazard that could result in personal injury.

Cleaning

Clean the outside of the instrument with a soft, lint-free, slightly dampened cloth. Do not use detergent or chemical solvents.
