Power Requirements
The oscilloscope requires a power source of either 115 or 230 volts ac, —25%
to +15%; single phase, 48 to 66 Hz; 320 VA maximum .
Power Cord
This oscilloscope is a Safety Class 1 instrument with an exposed chassis that
is directly connected to earth through the power cord that meets IEC
Standard 348. The oscilloscope is provided with a three-wire power cord.
When connected to an appropriate ac power outlet, the cord grounds the
instrument cabinet. The type of power-cord plug shipped depends on the
country of destination.
The Service Guide for a listing of the power cords that are available for the
oscilloscope.
SHOCK HAZARD! Before connecting the oscilloscope to the power line or
connecting to circuits that are connected to the power line, make sure the
protective earth terminal of the oscilloscope is connected to the protective
conductor of the power cord. Failure to do so could result in electrical
shock.
Also, make sure you insert the power plug into an outlet that contains a
protective earth contact. Do not use an extension cord without a protective
earth conductor (grounding). The grounding of one conductor on a
two-conductor outlet is not sufficient for grounding purposes to prevent the
possibility of electrical shock.
