Safety Summary

Specific Precautions Observe all the following precautions to ensure your personal safety and to prevent damage to either the oscilloscope or equipment connected to it.

Power Source

The oscilloscope operates from a power source that will not apply more than 250 VRMS between the supply conductors or between either supply conductor and ground. A protective ground connection, through the grounding conductor in the power cord, is essential for safe system operation.

Grounding the Oscilloscope

The oscilloscope is grounded through the power cord. To avoid electric shock, plug the power cord into a properly wired receptacle with an earth ground connection. Do this before making connections to the input or output terminals of the oscilloscope.

Without the protective ground connection, all parts of the oscilloscope are potential shock hazards. This includes knobs and controls that may appear to be insulators.

Use the Proper Power Cord

Use only the power cord and connector specified for your product. Use only a power cord that is in good condition.

Use the Proper Fuse

To avoid fire hazard, use only a fuse that meets all type, voltage, and current specifications on page 2-1.

Do Not Remove Covers or Panels

To avoid personal injury, do not operate the oscilloscope without the panels or covers.

Do Not Operate in Explosive Atmospheres

The oscilloscope provides no explosion protection from static discharges or arcing components. Do not operate the oscilloscope in an atmosphere of explosive gasses.

Electric Overload

Never apply a voltage to a connector on the oscilloscope that is outside the range specified for that connector.

Service Safety Summary

Only qualified personnel should perform service procedures. This safety information applies to all service personnel.

Do Not Perform Service While Alone

Do not perform internal service or adjustment of this product unless another person capable of rendering first aid and resuscitation is present.

Use Care When Servicing With Power On

Dangerous voltages exist at several points in this product. To avoid personal injury, do not touch exposed connections or components while power is on. Disconnect power before removing protective panels, soldering, or replacing components.

Disconnect Power

To avoid electric shock, disconnect the main power by means of the power cord or, if provided, the power switch.

Use Caution When Servicing the CRT

To avoid electric shock or injury, use extreme caution when handling the CRT. Only qualified personnel familiar with CRT servicing procedures and precau& tions should remove or install the CRT.

CRTs retain hazardous voltages for long periods of time after power is turned off. Before attempting any servicing, discharge the CRT by shorting the anode to chassis ground. When discharging the CRT, connect the discharge path to ground and then the anode. Rough handling may cause the CRT to implode. Do not nick or scratch the glass or subject it to undue pressure when remov& ing or installing it. When handling the CRT, wear safety goggles and heavy gloves for protection.

X*Radiation

To avoid x&radiation exposure, do not modify or otherwise alter the high&volt& age circuitry or the CRT enclosure. X&ray emissions generated within this product have been sufficiently shielded.
