6 Assistance Product maintenance agreements and other customer assistance agreements are available for Hewlett-Packard products. For any assistance, contact your nearest Hewlett-Packard Sales and Service Oce. Compliance This instrument has been designed and tested in accordance with IEC Publication 348, Safety Requirements for Electronic Measuring Apparatus, and has been supplied in a safe condition. The instruction documentation contains information and warnings which must be followed by the user to ensure safe operation and to maintain the instrument in a safe condition. Safety Notes The following safety notes are used throughout this manual. Familiarize yourself with each of the notes and its meaning before operating this instrument. WARNING CAUTION Warning denotes a hazard. It calls attention to a procedure which, if not correctly performed or adhered to, could result in injury or loss of life. Do not proceed beyond a warning note until the indicated conditions are fully understood and met. Caution denotes a hazard. It calls attention to a procedure that, if not correctly performed or adhered to, would result in damage to or destruction of the instrument. Do not proceed beyond a caution sign until the indicated conditions are fully understood and met. iv

7 General Safety Considerations WARNING These servicing instructions are for use by qualied personnel only. To avoid electrical shock, do not perform any servicing unless you are qualied to do so. The opening of covers or removal of parts is likely to expose dangerous voltages. Disconnect the instrument from all voltage sources while it is being opened. Protective earth ground on this equipment must be maintained to provide protection from electric shock. This is a Safety Class I product (provided with a protective earthing ground incorporated in the power cord). The mains plug shall only be inserted in a socket outlet provided with a protective earth contact. Any interruption of the protective conductor, inside or outside the instrument, is likely to make the instrument dangerous. Intentional interruption is prohibited. The power cord is connected to internal capacitors that may remain live for 5 seconds after disconnecting the plug from its power supply. For continued protection against re hazard, replace line fuse only with same type and rating ([F 5A/250V]). The use of other fuses or material is prohibited. No user serviceable parts are inside this instrument. The cathode-ray tube is dangerous to handle. Refer servicing to qualied personnel. X-rays generated by this instrument are suciently screened. Die in dieswem gerat entstehende rontgenstrahlung ist ausreichend abgeschirmt. Acell. Voltage/Besehl. SPG<20kV CAUTION Before switching on this instrument, make sure that the line voltage selector switch is set to the voltage of the power supply and the correct fuse is installed. For continued protection against re hazard, replace the fuse only with a fuse of the same type and rating. Always use the three-prong ac power cord supplied with this instrument. Failure to ensure adequate earth grounding by not using this cord may cause instrument damage. Equipment damage may result from incorrect usage. Both metric and inch hardware are used in this instrument. Only clean the instrument cabinet using a damp cloth. v
