6、ke direct measurements on the human body. Users who connect a LeCroy oscilloscope directly to a person do so at their own risk. Use only indoors. ?3RZHU?5HTXLUHPHQWV The oscilloscope operates from a 115 V (90 to 132 V) or 220 V (180 to 250 V) AC power source at 45 Hz to 66 Hz. RadioFans.CN 收音机爱 好者资料

7、库 ? No voltage selection is required, since the instrument automatically adapts to the line voltage present. )XVHVThe oscilloscopes power supply is protected against short-circuit and overload by means of two “T”-rated fuses of type according to scope model: ? 6.3 A/250 V AC 9344C, 9350C, 9354C, 937

8、0C, 9374C, 9384C Series ? 5 A/250 V AC9304C, 9310C, 9314C Series. The fuses are located above the mains plug. Disconnect the power cord before inspecting or replacing a fuse. Open the fuse box by inserting a small screwdriver under the plastic cover and prying it open. For continued fire protection

9、at all line voltages, replace only with fuses of the specified type and rating (see above). *URXQGThe oscilloscope has been designed to operate from a single-phase power source, with one of the current-carrying conductors (neutral conductor) at ground (earth) potential. Maintain the ground line to a

The oscilloscope is provided with a three-wire electrical cord containing a three- terminal polarized plug for mains voltage and safety ground connection. The plugs ground terminal

11、is connected directly to the frame of the unit. For adequate protection against electrical hazard, this plug must be inserted into a mating outlet containing a safety ground contact. &OHDQLQJ?DQG?0DLQWHQDQFHMaintenance and repairs should be carried out exclusively by a LeCroy technician (see Chapter

12、 1). Cleaning should be limited to the exterior of the instrument only, using a damp, soft cloth. Do not use chemicals or abrasive elements. Under no circumstances should moisture be allowed to penetrate the oscilloscope. To avoid electric shocks, disconnect the instrument from the power supply befo

13、re cleaning. ?&$87,21Risk of electrical shock: No user-serviceable parts inside. Leave repair to qualified personnel. 3RZHU?2QConnect the oscilloscope to the power outlet and switch it on by pressing the power switch located on the rear panel. After the instrument is switched on, auto-calibration is performed and a test of the oscilloscopes ADCs and memories is carried out. The full testing procedure takes approximately 10 seconds, after which time a display will appear on the screen. RadioFans.CN 收音机爱 好者资料库
