OPERATING INSTRUCTION-25 MAINTENANCE Safety First 1-2-1 General Serving Precautions (1) a. Always unplug the instruments AC power cord from the AC power source before (1) removing or

4、reinstalling any component, circuit board, module or any other instrument assembly. (2) disconnecting any instrument electrical plug or other electrical connection. (3) connecting a test substitute in parallel with an electrolytic capacitor in the instrument. b. Do not defeat any plug/socket B+ volt

5、age interlocks with which instruments covered by this service manual might be equipped. c. Do not apply AC power to this instrument and/or any of its electrical assemblies unless all solid-state device heat sinks are correctly installed. d. Always connect a test instruments ground lead to the instru

6、ment chassis ground before connecting the test instrument positive lead. Always remove the test instrument ground lead last. Note: Refer to the Safety Precautions section ground lead last. (2) The service precautions are indicated or printed on the cabinet, chassis or components. When servicing, fol

7、low the printed or indicated service precautions and service materials. 2 (3) The components used in the unit have a specified flame resistance and dielectric strength. When replacing components, use components which have the same ratings, by () or by () in the circuit diagram are important for safe

8、ty or for the characteristics of the unit. Always replace them with the exact replacement components. (4) An insulation tube or tape is sometimes used and some components are raised above the printed wiring board for safety. The internal wiring is sometimes clamped to prevent contact with heating co

9、mponents. Install such elements as they were. (5) After servicing, always check that the removed screws, components, and wiring have been installed correctly and that the portion around the serviced part has not been damaged and so on. Further, check the insulation between the blades of the attachme

10、nt plus and accessible conductive parts. 1-2-2 Insulation Checking Procedure Disconnect the attachment plug from the AC outlet and turn the power ON. Connect the insulation resistance meter (500V) to the blades of the attachment plug. The insulation resistance between each blade of the attachment pl

11、ug and accessible conductive parts (see note) should be more than 1 Megohm. Note: Accessible conductive parts include metal panels, input terminals, earphone jacks, etc. 1-3 ESD Precautions Electrostatically Sensitive Devices (ESD) Some semiconductor (solid static electricity) devices can be damaged

12、 easily by static electricity. Such compo9nents commonly are called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integrated circuits and some field-effect transistors and semiconductor chip components. The following techniques of component damage caused by static el

13、ectricity. (1) immediately before handling any semiconductor components or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be remove

14、d for potential shock reasons prior to applying power to the unit under test. (2) after removing an electrical assembly equipped with ESD devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly. (3) Use only a gro

15、unded-tip soldering iron to solder or unsolder ESD device. (4) Use only an anti-static solder removal devices. Some solder removal devices not classified as “anti-static” can generate electrical charges sufficient to damage ESD devices. (5) Do not use freon-propelled chemicals. These can generate el

16、ectrical charges sufficient to damage ESD devices. (6) Do not remove a replacement ESD device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comp

17、arable conductive materials). (7) Immediately before removing the protective materials from the leads of a replacement ES device touch the protective material to the chassis or circuit assembly into which the device will be installed. CAUTION: Be sure no power is applied to the chassis or circuit, a

18、nd observe all other safety precautions. (8) Minimize bodily motions when handling unpackaged replacement ESD devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damag

19、e an ESD device). 3 2.
