As various 1.003 DISP control functions are interdependent, a certain order 1.003 DISP of adjustment is necessary. The procedure is, therefore, 1.003 DISP presented in a sequence which is best suited to this 1.003 DISP order, cross-reference being made to any circuit which 1.003 DISP may affect a particular adjustment. 1.004 DISP Before any adjustment, the instrument must attain its 1.004 DISP normal operating temperature. 1.004 DISP 1.004 DISP Warming-up time under average conditions is 30 min. 1.005 DISP Tolerances given are for the instrument under test and 1.005 DISP do not include test equipment error. 1.005 DISP 1.005 DISP The most accurate display adjustments are make with a 1.005 DISP stable, well-focused low intensity display. 1.005 DISP 1.005 DISP All controls that are mentioned without item numbers are 1.005 DISP located on the outside of the instrument. 1.006 DISP [32] WARNING 1.006 DISP The opening of covers or removal of parts, except those 1.006 DISP to which access can be gained by hand, is likely to 1.006 DISP expose live parts, and also accessible terminals may be 1.006 DISP live. The instrument shall be disconnected from all 1.006 DISP voltage sources before any adjustment, replacement or 1.006 DISP maintenance and repair during which the instrument will 1.006 DISP be opened. 1.007 DISP If afterwards any adjustment, maintenance or repair of 1.007 DISP the opened instrument under voltage is inevitable, it 1.007 DISP shall be carried out only by a qualified person who is 1.007 DISP aware of the hazard involved. Bear in mind that 1.007 DISP capacitors inside the instrument may still be charged 1.007 DISP even if the instrument has been separated from all 1.007 DISP voltage sources. 1.008 HEAD 9.3 ADJUSTING PROCEDURE 1.009 DISP NOTE: Always use an insulated adjustment tool. 1.010 HEAD 5.2 REMOVING THE COVERS 1.011 DISP The instrument is protected by three covers: a front 1.011 DISP protection cover, a top cover and a bottom cover. To 1.011 DISP facilitate the removal of the instrument's covers, first 1.011 DISP put the fromt protection cover in postition. The proceed 1.011 DISP as follows: 1.011 DISP 1.011 DISP Hinge the carrying handle clear of the front protection 1.011 DISP cover. 1.012 DISP Stand the instrument on its protective front cover on a 1.012 DISP flat surface. 1.012 DISP 1.012 DISP Unscrew the two screws present in the left foot and the 1.012 DISP two screws in the right foot at the rear panel and 1.012 DISP remove these feet. 1.013 DISP The top cover and the bottom cover (without carrying 1.013 DISP handle) can be removed by shifting them backwards and 1.013 DISP lifting them free of the instrument. 1.014 DISP Connect the UUT to the line power and switch it on. 1.015 HEAD 9.3.2 POWER SUPPLY ADJUSTMENTS 1.016 PIC 3320A20 (10,20,R/W) "Connect the 8842A Input Hi to" 1.016 PIC (11,20,R/W) "X4609 and Input Lo to X4611." 1.017 PIC 3320A20 (6,3,R/W) "Note the location of R4607" 1.018 MESS Adjust R4607 for an 8842A reading of 10.0+/-0.1V. 1.019 8842 10V S 2W 1.020 MESS 1.021 PIC 3320A33 (7,48,R/W) "Connect the 8842A Input Hi to" 1.021 PIC (8,48,R/W) "X2517 and Input Lo to X2518." 1.022 PIC 3320A33 (5,44,R/W) "<- Note the location of R462" 1.023 MESS Adjust R462 for an 8842A reading of 5V +/-0.1V. 1.024 8842 5V S 2W 1.025 MESS 1.026 DISP Disconnect the 8842A from the UUT. 1.027 HEAD 9.3.3 CRT ADJUSTMENTS 1.028 PIC 3320A1 (6,16,R/W) " NOTE " 1.028 PIC (7,16,BL/W) "In the case that your instrument " 1.028 PIC (8,16,BL/W) "is completely misadjusted or after" 1.028 PIC (9,16,BL/W) "exchange of A1 it is recommended " 1.028 PIC (10,16,BL/W) "to turn R2658, R2659, R2678 and " 1.028 PIC (11,16,BL/W) "and R2682 completey CCW.
