Backdating Changes8-2 This section contains backdating informationwhich adapts this manual to instruments with serialnumbers lower than that shown on the title page.8-3 CHANGE SEQUENCE8-4 Changes are listed in the serial number orderthat they occurred in the manufacture of the instrument.However, in adapting this manual to an instrument witha particular serial number, apply the changes in reverseorder. That is, begin with the latest change and progressto the earliest change that applies to the serial numberin question. Table 8-1 lists the serial numbers to whicheach change applies.NOTE: This manual applies to serial number 1604G00461and onwards. For instruments with very early serialnumbers e.g. 1604G00103, an alternative method toincorporating all the changes from this backdating sectionin the schematics/component layouts at the end of thismanual, would be to use the schematics/component-;layouts in the preliminary manual for purposes of docu-mentation. In this way, a clearer overview of the "add"and "delete" instructions in this section can be achieved.InstrumentSerial Number1604G001021604G001031604GOO104 to -1081604G001091604GOOll01604G00111 and -1121604G001131604G001141604G001151604GOOl16 to -1181604G001191604G001201604G00121 to -1231604G00124 and -1251604G001261604G001271604G001281604G001291604G00130 and -1311604G001321604G00133 to -1351604G00136 and -1371604G00138 to -1401604GOO141 to -2241604G00225to -2281604G002291604G00230 to -2901604G00291 to -3201604G00321 to -34016Q4G00341 to -3901604G00391 to -460Make ManualChanges4 to 101 to 3; 5 to 104 to 101 to 101t03;5to101 to 105 to 101 to 104 to 101 to 104 to 101 to 102 to 104 to 105 to 103 to 104 to 103 to 104 to 103 to 104 to 101 to 3; 5 to 104 to 105 to 106 to 105 to 106 to 107 to 108 to 109 and 1010CHANGE 1Change A3 Parts List to read:VR1CHANGE 2010 BKON 6.19 V 1902-0551On Board A2 Parts List, make the following changes:deletechangechangeadddeleteC29C11 toC27 toC28R18, R19C-F 1500 pFC-F 40f.J.FC-F .1 J.1.FC-F 40 J.1.FR-F 1 K0160--oS970180-00S00180-02690180-00500757--0280CHANGE 3Delete the following components from the Main Frame Parts List:Cl, C2, C3 C-F 330 pFChange the A2 Parts List to read:R26 R-VAR 5 KR27 R-F 5.62 KR28 R-F 20 KDelete VR32 DIO-ZNR 23.7 VAdd C23 C-F 3.3 J.1.FCHANGE 4Add the following components to the A1 Parts List:0160-22082100-32520757-02000757--04491902-32560180-2141from the A2 Parts List.to the A3 Parts List.CR43VR44VR45VR46010 PWR 1 KV010 BKON 100 V010 BKON 100 V010 BKDN 100 V1901--07321902-01751902-01751902-0175Change A1 Parts List to read:Q41CHANGESXSTR NPN 1854-0665Delete the following components from the A1 Parts List:CR2 010 PWR RECTCR4 010 PWR RECTCR5 010 PWR RECT1901-10871901-10871901-1087I(lChange the A1 Parts List to read:CRlCHANGE 6DIO FW BRDG 600 V 1901-0367Change the Main Frame Parts List to read:F1F1F1CHANGE 72110-04652110-04672110-0470CAP-FUSEHOLDERNUT HEXFUSEHOLDER BODYChange Frame Parts List to read:MP11XF1CHANGESANGEL FUSEFUSEHOLDER B08080-005022110-0564Delete MP2 KEEPER CAP 08080-42301 from A1 Parts List.CHANGE 9Change A2 Parts List to read:R32CHANGE 10R-F14.7K 0698-3156Change Frame Parts List to read:Sl 3101-1720 SW PBTN DPDT
