POWER SUPPLY Fuses test points for measuring regulated output voltages and voltage adjustment controls are located on the low voltage regulator assembly Access to the assembly is obtained by removing the instrument rear panel Each low voltage supply is fused The fuses are in series with the regulator transistors and all regulated output power fiows through the fuse for the respective supply 8 29 Since the 100 V and 100 V supplies are cur rent fold back limited and the 15 V and 12 6 V supplies are current limited an open fuse generally indicates that trouble exists in the regulator portion of the supply If a fuse is open check the series regulator iransistor driver transistor and comparator 8 80 Troubleshooting the low voltage supply 18 facilitated by removing the power supply from the oscilloscope This will provide access to the power transformer rectifiers and filters Removing the module also disconnects the power supply from all other circuits of the oscilloscope thus confining the troubleshooting effort to the low voltage supply The procedure for removing the power supply module is explained later in this section of the manual WARNING 8 Oo RER Lethal voltages are exposed when the power supply module is operated outside the oscilloscope mainframe 8 31 The 100 V supply should be checked first since all other supplies use it as a reference Un regulated operation of all of th
