Measuring Equipment Oscilloscope Two L P F Measuring Points E E REFO Disc ABEX TCD 784 Mode TEST MODE CONTROL UNIT G2T Xch Ych Oscilloscope Checking Procedure 1 In test mode load the disc and switch the 5V regulator on 2 Using the SEEK UP and SEEK DOWN buttons move the PU unit to the innermost track 3 Press key 5 to close focus the display should read 91 Press key 2 to implement the tracking balance adjust ment the display should now read 81 Press key 5 4 times The display will change returning to 81 on the fourth press 4 As shown in the diagram above monitor the LPF outputs using the oscilloscope and check that the phase differ ence is within 75 Refer to the photographs supplied to determine the phase angle 5 If the phase difference is determined to be greater than 75 try changing the PU unit to see if there is any improvement If after trying this a number of times the grating angle does not become less than 75 then the mechanism should be judged to be at fault Note Because of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may be seen to wobble the phase difference changes as the disc rotates The angle specified above indicates the aver age angle Hint Reloading the disc changes the clamp position and may decrease the wobble FX MG8227ZT UC 5 6 7 8
