105 V adjustment and readjust if necessary.
6. Select the 10 V - 30 V range, set vernier to 1 and check that 10 V setting is
within ± 10 %. With vernier fully CCW the amplitude must be ";;; 1 0 V.
Readjust R457
if necessary.
7. Select 3 V - 10 V range and check that the amplitude is> 10 V with vernier set
to CW o Readjust R462 if necessary.
