b.
Connect the digital voltmeter low lead to chassis
ground and the high (volts) lead to TP460, located on the
bottom side of the Main circuit board.
c.
CHECK— Note the offset voltage reading at TP460
for use in pari: e.
d. Set the A&B INT switch to CH 1.
e. ADJUST—Trig Offset (R309) so that the voltage
reading is the same as that obtained in part c.
