When the override potentiometer is turned to the right, the control outputs an analogue voltage which is

increased proportionally to the servo lag up to a maximum value of 10V. The control operates correctly,

if a voltage of 10V ± 0.1V can be measured at the test adapter with the multimeter. If no voltage can be

measured, the analogue output of the logic unit is probably defective.
