Defining the autoramp parameters in the memory

Press and hold MODE for more than one second to enter the

autoramp adjustment mode. The ramp function is a dual

slope output. You may adjust the number of steps between

the start and end positions or the end and start positions,

and the amplitudes of the start and end positions.

When the U1401A is in the autoramp adjustment mode, the

secondary display shows the amplitude of the start or end

position. The first digit on the left of the primary display is
