4Serve bias as the center

In a noisy environment, it is advantageous to use negative bias to provide a noise margin. It is

recommended NOT to use less than 1V to set the operation frequency.

There are two AVI analog inputs can be used when this parameter is set to 1 and the SW2 on the control board is set to AVI2. At this moment, ACI is for voltage input.

03-13 Analog Input Delay Time (AVI) Unit: 0.01
