Analog Conversion Relationship Introduction
The external analog has three channels, and the parameter configuration for
each channel follows a linear function y=kx+b. The parameter explanations are
as follows:

Independent variable x: The actual input voltage value of the external
analog channel.

Slew factor k: Same as Mx in the menu, set by the user.

Offset b: Same as Mb in the menu, set by the user.

y: The actual output value of the instrument. (Voltage when CV is prioritized,
current when CC is prioritized)
Name Description
corresponds to Volt Low/Curr Limit- in the menu.

CV priority: Specify the value of the current lower
limit I-.

CC priority: Specify the value of the voltage lower
limit Vl.
External analog function.(External analog interface is optional.)
