Delta mode should be used with continuous rotation potentiometers. It effectively
filters out the dead zones and provides for smooth, uninterrupted readings.
Inputs are controlled as Channels 1 through 8.

Sample Application

This is an example of Axcess programming that is required before using an AXP-AI8.
Example 1:
PROGRAM_NAME='AI8_EX rev 1'
(* DATE:06/18/02 TIME:17:32:26 *)
(* Date: 12/18/2001 Time: 11:50:50 AM AXedit user: JSHMOE *)
(*{{PS_SOURCE_INFO(PROGRAM STATS) *)
(** FIRST, the program under studio can be written many ways
(** but we have to stay within the boundaries of the compiler and
(** use of KEYWORDS. This file was created for an AXCESS system
(** master and when compiling in AXCESSX, the word BUTTON is NOT a KEYWORD **)
