(1) The over-range flag will come on when the normal operating range is exceeded. The module will continue to

convert the analog output up to the maximum full scale range. The flag automatically resets when within the
normal operating range.

(2) Includes offset, gain, drift, non-linearity and repeatability error terms.
(3) Output ripple is the amount a fixed output varies with time, assuming a constant load and temperature.
(4) Repeatability is the ability of the output module to reproduce output readings when the same controller value is

applied to it consecutively, under the same conditions and in the same direction.
