A/D Calibration
Because the PCL-813 supports a variety of A/D
input ranges, accurate calibration for a cer-
tain A/D range may result in a small offset
when the input range is altered. It is strongly
suggested that you recalibrate whenever a dif-
ferent A/D range is selected.

(1)
Short the A/D input of Channel 0 to
AGND. Adjust VR1 until the reading of the A/D
conversion flickers between 2047 and 2048.
(2)
Apply a voltage with a full-scale value
corresponding to the specific A/D input range
to A/D Channel 0. Adjust VR2 until the reading
of the A/D conversion flickers between 4094 and
4095.
