Input Accuracy:
See Tables 2-7
Output Accuracy:
±0.015%
of span
Overall Accuracy:
The
overall accuracy of the unit
is the combined input and
output accuracies. It includes
the combined effects
of linearity, hysteresis,
repeatability and adjustment
resolution. Does not include
ambient temperature effect.
