Specifications
Input Accuracy:
Refer to Table 2
Output Accuracy: 4.8µA
(0.03% of 4-20mA span)
Overall Accuracy: overall
accuracy of the unit is the
combined input and output
accuracy. It includes the
combined effects of linearity,
hysteresis, repeatability
and adjustment resolution.
It does not include ambient
temperature effect. For T/C
input only, add the Reference
