The following accuracy table is valid for calibration under the following conditions:
•
Ambient temperature 23 °C ± 5 °C
• No nodes share power with the FieldDAQ device under calibration
The test limits listed in Table 3 are derived using the values in the following table.
Table 7. FD-11603 Voltage Accuracy Under Calibration Conditions
Percent of Reading (Gain Error) Percent of Range (Offset)
±0.037% ±1.05 mV
Note Values in this table are intended for calibration verification only. These
values only apply under the specific calibration conditions described in this
document, and are not to be construed as general operational specifications of the
FD-11603. For operational specifications, refer to the most recent
