Overview
look for problems with the module or the wiring. With FieldPoint
The National Instruments [c]FP-AI-1xx devices are versatile analog modules, your software application reads a linearized, calibrated, and
input modules for Compact FieldPoint and FieldPoint that can be scaled value from the I/O module, eliminating the error-prone step of
used to measure voltages ranging from the millivolt level to the converting binary values to voltage or current values. For increased
120 V high-voltage level in applications such as battery-pack accuracy and noise rejection, the [c]FP-AI-110 and [c]FP-AI-111 use a

linearize signals on-board to return scaled values to your control
[c]FP-AI-1xx modules offer a variety of update rates to fit your

NIST-traceable calibration certificates, ensuring accurate and reliable the module used and on the noise filter settings selected on the

Smart I/O Modules
With [c]FP-AI-1xx analog input modules, you can directly connect to that are not calibrated to standard ranges. For example, when
your industrial sensors or units under test and get high-accuracy configured for an input range of 4 to 20 mA, the modules actually
