Measurement Fundamentals - Measuring Voltage or Current (Analog Input)
In this lesson, you learn how to select and connect to hardware, configure the DAQmx task appropriately, and validate an analog measurement.
Audience
- Developers using LabVIEW with NI data acquisition hardware to create data acquisition applications
- Users familiar with the DAQ Assistant or basic NI-DAQmx code that want to expand their programming capabilities
- Users new to PC-based data acquisition and signal conditioning
Task-based objectives
- Select the right data acquisition hardware based on resolution, range, and sensitivity
- Determine the correct sample rate to avoid aliasing and get the data you need
- Recognize the proper grounding configuration for connecting an analog input signal
- Understand the options for configuring the DAQmx Create Channel VI to achieve an analog input measurement
