Can not Put More Than One Type of Measurement Into My DAQmx Task Using the DAQ Assistant

Updated Apr 4, 2018

Reported In


  • NI-DAQmx 7.1
  • NI-DAQmx 7.2

Issue Details

I want to take more than one type of measurement at the same time, for example voltage, temperature, and strain, using the DAQ Assistant to create my task. However, after I choose one type of measurement, I cannot select another type of measurement at the same time. I want to be able to run all three tasks at the same time (continuously). How can I do this without getting the Error -50103 message?


Unfortunately, with NI-DAQ 7.1 and 7.2 you will not be able to use the DAQ Assistant to create the tasks. Instead, you will need to programmatically create your task to include multiple types of measurements.
In the related links section below, there is an example program which does this for you.  The example program combines a voltage measurement, a temperature measurement, and a strain measurement all into one task that runs continuously.

With NI-DAQ 7.3 and later, you can add multiple types of measurements to a task. Follow the links below for more information.
