Strain Acq with Calibration

[ThaDrewid]

Hi I would like to know if there is anyone out there who has a nidaqmx code sample that performs continuous strain channel data acquisition with bridge nulling and shunt calibration. There is a VI that illustrates how to do this in nidaqmx but no convenient code example that I have found. Thanks in advance for your help.

Greeting Drew,

Currently, the routines for nulling and calibration have not been created for text-based programming languages. You can create these routines using channel properties in NI-DAQmx (DAQmxGetAIBridgeBalanceCoarsePot, DAQmxSetAIBridgeBalanceCoarsePot, DAQmxResetAIBridgeBalanceCoarsePot, DAQmxGetAIBridgeBalanceFinePot, DAQmxSetAIBridgeBalanceFinePot, DAQmxResetAIBridgeBalanceFinePot, DAQmxGetAIBridgeShuntCalEnable, DAQmxSetAIBridgeShuntCalEnable, DAQmxResetAIBridgeShuntCalEnable, etc...).

We are currently working on these routines and they will eventually be available. I hope this helps.

Is there currently any timetable for implementation of these routines?

Hey Drew,

This should be incorporated into one of the next updates of the NI-DAQ driver. Unfortunately, there isn't an exact date but the earliest would probably be the middle of this year.
