Add _boardTempSensor_vs_aignd to existing task

[Taki1999]

Based on the numbers I'm getting compared to the Calibration temperature, I'm pretty sure _boardTempSensor_vs_aignd returns degrees C.

Thanks for your quick answers, now everything is clear.

I'll check it asap.

Summarizing 3 ways of reading the onboard temperature:

1- DAQmx Calibration Info property node, instantaneous temperature in degrees Celsius.

2- DAQmx Create Virtual Channel using the instance AI Temp Built-In Sensor, can be continuous reading also in degrees Celsius.

3- DAQmx Create Virtual Channel using the instance AI Voltage, then the voltage has to be converted according the KnowledgeBase scale.

Thanks again,

Marc.

Marc,

To convert the voltage returned by the _boardTempSensor_vs_aignd for your M-Series device use the following formula:

Temperature in Celsius = ((-1 * voltage read) - 0.5) * 100.

It appears as though the reference knowledge base has not been updated for M-Series devices.
