Custom Scaling Error 200077

[DanielDerer]

Hello,

I have a cDAQ-9188 chassis and seven modules. My VI consists of a DAQ-Assistant to acquire signals. With this I created a channel "Luftdrucksensor". For the Calibration I used a Custom Scaling in which I created a characterisitc curve. My sensor has an output range of 4-20 mA and 0,9-1,1 bar. But when I want to start the measurement an error occurs.

Can you help me?

Thank You

Regards

The min and max must be in terms of the scaled value, not the 4-20ma unscaled measurement.

Hello,

thank you very much, it was successful.

Just for the understanding, why must there the scaled values? In my task the other pressure channels can handle with a range from 4-20mA, whats the difference?

Thank You

I suppose that technically, the limits could be installed but for ease of use, readability, consistency, I makes more sense that the limits are referenced to the scale.

Hello Recently I have a same question,I have a cDQA-9178 chassis and NI 9213 modules,and I want to acquire Voltage signals,when I click save and run the dialog show:Error -200077,then I search a example: Voltage and Thermocouple in a single Task.vi in Labview software and try again. it also gave me a one ERROR dialog.can you help me ? Thank you very much!
