Set C-DAQ 9203 to bipolar

[HVAC_master]

How do I set my 9203 current sensing daq to bipolar mode?  Right know the DAQ Assistant sub VI is set to recieve from -20 to 20m, but that does not seem to do it.  Negitive current flat lines at about -800uA,  Any ideas?

Hi Kevin,

Since the DAQ Assistant is set to -20m to 20m, then you should be in bipolar mode already. How do you know that it is railing at about -800uA? It might be possible that something else is affecting the measurement and causing the railing issue. The way you have it set, you should be able to see measurements below -800uA.

I was an idiot and set other channels to -20m to 20m; but the channel in question was set to 0 to 20mA.  Thank you Aaron.
