With my pda and the 6024 DAQ I am measuring only negative voltages

[mhasler]

I am using LV 7.1 PDA and a 6024 PCMCIA DAQ Card. Measuring works fine but all positive voltages are cut off. In the configuration utility I put the settings on bipolar, RSE. What's wrong?

Hi Michael,

which DAQmxBase driver are you using? I attached a link to the DAQmxBase driver 1.5. This is the latest driver which supports LV PDA 7.1

Can You test the PCMCIA card in a laptop to verify if the card is working properly. You set the card to bipolar. Which input range did you set?

Mayby it is set to a negative range.

Thanks
