Dear Muhammet Gavusoglu,

Measure Voltage and Current Simultaneously on a NI DMM can be automated in software. For more details and information about this subject, i suggest you to see links on topic.

Best regards

Muhammet,

I guess that you have a current flowing through something, from a source.

So, with one channel, measure the voltage provided to the load.

And with another channel, measure the voltage developed across a tiny (but well-known and stable) resistor.

If you know the value of that small-but-stable resistor, you can calculate the current flowing through it. At the same time, you know the voltage across the load.

Choose the tiny resistor so that it doesn't significantly alter the voltage presented to the mystery load.

Is that useful?

Dear Muhammet,

I agree with the previous answers this can be done easily in software.

If you need a hand please contact me I have a LabVIEW example that explains it very well.

Good Luck

Michele
