Urgent Help!

Dear All

I  have some problem. I have the programmable power supply (RS232) and DAQ to collect  Sensor datas. The DAQ sample rate is set to be 0.01Hz.

But when i try to set ON,voltage and current of the power supply there is delay of 100sec.(the same with DAQ collect data).  I tried the power supply out and inside of the loop with DAQ.

Any one can help me... to make ON and set current and volatge with out any time delay.

Thxs.

0.01 Hz equals 100 seconds per period

Increase the frequency but don't increase the voltage with each step

Dear Albert

Yes it is 100sec. But being my process is slow process i have to collect the data per 100secs.  What i need is to make the power supply functional with out delay time (to make it ON/OFF , set volatge and current)

Thx

It certainly won't work with your existing code and a sample rate so low. Post the code with the separate loop. That should work so you need to show it so someone can understand your mistake.
