I'm trying to measure high voltages with a DAQ card. Obviously I'm going to have to attenuate the voltage, but I need to make sure that I can measure accurately (within 1%)
The code width of the DAQ is
Vcw = 20Vpp/2^16 = 305.176uV
For this code width to be within 1%, the minimum voltage I...
Can you show me some documentation or guide me on this volts per meter thing? This will definitely be important when I choose my resistors. I cannot seem to find this parameter on a datasheet.
The circuit that I am going to build will be an instrumentation amplifier with several attenuation stages to scale 800Vrms down to 10Vp. The gain will be auto adjusted in LabVIEW. The students (this project is for upgrading the lab) will not be expected to set the gain manually. I have a...
Our power lab has the old Hampden Benches from the 60s. But we have one module from LabVolt. My project is to build a data acquisition system that is cheaper then the LabVolt system that we have. (Not as good though)...
Ahhh. That makes a lot of sense now. 60Hz IS the resonant frequency. duh!
Thanks for your response. The only issue is, I cannot lower the voltage for this application. The project is to observer voltage and current magnitude and phase relationships at a source voltage of 120V rms. I suppose I...
Hello all,
I am a senior electrical engineering student at Purdue University and I am working on my senior capstone project. One of the aspects of my project is to measure voltage and current waveforms as well as the relative phase shift between them. I need to get these waveforms into a data...
