Can any friend correct my first DC Voltage measurement experiment? Please also open the PDF file for the graphic description.
Equipment and Software:
1. NI LabVIEW 6.1 version
2. CB-68LP, PCI-6024E, PCI-6035E and Analog DC power supply
My process:
1. Connection setup as shown in below figure (see the attached PDF file). I connect a R6868 ribbon cable to either PCI-6024E or PCI-6035E card. Use AI to feed DC voltage to CB-68LP. The input voltage is from 1 DCV to 10 DCV.
Question: Is the connection setup correct? Is my concept correct? Can it measure an analog DC voltage and read the same analog output DC voltage as shown on LV screen?
2. I found that PCI-6035E is selected as Device 1.
3. I found and opened an example, Continuous Voltage Measurement.vi from LV 6.1 as shown below. Once turn the power supply ON, the voltage read nothing and keep on running as 0 V.
Question: Is the default example ready (Continuous Voltage Measurement.vi) to measure an analog DC voltage from CB-68LP? Do I need to change the Continuous Voltage Measurement.vi?
4. I changed the Device as 2 and increased the high limit to 8.00V; the reading value is 10V no matter what input I feed in.
Question: What happened here? I am starting doubt my IQ.
5. I also tried to change the Device 2 but I could not change the channel selection (see page 5).
Question: How do I change it?
I just could not find how to change the Configuration for Device 2.
Thank you for your kind help!
