Request for Help with LabVIEW VI for Force vs. Time Plot using NI USB-6002 & Load Cell

[PRAVEEN__]

My name is G Vinhu Praveen, and I am an undergraduate mechanical engineering student working on a Low-Velocity Impact (LVI) testing machine as part of my final-year project.

---

       My Setup:

• DAQ System: NI USB-6002

• Load Cell: UNV-C (3000 kg, 2.0 ± 0.25 mV/V sensitivity, 700 Ω)

• Signal Conditioning: HX711 or AD620 microvolt/millivolt voltage amplifier module

• Frame: Custom-built drop-weight system compliant with ASTM D7136

---

       Objective:

• Plot Force vs. Time in LabVIEW

• (Optionally later: Force vs. Displacement)

---

 My Request:

I am new to LabVIEW and would truly appreciate guidance on:

1. Building a basic LabVIEW VI to acquire and log real-time data from my DAQ system

2. Creating a real-time Force vs. Time plot

3. (Bonus) Suggestions for Force vs. Displacement visualization
   
   
   

   I have attached:
   • A photo of my test setup
   • Animation video

I’ve successfully wired the system and can read raw voltage from lab view , but I'm struggling to create the full data acquisition and visualization setup in LabVIEW.

If possible, I would be very grateful for a brief Google Meet session (even 30–60 minutes) with an expert to walk me through the LabVIEW setup. This would greatly help me complete my project effectively and on time.

Hi PRAVEEN__, 

You mentioned about attached files, but I didn't find them, can you send the materials that you have and additional information about what exactly do you want to do.

Hi

As a starting point : 
Go to Menu - > Help -> Find Examples -> Hardware input and outpout -> DAQmx -> Analog Input -> Voltage - SW- Timed Input.vi

take a look and understand what the code is doing. 

Then you need to add some functions to save the data. 

Finally you need to understand XY plot in order to plot force x displacement.
