I am wondering if anyone out there has a program written for an oven Uniformity test. I am currently using an ENET 9213 for thermocouple acquisition of my temps. When I do my uniformity test right now I just manually watch the data. Below is the basic steps of what the uniformity test does.
1. Thermocouples in 9 zones.
2. Monitor temps and once one zone reaches the allowable range (setpoint +/- 10 degrees Fahrenheit) all 9 zones have to reach the allowable range within 20 mins if not tests fails.
3. Once they all meet that first criteria. All 9 zone have to stay within that allowable range for 40 mins.
This seems like it should be a simple enough code but I am new at this, still going through my Core 1 and Core 2 class. but I just can't seem to get it figured out.
Any and all help would be greatly appreciated.

- First, you need to acquire data correctly. So you could test your devices on NI MAX (test panels or tasks), then you could use the LabVIEW examples for analog input>>temperature acquisition. Start from LabVIEW examples.

- Once you are acquiring all your data correctly, you could check the maximum and minimum values and display alerts using indicators. You are going to implement timing VIs.

I will look at these when I get home. Thank you for your input and I will let you know what I come up with. If i am able to pull this off i will figure out how to post as an example.
