Help with adjust procedure for NI USB 4065

[Sakul20]

Hello,

Sorry , but I am new in LabVIEW, I am using version 2013....

Now I need adjust my NI USB 4065, I maked adjust procedure, which you can see in attachment, but doesnt work....

I need adjust only 4-wire ohms... please could you help me?

Thanks you so much

Please help me... It is difficult for me... I have to adjust all funnctions? Or can I adjust only 4-wire resistance?

I don't know where is a problem... every time I see error "this function doesn't work"...

thanks you very much

Hi @Sakul20,

Yes, you will need to configure your software functions according to your hardware configuration. Is there an exact error code associated with the error you are seeing? If so, what is it?

Hi Letitsnow,

Yes, I see "Error -1074118134 occurred at niDMM Cal Adjust Gain.vi, Possible reason(s):
This calibration step has been performed out of order. Please, refer to the external calibration procedure for the correct calibration sequence."

I start adjust with 1Mohm...

Thanks you so much

Sakul20,

The Error you are getting indicates the code is currently configured incorrectly.  Have you read through the Calibration Procedure for this device?  It outlines exactly what you need to do based off the hardware configuration you are implementing.

Hi red.free,

Yes, of course, I read it, but I am not good in English.... I have to prepare verification before I start adjusting or I can start only with adjusting....

i have to start with linearisation or I can start with 4-wire resistance adjustment...

because i think, I can start only with adjusting 4-wire resistance without verification proves, or not?

thanks you so much

Hi Sakul20,

The calibration process includes the following steps:

1. Initial Setup—Set up the test equipment.

2. Verification Procedures—Verify the existing operation of the device. This step confirms whether the device is operating within its specified range prior to calibration.

3. Adjustment Procedures—Perform an external adjustment of the device that adjusts the calibration constants with respect to a known voltage source.

4. Reverification—Repeat the verification procedure to ensure the device is operating within its specifications after adjustment.

You can start with adjustments. You will need to perform any verification after adjustments have been made. I hope this helps!
