回應： PXIe-4141 Calibration Error niDCpower version 1.8 ,"calibration function is not supported by the device."

[PeterChang]

Dear sir,

Nice to meet you.

When I running the PXIe-4141 Calibration Function "niDCPower Cal Adjust Voltage Leve.vi" in niDCpower version 1.8, 

it will show an error "calibration function is not supported by the device."(false cae)

But if I run the PXIe-4141 Calibration Function "niDCPower Cal Adjust Voltage Measurement.vi", (true case)

it will work.

See the attachments.

My Equiptment list:

WinXP SP3

Labview 2011

niDMM 3.0.5

niDCpower 1.8

PXI-1073 case with 2 cards.

slot2: PXIe-4141

slot6: PXI-4071

Could someone tell me the solution?

Update:

Error Code: xBFFA4A42

niDCPower Cal Adjust Voltage Level.vi<ERR>Requested calibration function is not supported by the device.

Status Code: -200445

See "voltagle level error.JPG"

And the same error for "niDCPower Cal Adjust Current Limit.vi".

See "current limit error.JPG"

Hi Peter,

Thank you for the detailed description of the issue you're having.

Looking at the adjustment section of the NI PXIe-4140/4141 Calibration Procedure, you'll see that only 4 of the functions from the NI-DC Power Calibration subpalette are mentioned.  They are below:

• NI-DCPower Cal Adjust Voltage Measurement
• NI-DCPower Cal Adjust Current Measurement
• NI-DCPower Cal Adjust Residual Voltage Offset
• NI-DCPower Cal Adjust Residual Current Offset

If you call any calibration VI other than these 4 during a 4141 calibration session, you will generate error -200445.  

The other VI's in the NI-DCPower Calibration subpalette are used when calibrating other NI-DCPower devices.

Let me know if you have any more questions.

[PeterChang]

Thanks a lot.

I found that PXIe-4141 running "NI-DCPower Cal Adjust Voltage/Current Measurement"

 ware equal the Other cards running "NI-DCPower Cal Adjust Voltage/Current Level/Limit" could let the Voltage/Current Output be adjusted.

It's very easy to be confused...

And how do I do when adjusting the measured value by PXIe-4141 ?

By the Self-Calibration?

Hi Peter,

The calibration procedure states that calling the NI-DCPower Cal Adjust Voltage Measurement function calibrates both the voltage output level of the device as well as the voltage measurement capabilities of the device.  The same is true for the NI-DCPower Cal Adjust Current Measurement function.  

You should perform a self-calibration on the device before initial verification of the device, before the adjustment process, and before the final verification process.

I am not sure I fully understand your question.  Please let me know if I have not answered it sufficiently.

Crystal Clear.

Thanks again.
