PXI-6289 self calibration failed Error -200545

[gaminn]

Hello,

my PXI-6289 self calibration fails. I checked it  with DAQ Diagnostic Utility 2.0:

-------------------- Testing Analog Input... --------------------



Testing AI Ground Reference...   (PASS)



Testing AI Voltage Reference...   (FAIL)

************ Test FAILED for the following reason ************

Analog Input was not within tolerance for reference voltage.    Expected to read: 6,950000  Actually read: 0,187908

*******************************************************

-------------------- Testing Analog Output... --------------------



Testing AO Finite Sample Clock...   (PASS)



Testing AO Finite Sample Clock Frequency...   (PASS)



Testing AO Single Point...   (FAIL)

************ Test FAILED for the following reason ************

This test failed to output 1,000000 Volts on PXI1Slot5/ao0.  The actual value written was 0,034417.

*******************************************************

I had an issue with 12V supply rail - fuse F5 blew. I changed it, but the same problem still exists. I measured voltages on L1 through L8, are they OK?

L1: 0.7 V

L2: 20 V

L3: -20 V

L4: 38 V

L5: 12 V

L6: -12 V

L7: 20 V

L8: -20 V

What else should I check?

Thank you

Martin

Hello Martin,

Just to be sure - have you disconnected all wires from the card when performing self-calbiration and running the Diagnostic utility?

What are those voltages you've measured?

Thanks,

Hi Jakub,

yes, I disconnected all wires. The card is unfortunately malfunctional...

The voltages are measured on small inductors marked L1 to L8. Are the voltages correct? I would like to know if the problem comes from power supply of the board or whether it is bad analog part.

Thanks

Martin

Hi Martin,

Unfortunately I cannot check these voltages and tell you where the problem is. I suggest you to write an e-mail to techsupport@ni.com with link to this thread and a serial number of the card to start the repair process. Your e-mail will be redirected to proper local support, so you can use your local language.
