NI-PXI 4072

[jesusgutierrez]

HI

I have a problem, i am making measurements of current, voltage and capacitance, but when i do the current measurement, the card NI PXI 4072 is damage, I have already exchange two identicals cards and the results is the same, and always start faulting in the current measurment.

Some of the cards only no longer measure current, however if the resistance, capacitance and voltage measurements work.

When checking NI MAX, the reset and self calibration work in DMM, but the self test mak the error:

The self test failed.
Status Code:-200020
Self-test of the device has failed

Check the wiring and electrical installation and everything looks good.

thanks
best regards

Hi Jesus,

Have you tried upgrading the NI-DMM drivers?

Just to confirm can you share the NI-DMM drivers version you have, this could be found in NI MAX in the Software section.

it is also possible that your DMM needs a repair process, but we could discard the drivers issue by checking the information I am requesting.

Hi

Yes, I updated the drivers but the problem persists.

I changed the card to another PXI but the 4072 card is already damage and does not make current measurements.

My problem is that I can not fine the cause of this, and it is damaging the cards.

Regards.
