Measurement of Micro Ohm with DAQ6510

Post by lucianogarc » September 7th, 2019, 2:33 pm

Dear all

It is possible to measure micro Ohm values using DAQ 6510?

How is the process using the rear panel? Or, If its not possible, any chance using the front panel?

Thanks.

The DAQ6510 has a 1 Ohm range with 1uOhm resolution.
However, let's look at specs to have an idea of allowed error.

The 1 year specs for 1 ohm range are: +/- (0.0085% of reading + 0.02% of range)

Just the second term, 0.02% of 1 Ohm range, will give 200uOhm of allowed error.

The DMM uses 10mA of excitation current for the 1 Ohm range.
If possible, you would be better served with an external current source to push more than 10mA through your DUT. This would yield a larger and, in theory, more measurable voltage from which to compute the R from the measured V and sourced I.

Dear Andrea,

Thank you for the support until now and all your help.

Do you mind if I forward you some doubts that I have in my Test Settings including cable configuration and specification as well as photos.

I think it will be of a very nice support If I can send by e-mail.
