EVAL-AD5941BATZ icw sensorpal not working as expected

Category: Software
Product Number: EVAL-AD5941BATZ
Software Version: 2.5.2.6.

Dear All,

I have been experimenting with the EVAL-AD5941BATZ in combination with sensorpal and I seem to get some incorrect results.

- The first problem I encounter is that when I open sensorpal en want to do a battery impedance measurment, I need to drag the Battery impedance block to the work area. When I do this, immediately sensorpal(v.2.5.2.6) crashes. I work around this by starting with a linear sweep  voltametry, starting the measurment and then drag the battery impedance block which allows me to start a battery impedance measurment.

- Once I started the measurement, I would get some unexpected results, I hooked it up like figure 13 of https://www.analog.com/media/en/reference-design-documentation/reference-designs/CN0510.pdf also found in this link https://wiki.analog.com/resources/eval/user-guides/circuits-from-the-lab/cn0510 Both with a standard 18650 battery and a simple resistor I would get (random) results from the freuqency plot. Attachted is a photo of the result with a resistor and how it is hooked up.

Setup:

Result(0.5R between F+/S+ and F-/S-):



My question is: Am I doing something obvious wrong? I have tried two different board combinations ADICUP3029 + AD5941BATZ.

Kind regards,
