Cmd line lcr gives wrong values

I have the following problem using the lcr extension module:

Since there is no timestamp included in the measurements within the webapp, I used python to establish a SSH connection with the redpitaya 125-14. Then I used the lcr cmd line tool to measure values and added a timestamp within python. Everything worked out until I wanted to check the measured values:
I connected a 1 Ohm resistor. Via the webapplication of the lcr meter this was measured in an accurate way. In the cmd line tool however, I get really buggy values for the resistance, that are up to one order of magnitude different than the real resistance.

I used the following settings and have the right channel selcted:
lcr 1 0.4 0 0 1 0 0 0 2 0 1000 1000 0 0

I wold really appreciate some help.

Thank you!
