K8115 Component tester

I assembled the component tester. Now I try to do the calibration, but when connected the 3 probes. de display reads 0.1 and 0.3 ohm an not allow me to go to the second step of the calibration.
What to do next?

when you disconnect the wires and short the 3 pins at the connector on the PCB, does it work then?

Hi I have the same issue. Kit appears to wotk correctly. I hower could not finish calibration. I ger an error after texting components successfully saying “ not calibrated”
