Hi,
I recently set up my Red Pitaya (125-10) with the LCR meter, and the readings are 1) extremely inconsistent (jumping around many orders of magnitude with auto-shunt, and +/- 20% or so with manually determined shunt), and 2) plainly incorrect. With a 100 Ohm resistor (measured externally as 99 Ohms) as the DUT, with 100Hz and 10 Ohm shunt it reads ~44 Ohms (~0 Deg but jumps between -5Deg, +5 Deg, so that seems correct).
Capacitor measurements were jumping between nF uF and OVER R. regardless of which settings.
I followed the hardware instructions and set the jumpers to high impedance mode, checked all SMA cables are securely attached, the BNCs are wired so the two leads associated with the red clip are plugged into LS/LD, and the other two are in HD/HS.
I'm not really sure what else to try (I've even updated the SD card with the latest stable version). Any suggestions would be greatly appreciated.

Re: LCR Meter Measurements Wrong
please let me know if the issue is manifesting after you manually update the Red Pitaya OS to the latest BETA by using this specific guide:
