These should be around 50mV. If they are lower, adjust VR1 and VR2 accordingly.

Now I have 0.25Volt on R1 and R2, at the Vout pots I measure 12Volt and 300mA with no load. When I will connect the Legato board and trim the value of R13 and R14 to 50 mvolt...will I measure 250 mA at the V out ? Thanks for your helpfull reply Gianluca

First you do the rough setup, then you fine tune the pots with the load connected. The fine tuning will make sure you're shunting what is needed for your setup (meaning your specific Legato & Placid combo): no more, no less. Please make sure you follow the right procedure for your version of the Placid BP. R13 and R14 are only to be used on V2.1.2. See the Placid BP manual for details.
