Steve, Rob and Alberto
Starting capacitor 216 miroFarad was installed on the compressor. Water lines were connected to the MOPA as corrected, so the flow meter readings are logical.
Now IN means flowing water in the direction of black arrow on the hose.
We struggled with the Neslab presetting: temp, bauds rate and other unknowns till Rob found the M6000 manual on Peter king's website.
Alberto realized that the chiller temp had to be reset to 20C on water chiller.
I put 1mg of Chloramin T into the water to restrict the growth of algae in the bath.
The NPRO heat sink was around ~20C without flow meter wheel rotation and the PA body ~25C by touch of a finger
I just opened up the needle valve a litle bit so the flow meter wheel would started rotating slowly.
That small glitch at the end of this 3 hrs plot shows this adjustment.
