The Neslab chiller is working well. It's temp display shows 20.0 C rock solid. Flow meter rotating at 13.5Hz at the out put of the chiller.
The MOPA temp was measured with a hand held thermocouple . The PA was 34 C and 29 C at NPRO heat sink.
The NPRO flow meter was not rotating at this time. There was just trickeling water flow though the meter.
I closed the needle valve this point. It needed 8 turns clockwise. This drives head temp to 19.9 C
Than I opened the needle valve 9 turns and the flow meter wheel was rotaing at ~ 1 Hz
We gained a little power. Can you explain this?
