NAOJ GW Elog Logbook 3.2
At some point, we have to put the instrument control system racks in the humid environment of the tunnel.
I borrowed a plastic cover from DGS and put it on one of the racks. Then I turned on the system. I also put a temperature meter.
I will leave it like this until tomorrow to see if the temperature goes up high enough (above 30C).
If the temperature is high, we can expect the local humidity to drop accordingly. So we can move the rack to the field.
Right now, the wrapped rack is sitting in front of the shutter.
I checked the temperature inside the rack after about 24 hours. It was 23.9C. The temperature raise is too small. I will look for a way to generate more heat (heater) in a controlled way (slidac ?).
