To see how the temperature and humidity go, in order to make strategies for the power shut down planned next week, we did following procedure and will see how the temperature and humidity go in the PSL booth.

- Air conditioner was turned off

- Front panel of AC was covered by a plastic sheet so that the outside air doesn't come in

- 6 of 8 Koach filters were turned off (two at upper center were left on)
