Test apparatus 100 judges a test item, and when carrying out a radio transmission characteristics test, communicates layer 3 signals with mobile terminal apparatus 150 to implement radio connection over CDMA radio interface and transmit a measurement signal. A first retaining device is connected to the first surface of the resilient core. The flow flows along a flow path from the compressor to the first tower, to the first separator, to the second tower and out the outlet when the first set of valves is open and the second set of valves is closed. A flow-rate detector detects the flow rate of the processing solution supplied from each processing-solution supplier. Said steam generating unit also has a water level regulator inside the steam generator and a manual drainage that allows draining the water held in the interior of the steam generator every time it is used.
