Using the hygrometer:
Ensure that the chamber at the bottom of the wick of the wet thermometer is filled with water and that the wick is wet. Read the wet and dry thermometers. Subtract the wet bulb measurement from the dry. Examine the table on the hygrometer, and read the humidity off the table using your wet-dry thermometer measurement.
