GENERAL INFORMATION 2.1. General Description of EUT Equipment: Temperature Sensor Model Name: WSC-IS Series Model: WSC-OS Model Difference: All model’s the function, software and electric circuit are the same, only with a product model named different. Test sample model: WSC-IS. FCC ID: VA8-WSC-IS Antenna Type: Internal Antenna Antenna Gain: 1dBi Operation frequency: 915MHz Modulation Type: GFSK Power Source: DC 3V from battery Power Rating: DC 3V from battery Page 7 of 23 Report No.: HK2205242169-E 2.2. Description of Test Setup Operation of EUT during testing: The sample was placed (0.8m below 1GHz, 1.5m above 1GHz) above the ground plane of 3m chamber. Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3 axis (X, Y & Z) and considered typical configuration to obtain worst position, manipulating interconnecting cables, rotating the turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations. The emissions worst-case are shown in Test Results of the following pages. The worst case is X position. EUT Page 8 of 23 Report No.: HK2205242169-E 2.3.
