5.1.9 Ruggedness
Each device comes in a weather proof enclosure and has a built in lock. All connection
ports are ESD protected. The device’s enclosure is not capable of handling submersion.
5.2 Beta Testing
The purpose of the beta testing phase was to test the devices various feature sets
together in varied stages of completeness. The beta testing was broken down into three
distinct phases. Phase one’s pu rpose was to test a stand-alone device supporting one SDI-
12 sen sor, the s cheduling framework, and basic WASUP communications to connect to the
PC. Phase two tested all sensor interfaces, the SD card, and LCD user interface. Phase
three tested the ZigBee radio network and advanced WASUP options. At the end of the
third phase, the testing of all features would be complete and the device would be ready
for its production review. Figure 5.2 shows the assembled circuit board cover inside the
enclosure that was used during this phase.
