Wheel Analytics WA-1 controllers are checked with in-house testing tools including the one pictured, the Islandix Digimatic Signal Generator. It emulates a pair of Mitutoyo digital indicators, which allows each WA-1 to be tested with an external signal source. The tester generates readings at eight times the peak indicator data rate in order to expose tolerance problems (circuits are more sensitive when run faster). Both ports are bombarded with over a million samples, each decoded, processed and relayed over Wifi and USB simultaneously for a full-coverage test at impossibly high data rates. Software verifies no readings are lost and no transmission delays are experienced.
