A group of six refined sample meters was constructed and tested. Wherever possible, parts from the pilot line tooling were used. Two meters were subjected to a high impact shock study made with high speed moving pictures. The movies proved to be a valuable aid. Other meters and components were spot checked for their ability to pass such tests as overload, temperature, humidity and vibration. The meters were tested to determine their capability of passing all test requirements. All tests in Group I MIL-M-10304, 126.96.36.199 have been performed. Group II tests have been started and the Moisture Resistance test is in process. Isolated failures occurred in tests for response time, power consumption, extreme temperature, and overload capacity. Only the extreme temperature and overload failures indicate the need for more than minor attention. Superior performance was noted on temperature influence and repeatability tests of current meters.
