Abstract:

The bell was set up at this Laboratory in a standard test circuit and closely observed for its operating characteristics while under test for endurance, over and under voltage and frequency, inclination, and shock. The usual tests for current consumption, power factor, insulation resistance, dielectric strength, audibility range, and watertight integrity then followed.
