Test aircraft storage battery containers for defects.
What does an Electric Container Tester do?
Tests aircraft storage battery containers for defects, using dielectric testing device: Places storage battery container on table and connects cables from testing device to battery. Starts device that transmits high voltage electric current through battery. Observes dial on testing device that indicates if container has any defects, such as cracks or holes. Stops device, disconnects cables, and places tested battery aside for further processing. Marks defective battery, using chalk.
