Conducting a continuity test assures one that the extension cord is connected directly to the ground prong and thus, the grounding circuit is complete, including the extension cord."
Designed to perform safety checks in accordance with the IEE Code of Practice (3rd Edition) and fulfilling an integral part of any health and safety policy, the HandyPAT 500 can be used for Class 1, Class 2 and power lead tests, insulation tests at 500V plus fuse tests and a 200 mA DC continuity test, making it suitable for IT and office equipment testing.
The last production test performed is the ground bond test, or earth continuity test. The purpose of this test is to ensure that in the event of an insulator failing, all accessible conductive parts of the equipment are securely connected to the earth terminal.
Again, replace it if it fails the continuity test ($40).
Inspection is performed using a video inspection system, and continuity test is conducted on all etch cuts, and "anything nearby," including innerlayers.
Lower the rail and plug the safety box cable into the tub's charge box and do the normal continuity test. If at any point a box or cable flunks the test, you know immediately what must be replaced.
The Connecticut Superior Court ruled that a surviving corporation could use the net operating loss (NOL) carryover of a predecessor corporation because there was continuity of business enterprise, and established a four-part continuity test.

Data hold and peak value display facilities are provided, along with frequency measurements and an audible continuity test. It complies with CAT IV 600V and CAT III 1000V safety standards and features an automatic power off facility to save battery life.
Continuity test indicates open or high-resistance terminal connections, and the DC test mode eliminates errors due to magnetic buildup.
If the outer conductor is stretched and a hairline crack is formed, it would be very difficult to detect during a visual inspection and would probably even pass a continuity test. The result would be a defective circuit that could very likely end up installed in the finished assembly where handling and/or vibration would almost surely cause the conductor to open.
