To perform the Kelvin check, each node has the sense line shorted to ground and the power line is energized with a low voltage.
If the connection between the power and sense lines is poor, the easiest path for the current to take is through the current sensing shunt and a large current will be measured.
If the connection is strong, the current sensing shunt will be bypassed, and the measured current will be small.
Any resistance lower than 5 Ohms from power to sense will pass the test, and any resistance higher than 10 Ohms will fail the Kelvin check.
If there are one or more failures, a failure report will be shown which indicates which node number failed and a terminal name that corresponds to that node.
This screen then provides three options. The user can adjust their connections to resolve the issue and retry, ignore the failure and continue with testing, or ignore the failure and abort the testing.
In the case of retry and ignore, the execution is resumed by pressing the RUN button.
