Power outlet test
Before starting the tests, the power outlet from which the monitoring device will get
electrical power must be checked. This test checks the condition of the power outlet
to ensure correct results from leakage tests.
For international power outlets, refer to the internal standards agencies of that
particular country. Use a digital multimeter to ensure the power outlet is wired
properly.
If other than normal polarity and ground is indicated, corrective action must be taken
before proceeding. The results of the following tests will be meaningless unless a
properly wired power outlet is used.
