How do you use a test meterto test 415v across phase?

To test 415V across phases using a test meter, first ensure the meter is rated for the voltage you are measuring. Set the meter to the appropriate AC voltage range and connect the probes to two of the three phase conductors. Ensure proper safety precautions are followed, such as wearing personal protective equipment (PPE) and verifying that the area is safe for testing. Read the voltage displayed on the meter to assess the voltage between the selected phases.
