• Check that the other equipment, cables, and connectors are connected
properly and operating correctly.
• Check the equipment settings in the procedure that was being used when the
problem occurred.
• Check that the test being performed and the expected results are within the
specifications and capabilities of the power meter.
• Check the power meter display for error messages. Refer to Chapter 4 for
further information.
