How should the power meter be connected and illustrated
The drawing instructions, do not need to measure the ballast power, need to use electric parameter tester, two into the wiring behind instrument input refers to the side, measure the ballast output is to connect power at both ends. After a complete set of ballast system connected, the power cord at the input connected to the ballast system, so that will be displayed on electric parameter tester, ballast working current, the overall power (power consumption), and its power factor.
You can't use a multimeter to test with a special instrument.
Access to the power source is available, and the power meter displays the actual power of ballast and its payload
