美国采购需求：电子、照明

I hope this message finds you well. We recently discovered that we've misplaced the instruction manual for our watt meter. Unfortunately, we can't locate it and are in need of guidance to operate the device effectively. It would be greatly appreciated if you could send us a digital copy of the manual or direct us to where we might find it online. Additionally, any tips or troubleshooting advice related to the product would be helpful as we navigate its features. We value your support and look forward to your prompt response on this matter. Thank you for your assistance!
