That's an excellent wattmeter, at a good price. It's the same model
I use for my TC work. I live about 15 miles from Newark NJ BTW. It
will give true watt readings on reactive loads unless there are
harmonics above 133Hz that upset it's behaviour. I consider it to be
accurate enough for my work. I'll be interested to hear of your findings
with your coil using the wattmeter.
